RECHARGING BANGKOK A Climate Adaptive Vision for the Saen Saeb Canal Bangkok, Thailand

“Exploring the extensive roles of water infrastructure under extreme environmental conditions”

Thesis proposal aims to investigate an extensive role of Bangkok’s canal system that can potentially serve as a climate-adaptive and multifunctional infrastructure to help address the city’s environmental issues and to support the complex social needs. Together with municipal hydrological systems, the canals can mitigate flooding, land-subsidence and sea level rise while regaining lost cultural functions specific to Thai ways of living with water in both a contemporary context and future scenarios.

The investigation focuses on Saen Saeb canal as a primary study area which is historically one of the most important canals at the heart of downtown of Bangkok that connects Chao Phraya River and Bang Pakong River in Chachoengsao Province; it encompasses different transects of the capital city and context conditions form in the urban core to the periphery area. Relying on the fact that Bangkok is a delta city, this project has strategically turned the issues of flooding and land subsidence common in this kind of terrain into opportunities for social and cultural improvements by rethinking the relationship between canal and adjacent open spaces as flood mitigation tools and reconnects people to canal-scape, which can establish long-term strategies for the city to live with water. The study of the dynamic relationships between water, city, people and canal tectonics have been proposed as adaptive strategy that provides the diverse public realms, hydrological functions, and could be apply as rational principles applications for the other canals of the city.

Climate Adaptive Canals and Open Space Networks |Adaptation – Connection – Response| Design proposal focuses on the canal edge tectonics and adjacent open spaces along the canal in order to hold the water as monkey’s cheeks (water retention area) to mitigate flooding and increase the holding capacities. At the same time, design intervention enhances the public spaces for the city, which can be used in every day and flooding seasons by providing access and connections between canal edges and city area. The design strategies aim to transform the canals from linear engineering solution to multi-functional infrastructures in both hydrology and public realms for the city. T– behavior and perception to live with water not live by water.

Projection | Design Intervention Testing ideas Design intervention focuses on holding capacity, connectivity and extension spaces by using the adjacent open spaces along the canal to hold the water as monkey’s cheeks (water retention area) to mitigate flooding and reduce the limitation of canal capacities. At the same time, design intentions to enhance the public spaces for the city which can be used in every day and flooding seasons by providing access and connections between canal edges and city area.

The axon diagrams illustrate the variations of path types and multi-components that transform the rigid infrastructure to generate either ecology or holding more water combining with the in-land strategy. The primary concern of the intervention highlights on the existing conditions of the edge and fabric consists of existing elevation, edge condition, existing building and structure, and also the landowner. The variation of design applications would be applied to the specific site condition as a guideline for new infrastructures.

Urban Core Commercial District

For the urban core commercial district, the strategy applies to the existing inaccessible experimental field to be a recharge area for the city. The wetland terrace and folded back retention space will provide more room for water while enhancing the urban ecology for the city. In addition, the narrow strips along the other side of the canal covered by property fences will transform to promenade that improve the urban connectivity. In order to achieve, the negotiation process with the different landlords and stakeholders play a significant part of the implementation process to contribute the canal edges for the public.

For the mixed use and high-density urban area of Bangkok, most of areas are blocked by the property fences of the private properties that were mixed with the low-income community area along the canal side. The cantilever edge tectonic type is introduced to increase the flow rate to release the water out of the city through the wider canal profile. Combining with the retain operation by turning adjacent vacant lands to pocket sponge civic parks to hold the water during flood season and also benefit the neighborhood as a community space.

This pond is used as a kidney of the city by operating the air system to purify water from the Ladprao canal and drain into Saeb Saeb canal and direct to the Chao Phraya River by the great tunnel. The existing pond is covered by concrete edges and high-density informal residences; the proposal will turn the critical hydrologic site in to 100 floodable spaces by introduce the step wetland combined with the natural edges of the slope to increase the holding capacity of the pond and canal.

By reorganizing the community into the modular elevated buildings that can live with flood and help the city as flood motivational tools for the future development.

WAYU WIND FARM Design Proposal |25|

WAYU WIND FARM Master Plan for Innovative Sustainable Energy And Farming Huabong Distric, Nakorn Ratchasima.

Area: 793.1 acres

“Exploring the opportunity of waste land”

Located in Nakhon Ratchasima province, Northeast of Thailand, Wayu Wind Farm development project aims to enhance the leftover land (totally 793.1 acres), creating public benefits and ultimately yielding environmental, social and economical sustainability. The construction of 30 wind turbines and needed infrastructures, has caused numerous broken pieces of land with various sizes of borrow pits scattering over the area. The disconnectivity of patchesand corridors creates real challenges for ecological restoration within the site.

