Abstract The project focuses on the Tamar Estuary, located in Plymouth, a coastal community south west of England that strives for marine tourism. In response to marine tourism, Plymouth intends to expand its primary industry by proposing a national marine park. However, the existing fishing industry is slowly being forgotten by absence of a developed marine spatial planning and a lack of space along the coastline. Intertidal mediations examine the development of coastal communities, cities located along the coast, in the United Kingdom. Many of these cities have a primary mode of production such as marine tourism, fishing, wind farming, agriculture, etc. As the coastal communities develop, natural resources are exploited through the means of mode of production (Cosgrove 52). However, the exploitation of natural resources, in this case the sea and coastline, provides a conflict between the different actors, creating competition for marine real estate. The marine resource in the United Kingdom are competed for along the coastline. There is a disproportion of coastal ownership and development. Disproportion of coastal economies are due to the lack of a developed coastal and marine spatial planning. Many of these communities are focusing on primary mode of production without the alternative means of economic balance. The project looks specifically at the intertidal areas in Plymouth, which provides an opportunity to expand into other industries while accommodating for the existing fishing community and a future national marine park. The research looks at redefining marine management by informing a design policy that influences the decision making of todayâ&#x20AC;&#x2122;s marine spatial planning. Through various tests, the project looks at physical and digital techniques that informs a diverse landscape that allows for diverse economic prosperity. Through the role of a designer, the deployed techniques include interactive mapping and physical low tide simulation model to assist design decision internally, but not limited to internal use. Through careful case studies, the project seeks to utilize structures at the architectural scale to better inform the development of diverse marine use at the intertidal areas within Plymouth. This scale can be extrapolated at multiple scales to better inform decision making amongst the local actors. Through various scenarios, the project works through the variable of time: economic fluctuations, constant changing of tides, sediment accumulation and eroding processes.

In the diagram below, the project examines the existing conditions of Plymouth and its surrounding context. In contextual boundaries, the chapter 1 explores the limitations of Plymouth fisheries, marine management, and New Economic Foundation. By understanding the wider contextual influences in the United Kingdom, Plymouth is affected by the existing and projected site conditions, seen in chapter 2 to 4. The project then explore digital techniques to negotiate among the stakeholders in chapter 5, familiarize with existing creek formations and utilize creek formations in chapter 6, develop along creek formations in chapter 7, and deploy technique at multiple scales in chapter 8. This process is a way of redefining a role of a designer to take decisions at a top down approach.

Prologue

01| Contextual Boundaries The project examines the existing economic opportunities and management in Plymouth, United Kingdom. Plymouth, claims to be Britainâ&#x20AC;&#x2122;s Ocean city, celebrates its marine heritage with many marine activities ranging from marine recreational activities to local fisheries. The city thrives on the varying economies, primarily in marine tourism. Although with the cityâ&#x20AC;&#x2122;s success in marine tourism, the city and as a country currently lacks a developed marine spatial management, equivalent to spatial planning for land. By lacking the ability to manage the cityâ&#x20AC;&#x2122;s sea and coastal areas, the city plans to propose a national marine park, discussed in chapter 2, thus relying on a primary economy without relying on alternative economies. Additionally, the project works with a non-profit organization, New Economic Foundation, examining the need for a diverse economy to allow for coastal communities to be resilient by balancing the varying mode of production. As seen in the drawing above, the existing fishing industry plays a big role within the community and the interaction along the English Channel as a natural resource.

Prologue

Fish for Thought Plymouth Fisheries | Main Hub Plymouth

Plymouth plays a big role in the fishing business within the United Kingdom. This is an underappreciated industry and the United Kingdom takes a big role in this economy. Since Plymouth is the main fish market hub in the south west, the city supplies fish throughout the entire UK. This will be further discussed in chapter 2. Fish is important the United Kingdom. In the larger scale of the fishing industry, more than half of the fish in the United Kingdom are exported outside of the country. While most UK consumed fish are imported mostly from the European Union. The global economy plays a role in the territory it faces with the fishing policies and maritime boundary limits (Carpenter 4). As the mode of fish production increases, the economy plays a role in shaping the territoriality of the economic sea boundaries (Elden 800). Through capitalistic interests, nautical boundaries are drawn to define where fishermen can go. The fishing industry is a complex system with different quotas for each fish and different exclusive economic zones. Most of the fish caught in the United Kingdom exported to a foreign country, approximately 76% (Carpenter 4). Since the seas have economic exclusive zones, EEZ, fishermen throughout Europe and United Kingdom fish in the same EEZ and 12 nautical mile sea limit boundary. By allowing the fish vessels to catch seafood in the same boundaries, European Union and United Kingdom are able to share the allowable catches by trading amongst each other(Carpenter 18). However, Brexit plays a role of gaining British seas all for themselves. This notion of British seas lead to a surplus of fish since Britain does not have enough existing fish infrastructure to process all fish for trade. This stems into negotiating territorial seas between European Union and the United Kingdom. The imports and exports are currently exhibiting insufficient middlemen management in the fishery business. The territorial sea conditions begin to influence the supply and demand of the market, thus creating inefficient movement of fish from one facility to another.

Maritime Limits Lack of Marine Management United Kingdom

Currently, marine spatial planning is in the beginning phase of development in the United Kingdom. There is a lack sea planning strategy that rivals the equivalent land planning. As of now, marine spatial planning is composed of layered geospatial data. The database is static and does not respond well to a changing landscape. As shown in the drawing to the right, marine spatial planning is zoned in arbitrary drawn lines without considering the fluidity of the marine landscape. A need for a better marine plan is discussed in chapter 2. With the lack of marine management, there tends to be a disproportion in economic development in marine areas.

New Economic Foundation The Blue New Deal United Kingdom

The project further coordinates with a non-profit organization, New Economic Foundation, to develop a more resilient coastal community. Many coastal communities rely on a primary economic strategy, which lends itself to instability and unhealthy local economy (Belata 9). The team coordinated with the organization to understand the importance of a diverse economy and understand the need of stakeholders. Various stakeholders are left forgotten due to the incremental development of coastal communities, such as local fishers in East Sussex, Grahamâ&#x20AC;&#x2122;s story to build a better coastal community (Belata 32). The New Economic Foundation advocates for small actors to provide a resilient community, allowing for communities to retain economic alternatives. In relevance to Plymouth, New Economic Foundation and a diverse economy is further discussed in chapter 4.

02| Competitive Quay This chapter looks at Plymouth, Britainâ&#x20AC;&#x2122;s Ocean City. The city prides itself on its marine activities. However, existing conflict occurs in the coastal areas of Plymouth, especially in the Sutton Harbour. In the map to the left, there is a conflicting interest with the marine tourism outnumbering other harbour uses. This indicates a high concentration of marine tourism economy, with little interest in other industries. The fishing community feels constrained and without further room to grow. This is problematic to Plymouth because the city is not diversifying its economic portfolio. Chapter 4 further discusses the negative impacts relying on one primary marine industry in the Blue New Deal. Additionally, this chapter further discusses the plans Plymouth is proposing in the future in celebration of its marine heritage and marine management.

As one of the most port cities in the UK, Plymouth has the most major economies spreading along the central coastline. Marine related businesses thrive around the major harbours supporting thousands of local employment opportunities. According to research and report, the marine tourism has pumped £28 million into the local economy while £13.5 million come from fishery industry (Plymouth City Council 78). As for now, there are many commercial and retail business present in the city coast and recreation activities comes along with the fishing community. Most of the revenue source from recreational activities includes kayaking, boating, kiteboarding and yachting.

Intertidal Mediations

According to the research, Plymouth Fisheries stand as the second biggest fish market in England within the Sutton Harbour, one of the most historic harbor in the city, and it has provided around 560 fishery jobs out of 770 jobs and generated ÂŁ28 million a year for the local economy (Plymouth City Council 78). However compare with the amount the revenue generated in the harbour, the marina portion contribute much less jobs and profit than the fisheries while it took over majority parts of the harbour space. As seen in the image below, Plymouth fishing community is located in the red, where fishing community is limited 23 boats within 400 recreational boats. There is a lack of space for the fishermen in Sutton Harbour.

First National Marine Park United Kingdomâ&#x20AC;&#x2122;s first national marine park Plymouth

Since 2013, the idea of creating the first National Marine Park in Plymouth area has been brought up in several marine conferences. Last year, the newly dominated Members Parliament Luke Pollard has pushed this concept into a much more realization. Besides the protection of recreational use and ecological habitat, the marine park is about boosting its tourism economy and trying to attract more investors into the new development. However, questions rise against this concept as a marketing tool for the tourism business in particular while neglected the lack of voice in fishery business, which could bring the conflict between the two over the use of water and space. The idea is still undergoing its definition as a unique marine park for Plymouth, whether it is about the protection and promotion for the recreation activities or the re-configuration and development of the boat parking facilities. United Kingdom currently do not have a single designated national marine park. What does a national marine park mean? National marine parks give this impression of a positive effect to a community and benefit marine areas environmentally. However, a national marine park is not the case of providing environmental protection. The notion of a national marine park is the celebration of marine activities, thus protecting the interest of economic prosperity and marine tourism such as marine recreation and leisurely angling and fishing (Rutgar). At first glance, the notion of marine parks provides the notion of marine conservation, but it is quite different from a no-take zone, marine reserves, or special protection areas. In the case of marine parks, not all marine parks are created. For example, Plymouth in United Kingdom currently have various type of special interest groups and different protection zones (Marine protected Areas in the UK). Not all protection areas are created equal. The designated no-take zones in the United Kingdom are located at specific locations (Mzgoulton).