Thus, this project has strategically turned site limitations into opportunities to reclaim the land, optimize resources, and establish long-term sustainable agricultural system. With the concept “turning waste land to prosperous land”, three main strategies for land reclamation including hydrological planning, soil remediation and reforestation processes are proposed along with the 3-phase planning of physical structures and supported facilities for agricultural, research, producing and recreational activities. Practical strategies with step-bystep planning that could be real implemented to the site and specific techniques in each process are clarified. The proposed programs with cooperative activities do not only create a complete cycle of agriculture operational system but also help generating career and thereby income for the locals as well as find ways to share benefits back to the public.

The self-produced renewable energy becomes a resource for learning as well as supplying energy to agricultural and other activities within the area. (above) Innovative farmer market and greenhouse exhibition in commercial zone. (below)

Programming and Resource Management Programming and resource management aiming to be a prototypal project bringing prosperity to the locale, agricultural, human and renewable energy resources could be innovatively utilized to maximize benefits for both locals and public. Hence the concept, “Innovative Organic Wind Farm�, is initiated and applied to the proposed planning for physical constructions along with land reclamation processes. Various activities serving 4 groups of people comprise farmers, merchants, students and researchers, and visitors are organized into five zones: Commercial Zone, Recreation Zone, Research Center, Agricultural Zone and Production Unit. Commercial activities and tourist facilities are placed near the main southern entrance while research center is located near energy substation in the middle area. The production unit would be convenient for services via sub-entrance on the north. Besides, recreation area with learning trail and pavilions are along the stream including 21.75-acre devoted land as a waterfront public park. Existing road networks are still effective with additional service buses and bikeway for visitors.

The inserted programs and activities are cooperative, fulfilling a complete cycle of self-contained and selfsustained operational systems. For instances, knowledge and outcome from research and development projects on plant species can be directly applied to the real crops; agricultural products can be forwarded to production house and processing plant before being sold; and agricultural wastes can also be processed as pet food, fertilizer and fuel for biomass. Renewable energy produced from 30 wind-turbines and biomass will be sold while energy consumption within the site mainly derives from solar energy and wind energy from small wind turbines. The self-produced energy covers the operations of water pump, irrigation system and temperaturecontrolling system in the greenhouses.

Hydrological Planning Process The urgent task is to create water reservoirs – a stream corridor in the middle of the site together with numerous borrow pits need to be restored by improving their water-holding capacity. Hence clay and PVC liners will be applied on the surface of the stream and every pit, together with the construction of check dams every 2-meter height along the stream corridor. Additional plantations on the edges will help protecting soil moisture. While waiting for rainwater level to be increased in the second phase, soil humidity around the reservoirs will gradually increase and expectedly expand to the wider area (aquatic rings), allowing vegetation to grow naturally. The last phase is to build water channels along roadways, creating a complete network of irrigation systems.

Soil Remediation Process The first phase requires land leveling and grading due to its dimple surfaces and leftover building materials. To improve soil quality in the second phase, Sunn Hemp, a fast-growing green manure, will be planted in the area outside the predicted boundary of future forest.

During this period, the panoramic view of Sunn Hemp blooming can be promoted as a tourist attraction. The involvement of local labors would indirectly educate people on remediation technique. Once the soil quality is improved, choices of crop can be variety. Eventually, monoculture will turn to polyculture forests (green rings) around water resources. The following master plan is therefore designed in corresponding with the speculated future forests.

Reforestation Process Both natural and artificial reforestation techniques are adopted in this project. Young trees are highly-dense planted with additional fertilizer and mineral soil. The distribution of perennial plants among these young trees provides shading, protects soil moisture and adds leaf compost to the plants. Such technique will enable these trees to grow up-to 5-6 meters height. They are expectedly able to survive in natural condition within 3 years, follow by natural succession process within 10 years.

PAK PHANANG WIND PARK Master Planning : Long-term development and natural restoration.

Pak Phanang, Nakorn Sri Thammarat. Thailand.

Area: 49.5 Acres

“Exploring the coastal ecology”

This project is an initiation to create the first “Wind Park” in Thailand. Situated in Amphur Pak Phanang, Nakhon Sri Thammrat province, Thailand, the area covers 184.5 rai consisting of 4 wind turbines, with 125.2 rai for the designed area. The main idea of the project is to create public spaces for local people with limited budget and also help promoting tourism in the province.

This project aims to be an example for landscape planning and design with great respect to and understanding of nature. It also explicates that solutions to successfully integrate landscape with nature could be possible for designers with environmental concerns. Human can actually take advantages from the nature without destroying it, but at the same time should allow ecological systems to survive and be able to restore themselves naturally.

The master plan was divided into three phases.