Marine Spatial Planning Upcoming Planning for the Sea United Kingdom

What is marine spatial planning? It is a policy discipline. In order to plan and regulate all human uses of the sea, EU commences a process that could gather all stakeholders together and coordinate among each other to make a collaborated decision on the application of marine resources. And right now UK is in the beginning stages of preparing a marine spatial planning. According to Marine Experts, the discussion of the planning would be on how a marine plan is needed for managing a Marine Park. As mentioned in earlier section, the current performance of marine management is not ideal. However, there are criticism rose against Marine Planning as a static map of large-scale land use blocks. With the simple and cruel delineation, the UK Sea is cut into several big chunks by its relative distance to the land (inshore/offshore) without any propositional suggestions. This act seems more in favor of protection over action.

“National parks are not for conservation of ecosystems or it’s not preservation of lifestyles, but it is celebrating things about those areas with recreation. We need marine planning for the sea, similarly to spatial planning for land.” Interviewee: Gillian Glegg | Head of Marine Sciences, Plymouth University

Conflicting Nautical Quays Fisher Community Lash Back Plymouth

As mention earlier in the case of Sutton Harbour, where majority of the docking space were dedicated to marina, fisher community in the area felt intimidated by the idea of Marine Park that promotes more tourism economic growth. Although the fishing community brings 13 million pounds per year to Plymouth economy and also provide fish throughout the entire UK, Marine Park would still pushing out the fishery business gradually and forcing Plymouth Fisheries to further relocate and lose its economic importance that built-up over many generations. The fisher community does not want that to happen because eventually with the growth of tourism economy under the promotion of Marine Park, fishers would have nowhere else to dock their boats. Therefore, with the feeling of left out in the future economy, fishermen raised protests in the city to advocate for their importance in Plymouth harbours. Currently, there are many ongoing protests and backlashes from the fishing communities and complains are associated with the lack of boating spaces for fishers to stay.

Intertidal Composition Geomorphology

03| Intertidal Composition In order to find a way to intervene the site and construct new landscape typology for the future economy of Plymouth, the natural formation of the estuarine environment needs to be well comprehended and integrated into the later design strategy. By carefully examining the built environment of the coast line and study the intertidal movement in the mudflat area along the entire estuary, the group were able to identify the essential forces that alters and shapes the land. Besides the nature, historical human settlement and infrastructure also reshapes the boundaries of the coastline and gradually change the composition of sediment placement and distribution over decades. All those traits are particularly intriguing for the group to further move on and speculations about those geomorphological processes could be justified for the scope of work. This chapter is about the preliminary study on the current coastal infrastructure and its association with geomorphological forces over long period of time.

Historical Development Coatal Evolvement Tamar Estuary

Historically, the town of Plymouth was situated along the pockets of mudflat landscape. Overtime, harbours and docks were built along the coast, and mudflat gradually transformed into a large port for docking ships and marine trades. Over the years, new development took place and the natural landscape of intertidal ground is gradually dissolving into the Tamar river.

Coastal Environment Hard Strcuture vs. Soft Structure Tamar Estuary

Through google satellite images of Plymouth, it was discovered that there are various types of practices exist along the coastal line of the city and surrounding towns. Those infrastructure are mostly still in use and mainly used for marine activities, particularly boat docking. However, the use of material and its form varies depending on the location. The group synthesized a catalogue of those different structures to study its potential application in project development.

Seawall Structure

The marina is constructed with reinforced concrete, gabions and boulders. It is does not only offer conventional coastal protection, but also harbour boats. But it require land construction and the construction is rather permanent than floating pontoon and less susceptible to erosion.

Floating Pontoon

Intertidal Mediations

Instead of land construction that might alter the natural coastal environment, the floating structure allows marina to grow overtime. Attaching to the land, the timber pontoon could be added as needed.

Tamar Estuary Ecology Formation and Condition Millbrook Creek

There are 106 estuaries in Great Britain (UK, excluding Northern Ireland) and the majority of the estuaries fall into five groups (below): (1) rias, or drowned river valleys, are short, deep and steep-sided with small river flows; (2) coastal plain estuaries are long and funnel-shaped with extensive intertidal zones; (3) bar-built estuaries are short and shallow with small river flows and tidal range, and are located along coasts with plentiful supplies of sediment; (4) embayed estuaries are large shoreline indentations with a relatively small amount of fresh water input; (5) fjords and fjards, which occur mainly in Scotland and represent drowned glacial valleys. Estuaries interact with the adjoining coast and can be a sediment source or sink: highly-stratified, short and ebb-dominant estuaries (i.e. bar built estuaries) are likely to be sediment sources, whereas partially-mixed, longer and flooddominant estuaries (i.e. coastal plain estuaries) and embayed estuaries tend to be sediment sinks (Burgess et al., 2002).