The first phase (1-5 yr) is mainly for natural restoration process including reconnecting water system (destroyed after road construction) and creating break water made from a large pile of rocks to reduce sand losing. The second phase (5-10 yr) is to build up facilities in natural feature such as walkways, sand plaza, natural trail and temporary structure for community activities. The last phase occurred after natural systems are fully recovered (approx. 10-20 yr) community center, tourist pier,amphitheatre and hotel will be built for tourist attractions.

Emerging Network : Re-reading the openspaces

“ Exploring the urban systems and prototypical conditions”

The integration of patches and corridors connectivity and adaptation to urban scenarios Hartford is structured by the water system which is not only by the river but also by the upland water supply as a zone of protective land. Therefore, these created the large patches upland which is connected to the historical parks and all river as one system. From the observation, the connectivity of the parks and open spaces are all disconnected and unrelated in terms of physical connection and ecological connection. Hartford has a history of Olmsted era legacy of parks and also the area that they were not developed for people because it’s a low land flood zone. Consequently, the greenway master plan is not revised and performed as a connection for the city.

The project envisions to the point of connectivity either people and culture, ecological and hydrological flow for the city of Hartford by rereading open spaces in the way that re-shuffle the categories of the open spaces and what is the role of each to the city. In the way to combines the public park and recreational spaces, vegetated urban wild, flood zone and upland water supply as a protective zone as one interconnected by the water flow, and patches and corridors connectivity.

The analytical process of re-thinking the figure and ground in a new way to find new image of what it could be for open space in Hartford which is owned by different landlord and stakeholder such as city, MDC, school yard or some of the private land to emerge of new network from existing patches and corridors as all one new network.

TRANSFORMATION OF RISD FARM

SITE DYNAMIC AND OUTDOOR CLASS ROOM Tillinghast Farm Barrington, Rhode Island.

Design Principle Studio|Suzanne Mathew

“Exploring landscape ingredients and phenomena�

The final project from Design Principles studio, first core studio for Master of Landscape architecture program in Rhode Island School of Design. On the early period, the studio focuses on iteration process to understand the smallest things such as materials or landscape ingredients. The experimentation process through analogue and abstraction of material logic, site armature, soil structure, hydrological system and dynamic of the site to reveal the relationship, structure and also natural phenomena.

The project objective reveals the public area of Tillinghast Farm, RISD Farm, Barrington Rhode Island and transforms the site characteristic to the outdoor classrooms. The focused area represents the dynamic of the site and natural phenomena which naturally defines the space by the change of nature.

The site located on the edge between the forest and marshland. the project focus on the fluctuation of the tides which is changing around 7 feet range as diurnal tides to understand the relationship between topography, vegetation, and hydrological system. And also to measure the dynamic of salinity on the marshland and fresh moisture in the forest both in the ground and air. The project divides into the upland forest zone and tides zone.

The visitors will be leaded from the main parking space and common area to the arrival space of the classroom. The corten feature walls provide a transition space from the open lawn hill to the forest and also represent the corrosive process of fresh moisture on the walls. Inside the forest revels the fresh moisture changes between the edge and interior part of the forest and connect to the tides zone.

The main classroom on the tidal zone emphasizes the change of tide by landform which scooped down the land and integrated with amphitheater space. people who reach in this area can gather in the main classroom that contained 30 people for this activity on this lawn terrace and corten steel bench which is a threshold indicator between forest and marshland. The sub rooms around the berm create the different occupation area in different time of the day. And the last area is the riparian pool which is a freshwater pool and change to the blackish ecosystem on the tide period show the variation of the vegetations that change From spratina to high tide bush and phragmites in every foot of the topography. From the narrative of the design spaces reveal the relationship from the forest to the marshland and tides that people can learn and understand the special characters of RISD farm.

UNITY

STEPS TOWARDS A BLENDED FUTURE International Garden Competition 2020 Reford Garden, Québec, Canada.

“Exploring small intervention” Ideally situated in a forest, the Unity Steps allows visitors to enter the space from four separate undulating steps. The separate steps intertwine to become two paths, establishing distinct views of different environmental backgrounds and forming an interlocking platform and cascading steps to embrace the relationship of Man, Earth, and Water. One path engages views of St Lawrence River, the other engages with the forest, and both share views centered upon a mature tree. While the four steps breed different experiences for visitors, it ultimately brings people together in the act of mixing among the surrounding elements as visitors find respite at the central platform. The singular use of rebar steel speaks to solidifying the connections forged as visitors enter the space; which itself represents an essential element of structural foundations, an industry standard material for strength and integrity. This projects seeks to daylight the common material and permits it to naturally age with time. Visitors will journey through planting and be rewarded with views of a meadow blended into the platform and cascading steps once they reach the center.