Nautical Translocation Territorial Formation

04| Nautical Translocation Plymouth is currently focusing its economy towards a marine tourist attraction. However, this have some negative implications to the entire sound and the city. As seen in the drawing in the left, the varying routes and potential port locations indicate a projected scenario of development. By developing more ports along the coast line of Plymouth, the harbour beings to exhibit an influx of activities that potentially thwarts the existing development of smaller industries such as the fishing community. This is due to the local member of parliament, Luke Pollard, advocating for a national marine park to be imposed along the greater sound of Plymouth. National marine park impact would include more of a tourist destination and advertisement for the city rather than a preservation of natural resources (Glegg). Heavy marine activities occur because the city operates within its marine environment as an opportunity to exploit natural resources (Cosgrove 49). Plymouth primarily navigates through its marine economy. However, Plymouth lacks the ability to rely on multiple economies. This project looks at alternatives to inform design policy to incorporate a diverse economy as discussed later in the chapter.

This leaves the existing fishing community pinched for space. In the enlargement drawing to the right, the red circles indicate the potential areas of development due to accessibility by road at the existing slipways. The drawing portrays a scenario in which development could occur throughout this region, but not all ports would be developed. The further explains the physical impacts along the estuaries and the sound due to dredging requirements to dock boats and facilities along coastlines. There is a need for a better management of the coast line exploitation.

LACK OF ALTERNATIVE ECONOMY

AVAILABLE NATURAL RESOURCES

New Economic Foundation -United Kingdom

Plymouth is focusing mainly on its tourism economy. In many cases of coastal communities, cities rely on their primary economic industry. Often, cities face a recession or economic crisis within their primary industry, thus struggling to find alternative generated income (Balata 10). Plymouth focuses heavily on their tourism economy. However, tourism economies are quite seasonal and fragile in many cases of low wage and part time employment opportunities only. As a result, Plymouth could struggle from diversifying its economy, leaving it unable to respond to a fluctuating economy. Plymouth needs to see its existing local industries as a shared coastal space for all economies to thrive to diversify its portfolio of generating income (Balata 12).

[Figure 4.1 - NEF Website]

[Figure 4.2 - Plymouth Fisher Vessels]

Diversifying economies in Plymouth means focusing on the existing fishing industry as a mode of production income. Additionally, existing recreational activities, include: waterskiing, yachting, jet skiing, kayaking, provide marine tourism economy in their marine environment. In New Economic Foundationâ&#x20AC;&#x2122;s Blue New Deal, the organization collaborates with local stakeholders such as fishers in East Sussex to voice their needs in the coastal community. The Blue New Deal strives to diversify many coastal communitiesâ&#x20AC;&#x2122; economic model. In the role of designers, the project is finding a way to inform decision making at a higher level to incorporate spatial qualities and economic prosperity.

Inform Design Policy Introduce precedence and techniques

The project explores the idea of designing spatial strategies to inform more decision making at the policy level that is typically not considered in the architectural scale. To inform decision making, the project researches on the precedence of marine tourism and production economies. In the case of fish production, the local fishing community and major fish market is an important role in the community. However, the project sees potential adjacencies of related development such as mariculture, fish hatcheries, fish stocking that can allow for collaboration of self-sufficient management. Additionally, there is a need for more vessel storage facilities due to influx of boating and recreational activities. Due to lack of space, the project sees opportunities in creating designated fish vessel storage and recreational vessel storage. The project allows for multiple programmatic uses along the coastal areas, thus creating a diverse design policy that informs diverse programmatic uses as discussed in the Blue New Deal.

Case Study | Tollesbury South East England | Environmental Agency Management

The case study research has expanded to the other side of the UK coastline, and the group looks at Tollesbury as an example in particular. Situated on the Essex coast at the mouth of the River Blackwater, the village of Tollesbury has a long history in celebrating both plough and sail activities. Its unique geographical location allows harvests from both land and sea. Today Tollesbury marina still functions as a main trading port for oysters. Woodrolfe Creek, one of the main creeks at Tollesbury, became the main sailing route for yachts and boats. With some minimal path construction, the surrounding saltmarshes were acting as trails for boat owners to reach their vessels. According to researches, this area is a nature reserved managed by the Environment Agency as a way of regulating cargo, boating industry, and mariculture and this site creates a diverse economy that responds to the landscape.

The project looks at varying precedence of fish production from the United Kingdom to international scale of fish farming. There are varying types of fish production ranging from high production at the cost quality to low production at higher quality. With the varying case studies of fish production, this allows an implementation of production that finds alternative ways of diversifying Plymouthâ&#x20AC;&#x2122;s mode of production.

United Kingdom is one of the leading fish farming industry in the European Union with highest yield in tonnage and third per value (Ellis). With United Kingdom yielding large quantities, various types of aquaculture are produced in the United Kingdom. This chapter examines the various types of aquaculture methodology to further understand the different kind of techniques that can be deployed on maritime boundaries to supplement the fishing industry. This could lead to not only production and consumption, but a subcategory of aquaculture emerges as hatcheries to replenish fish stock for the future of marine ecosystems and fishermen economy.

In this case, Marine Harvestâ&#x20AC;&#x2122;s salmon farms exhibited high concentration of diseased fish and a sea lice problem(Fraser). Because the fish are confined in small spaces, the salmon live stock suffers from various diseases and pest problems, which are typically solved by supplementing the fish with antibiotics and occasional pesticides to eliminate disease(Fraser).

Lerøy | Intensive Fish Farm Mariculture

In the case of Leroy, the company tries to focus on the production of fish in mass production, but to supplement the fish living conditions with symbiotic sea fauna and flora (Lerøy). Leroy focuses on the production of mussels to feed to fish, farm seaweed for wrasses or lumpfish spawning to eat sea lice, and create artificial reefs to eliminate the accumulation of concentrated fecal matter.

Aquapod | Semi-Extensive Fish Farm

Mobile Mariculture

As for the case of Aquapod, the approach utilises the broad area of the ocean as an advantage. The goal is to create mass production of fix, but confined fish produces negative impacts in one stagnant location. By producing throughout the vast ocean, the fish swims and moves with the structural unit. This creates an advantage of minimal maintenance and dispersing nutrients from the fish production (Earth Ocean Farms).

Greenwave | Semi-Intensive Fish Farm Mollusc Farming

Greenwave is a company founded in New York, United States, focusing on the production of sustainable polyculture. Most of their production consists of seaweed and seasonal shellfish (Greenwave). By doing so, this creates a seasonal rotating crop that allow a more resilient farming that can resist specific weathers in different seasons. In addition to the higher yield of production, the crops promote different food products on the dinner plate such as seaweed used as noodles. Seaweed and shellfish end up complimenting each other by filtering the sediments in the water together, thus creating a symbiotic relationship between the different crops(Greenwave).

Bioaqua | Extensive Fish Farm

Aquaponics

Extensive aquaculture focuses more on the quality of the fish within a smaller yield. In the case of Bioaqua, the farming focuses on aquaponic systems that allow the recirculation of water from the fish and the crops in a closed loop system. In addition, Bioaqua provides an aquaponics programme that allows local communities to take part of classes to either start micro production or commercial production(Bioaqua). As a result, the quality of the fish is sought after as oppose to the mass production of an intensive farm.

Veta La Plama | Extensive Fish Farm Eco-Sustainable Aquaculture

On the different scale spectrum, Veta La Palma provides an integrated ecological reserve that serves as a symbiotic relationship between the birds and farmed fish. The aquacultural system imitates a natural system without any added food for the fish, which allows a better cost management to the fish livestock. Veta La Palma proves to be the ideal example of fish farming without any supplemental additives to the livestock(Veta La Palma).

Vessel Storage Fishing boats, yacht vessels,and other recreational activities

Currently, there are various types of storage facilities. There are temporary pontoons, dry stack facilities, kayak storage facilities, and boat docking on shallow waters. In the trophic level of boating activities, many boats situated in marinas tend to block out waters, reducing the chance of wildlife to grow underneath the marinas. Dry stacking units, storage of boats on land, allows for the consolidation of boats stacked vertically. However, dry stacking systems require land development with local slipways and forklifts to bring boats to the waters.

05| Digital Articulation The project continues to explore the social conditions in which there is a lack of port space in Plymouth and examine the existing geomorphological conditions as an opportunity to change the way major actors utilizes the space in Plymouth. This chapter discusses the three digital techniques to inform design decisions, assist the understanding of existing geomorphological conditions, and simulate low tide conditions. The first tool focuses on the interactive and dynamic nature of javascript, Processing, as a way informing design decision by giving site constraints and path dependent routes to allow for future potential development along the coast. The second tool utilizes a flooding simulation tool, CAESAR, that examines the tide flooding conditions to better understand Plymouthâ&#x20AC;&#x2122;s intertidal areas. Finally, the third tool utilizes generative design, Grasshopper Firefly, to capture imagery of a physical water and sediment simulation to better inform long term change and development of existing creeks.

The tool explores the idea of marine path finding as a way of determining the added obstacles such as marine protected zones, port development, etc influencing the port passages along the Plymouth. To determine the tool’s set of rules and criteria, the utilizes A* path finding method, combined with with a grid of vectors and geographical information data. The goal of the tool is to determine the impact of natural resources along the Tamar estuary in Plymouth. By added obstacles, the tool determines the need of protecting Plymouth’s natural resources as a way of maintaining the resilience of the city.

Landscape Urbanism 2017-2018

This tool allows the user to understand the impacts of development through a simulated scenario of impacted passages. This allows an understanding of port development and the environmental impacts on the natural resources that many local communities rely on: marine tourism, fishing industry, seafood production (Balata 21).

Users’ Negotiation System | Graphical Interface

in the development of the tool, the tool attempts to utilize the interface as a way of visualization information to the stakeholder decision making options. The tool has the potential to allow major stakeholders to determine which coast line is availble for port development. Through the development of coastlines, the tool sees potential in providing opportunities and capacity constraints to allow for live feedback decision making for users. This provides opportunities such as development in intertidal areas and its capacity. The interface is a visualization in after effects to determine the potential of nautical negotiations.

After observing the mudflat of Tamar Estuary through site visit and satellite images, the group aims to understand the nature of this geomorphological process. The first step was to produce a prototypical model to understand the overall formation of the creek system by using simulation program. Several attempts and adjustments have been made to create the model look the most close to the actual landscape.

Besides the natural formation process, the group wanted to create two sets of tests: Barrier and Dredging. These are considered as the fundamental strategies in terms of introducing intervention. Another variables was to control the amount of water inlets on both side of the simulation model. That could offer more opportunities to compare and contrast the simulation results.

The selected simulation model represented the results of the variation tests. From those results, the group realized that the simulation program cannot accurately capture the geomorphological process in detail while running the tests was a time consuming process due to its large context. The group decides to narrow down the scope of work to a sectional study of the creek instead of a much larger scale.

From the result of the simulation, the group realized that the computer program has its limits in terms of the details.

However, the group get many useful information for setting up further experiment on the physical tank.

Creek Formation | Simulation Conclusion By using simulation program, one important thing the group discovered was that the geomorphological force that shaped the creek landscape was coming from the latent energy of tide water retained in the soil. During tide event, part of the tide water was absorbed and stored in the mudflat area. After tide retreat, most of the surface water came back immediately except parts of water retained in the soil. Then the water within the soil slowly release the water towards the lower ground. The flow formed a trace of water channel, which later result the creek.

The image to the right examines the dynamic shift of sediment movement, creating varying lines of water boundary. This experiment allowed us to understand the principles of that time that is interwoven into the design in chapter 7, Collective Creek Formations. As a result, the physical simulation was instrumental at the individual creek scale.

The physical simulation in the first image and diagram below examines the act of dredging and filling sediment on either side. This experiment looks at the varying effects of creating water ponds and land formations as a strategy to create programmatic uses of aquatic food production or additional boat storage facilities. By examining the varying programmatic uses, seen in chapter 8, in varying sediment levels and water depth conditions, the act of dredging and filling allowed the programs change based on the physical environment. This allowed for the following programs to occur through these actions: boat stacking, hatchery facilities, boating storage, recreation, etc. Dredging, filling, and barriers facilitated these programs to occur in the varying conditions.

To allow for variation, added single units allowed for a more diverse program. This allowed for the development of alternative industries to flourish in the intertidal mudflat conditions. As seen in the diagrams below, the experiment conducts angle and distance tests among the single unit intervention. The project hypothesizes the development of varying depths and conditions that allows for a more diverse program. The project sees development in a diverse landscape that informs alternative economies to rely on each other as a way of management (Balata 10).

Iterative Evaluation | Catalogue Single Unit - Angles

The simulations to the right looked at the dredging in either the front or back side from the water output location. From the varying experiments, many of the dredging behind the water source and filling in front of the water source diminished over time quickly. This was problematic because it would not allow for further program development. The project goal was to accumulate sediment over time to allow for land programs to flourish.

Intertidal Mediations

On the contrary, dredging in front of the water source allowed for potential boat programs to happen. However, the sediment accumulation would occur in the water ponds over a slow period. This was taken into consideration for the development of programs that would then eventually consolidate itself on land as a strategy for boat storage. Fish production became ideal at the filling location away from the water source. This allowed protection from the water source and a slower rate of sediment accumulation in the recently dredged areas.

At the rate of the single units are deployed, multiple units utilized understand the relationship between the distancing of the interventions that are used. The distance in the experiment include the following: 50mm, 100mm, 150mm, and 200mm. The distance begins to inform the shifting locations of sediments. Through the hypothesis of conducting multiple barriers, the project predicted the proximity of the barriers allow for clustering of sediment. However, the experiment showed the further placement of barriers allow for further displacement of the sediment.

In this chapter, the project examines the relationship between the intertidal areas with the opportunities posed in chapter 2. Intertidal areas discussed in chapter 3 looks at the existing conditions of creek formations and the development of local ports. Many of these develop through the maintenance of dredging and creating barrier marinas. In the case smaller marinas, intertidal areas utilize pontoons that dock itself to adjacent creeks and rivers to allow boat launching to occur in low tide conditions. Tributary agglomerations modify existing creeks to develop varying creek formations that allow for a diverse programmatic use.

Millbrook Intertidal Areas Activities along the mudflat areas Millbrook Creek

The project looks at Millbrook creekâ&#x20AC;&#x2122;s intertidal area. In the existing tide conditions, boats reside along the creek and sporadically all throughout the mudflats. This gives an opportunity of utilizing the geomorphological process of developing along the creek systems. The creeks are formed by the natural tide processes, thus creating creek formations over time. By utilizing this process, the individual creeks can be diverted to create a diverse intertidal landscape. The project continues to explore the idea of branching technique as shown in the technical report. Since there is a lack of space along the main harbour of Plymouth, development opportunities can occur within the intertidal zones. Currently in Plymouth, there are special protected areas along some parts of the intertidal zones (Marine Protected Areas in the UK). However, natural resources are part of a resilient coastal community. Many local economic sectors, such as marine tourism, fishing, and farm depend on natural resources (Balata 21). Through intertidal areas, creeks serve as a territory of natural resources.

Intertidal Mediations

The intertidal creeks serve as a vessel of space, mode of production, and ownership (Elden 810). Current stakeholders can take control of the intertidal areas as a way of managing their needs by taking territory as a role in the intertidal areas. By doing so, the project looks at the varying types of intertidal areas as a way of managing different type of territorial formations. Located in the Tamar Estuary, Millbrook creek indicates varying depths of tide levels and opportunity for many programs to flourish. Territory can be taken control and negotiated through the constraints of existing creeks. With the need of natural resources to sustain a marine city, development along creeks are limited to a capacity of existing numbers. The existing development are considered as an opportunity, but a constraint is kept in mind to inform a management of preservation of the natural environment that supplies the economic prosperity of the city. As a result, designing along creek systems allow for a negotiation of territorial decisions to inform marine spatial policy in a designerâ&#x20AC;&#x2122;s role.

Intertidal Mediations

The existing intertidal areas are composed of varying subtital, intertidal, and supratidal zones depending on the location of mudflat areas and depth. Through the strategy of planning and understanding of the physical conditions, programmatic areas are optimal at particular depths and conditions. This helps inform a way of interevening with existing creeks to create more diverse economic programs through the intertidal areas.

Model Explorations Tangible Experimentations

Model explorations examines the intersection between the tectonic formations of the intertidal areas through programmatic interventions. In the model below, existing intertidal mudflat areas are examined and then explore the dynamic shift of branching rivers. Through the conventions of adding barriers, dredging, and filling along the creeks as shown in chapter 5, territorial creeks form. The cnc model below informs the sediment accumulation through time as a way of responding to scenarios. In the models to the right, layered tide conditions are studied at different strata to understand the tide conditions at varying depths. The model was formed by setting an orthogonal grid to allow constraints along a creek study model. These series of models helped inform a more detailed approach on a creek system. This is then understood further in chapter 7.

Tributary Reconfigurations Modification to existing intertidal creeks Millbrook Creek

In the previous pages, the existing Millbrook Creek experiences constant influx of tide flows. Tide runs through its full cycle every 6 hours, creating a water table in the mudflat areas and discharging when over saturated. Through this process, the intertidal creeks form through series of time. In the scenario of economic fluctuations and events, creeks are used to generate a need for leisure and production. Plymouth’s intertidal creeks are the underutilized infrastructure, demystifying today’s definition of creek areas. Similar to the case in Paris’ Seine river as a public infrastructure, Plymouth’s creek system moves from the pastoral landscape to a modification of production and asset (Gandy 33). In the drawing below, the creek is no longer the pastoral landscape. The creek system of Plymouth serves as a multi-functional system that establishes benefit to the existing stakeholders through the modification of creek systems. In this case, diverting flow and collecting sediments

allow reconfiguration of physical creek form and diverse landscape. In the designerâ&#x20AC;&#x2122;s role, manipulating creek as a strategy allows for adjacent development such as towns and agricultural areas. The drawing below shows lighter blue of past development along the creek morphology. As the lines get darker and deeper in blue, the creek system grows and reaches a pinnacle opportunity for adjacent communities to take control of territorial creeks. This is a resource that allows development to decide spatially at a higher level to take control of their needs in diverse landscape characteristics.

Collective Creek Formations is a composition of challenging the conventional way of information design at a higher level. Today, land and sea are treated differently. However, sea and land have the same territory implications and spatial quality. The sea is simply diluted land with a fluid spatial quality (Steinberg 250). The project examines the blurring between land and water. Through design strategy at the architectural scale, creek formations are manipulated with vertical elements, merging the programmatic use on land and water. The chapter further discusses the development organizing through time as a response to future scenarios of coastal development.

Tectonic Manipulations Reconfiguring intertidal areas Tidal Creek

The project utilizes the physical simulation as seen in the chapter 5. The physical model is instrumental to see the physical impacts along the existing streams. In time, project takes into account scenarios of events that could occur. This is one sample scenario of development through time. Through various iterations, the project can understand the composition of sediment movements and low tide creek formations. In the drawing to the right, structures are place through time responding to the blurring between use on land and water. Programs storage facilities and seafood production industries merging with their adjacencies to create a diverse landscape.

Intertidal Mediations

This model is shown as a way of self-managing between many stakeholders and a way of marine management at the micro scale. In todayâ&#x20AC;&#x2122;s marine spatial planning, management has been developed through arbitrary lines and points (Steinberg 258). The marine space is constantly in flux and marine spatial planning does not respond to a constant changing landscape. As a result, the project maps out a scenario by responding with cooperative built structures that encompasses a diverse landscape with a diverse set of programs.

In the previous pages, generative analysis was conducted to understand the results of the physical simulation. The simulation results indicated certain depths and slope conditions, under 10%, that allowed for path development along the accumulated sediments. The matrix indicates set a depth and slope criteria that allowed for program placement constraints. With the given analysis, the project looked at three case studies in the images below. This includes mud dyke barriers, farming techniques, and barrier lane techniques. These case study systems are used as a way of organizing different programs to allow for resilience amongst the existing and new stakeholders. The programs are added for a diversity of production and tourism/recreation without eliminating the existing stakeholders.

Rather than competing with the different industries, marine management is spatialized in a coherent diversity. These programs respond to the economic impacts as alterative industries, shifting functionality throughout varying scenarios. This becomes a cooperative approach to change the role of policy making and inform how designers can take a role in the juxtaposition of policy and spatial design.

Adpative Nautical Management

Cartogenesis

08| Adaptive Nautical Management Adaptive nautical management sees opportunity in Plymouth. This chapter addresses the lack of fish boat docking and economic diversification through the development of intertidal areas. More space is allocated throughout Plymouth, but not exceeding a capacity within the existing creek system constraints. Through the development of intertidal creeks, vertical archetypes influence a way of managing intertidal cooperatives from the architectural scale to the regional scale of marine management. In the drawing to the left, the panel locates all existing slipways as potential of development along existing creek systems. The creek system is monitored and managed at a capacity since natural resources influences the success of marine tourism and production industry, as see in the economic scenario diagram, page 42. This coincides with New Economic Foundationâ&#x20AC;&#x2122;s philosophy of a diverse economy. However, in a designer role, decisions must be made at a higher level to inform design policy with spatial qualities.

Intertidal Mediations

In the drawing below, the intertidal areas depict the potential areas of port development that encompasses the capacity of production and vessel storage. Marine spatial planning should be defined by blurring the roles of land and sea as a way of accommodating the varying stakeholders. This becomes a negotiation and dynamic mapping to inform the need of a fluctuating landscape. In addition, economic events and social conflicts are things to consider marine management that is not considered in todayâ&#x20AC;&#x2122;s marine spatial planning. Marine spatial planning is not changing the economy directly, but a way to respond with spatial qualities that help inform cartographic dynamism. Plymouth needs a marine management plan that responds to its advent national marine park proposal. Intertidal creeks in Plymouth become a proposal that reacts as a territory

that serves the local stakeholders as owners to take control of space (Elden 804). Territory or territoriality is not confined to only land but the interface of land and water. The ownership of coastal areas plays a big role in Plymouth. Local fishers play a role in the estuary as much as the recreational activities and the boating activities. The role in which designers consult stakeholders provide a change on how intertidal areas can be altered as oppose to the conventional mudflat creeks of navigation and leisure. Intertidal areas are a territory of interest and provides opportunity for development within the capacity of natural resources relied on marine tourism and the fishing industry (Balata 21). A better marine management across the architectural scale and regional scale is a better resilient coastal community.

153

Intertidal Mediations

Epilogue The project focuses on the blurring between land and water. Existing development along Plymouth’s coast line exhibits marine real estate conflict, which hinders the development of existing fisher community. Because Plymouth is focusing on marine tourism, through an advertisement of a marine park, Plymouth relies on an unstable economy. The blurring between land and sea indicates the opportunities in Plymouth’s intertidal creek regions, creating management along creeks through intervening vertical archetypes. Plymouth needs a better marine management to negotiate between the varying stakeholders at a multiscale level, which is not considered in today’s marine spatial planning. The project sees marine spatial planning at the architectural, regional, and national level to inform design policy to consider the influx of water. Today’s cartography is composed of only lines and boundaries, which are static and does not respond to time: the fluctuations of economy, constant tide movements, and landscape processes. Intertidal mediations are interested in the negotiation of nautical activities that advocate for a diverse coastal community. A coastal community that can take back control in the marine environment as well as on land.
