Pan-European ATLAS

The MA is engaged with the idea of territorial landscapes as the milieu for the development of a territorial practice. This practice is concerned on the one hand with the geomorphological formations of relevant landforms as its raw material and on the other with the actual cultural, political and economic forces that drive and choreograph what we call the social formations of these landforms. The understanding of these landforms as the primeval material is not solely the concern of a geologist or more specifically a geomorphologist (or any other scientist), i

neither conventional nor touristic. If the European territory is ever to gain the status of a coherent project, this demands that no process is regarded as too humble, that no mountain is thought more sublime than another, and that no stream is considered insufficiently picturesque. Landscape Urbanism will generate an atlas of possible territories as the basis of new forms of documenting the future of European environments.

The course seeks to explore how productive and natural formations can generate the basis of a pan-European project of territories which are neither generic nor iconic, Architectural Association

INTRODUCTION _ The British territorial crust is subsiding and global warming makes the southern England in siege. Facing to this invasive flooding, the short-term flooding protection tends to act upon a centralized territorial framework. From Cameron's speech, the Flood Re policy presents more capital distributed towards the centralized model, which might cause a huge loss in areas along the coastal communities. Our proposition seeks to revert the broken economical model with using tidal force as

A Pan-European Surge Atlas

instrument for transformation. Here flooding acts as an agent to influence the regional disparities, and potentiate decentralization. The project introduces a series of regulations to establish framework for independent economies. Instead of passive hard engineering, we choose to co-exist with flooding physically and economically. Activity on site, uses tidal creek as agent of change, space can be transformed in functional spaces such as hybrid agriculture, recreational land-

scape, aquaculture, etc. The land value is even boosted by flooding. As an alternative, the intervention seeks to mobilize territories effected by flooding, enabling local actor economies, and propose a territorial adjustment towards liberalization of territorial disparities caused by centralization.

Europe storm surges1

1.1 Where do surges occur? _ Storm surges can occur on almost any low lying coastline; practically any populated coast has some risk of a storm surge. However particularly high risk areas include The southern North Sea shoreline, where many highly populated areas lie close to th e coast just above, or even below, the mean sea level. The area has a large number of winter storms, leading to surges of over 50 cm around 10 times per year. The best known surge event in this region was the storm of January 1953, which killed and displaced thousands across the Netherlands, Belgium and the UK1.

1.2 Sources of Flooding S _ Recent severe flooding around the UK coast is a stark reminder of the risks presented by storm surges caused by a combination of high tides, winds and low pressure. The impacts on people, property and infrastructure, as recent events in Dawlish illustrate, can be significant. Storm surges, and their potential impacts, need to be understood by coastal managers, affected communities and all those with assets on the coastline. International flood and coastal engineering specialist HR Wallingford has developed SMART tide, a tool that can now be used to predict storm surges.2

The UK Environment Agency warned of "extreme danger to life and property" in parts of Norfolk, Suffolk, Kent and Essex and issued eight severe flood alerts. The Met Office meanwhile warned of gusts of up to 145km/h (90mph) for the Orkney and Shetland islands in Scotland.3

Further surges are expected to hit the English coast around Kent and London, but they will not coincide with high tide. The Thames Barrier is already being raised and the Thames has been declared all clear.

2.1 Insurance Policy _ The compensations scheme for private property damages, is regulated and supervised by Three bodies; The Environmental Agency, ABI and British Parliament. Association of British Insurers (ABI) represents around 300 insurance companies who together sell around 90% of all insurance products in the UK. Under the Statement of Principles, ABI member companies commit to make insurance available to domestic and small business, properties in areas that are not at a significant risk of flooding.

GOVERNANCE FUNDING

2.2 Governance funding _

Funding distribution diagram1

Furthermore, flooding defences funds are distributed within the centralized model, therefore the regeneration of coastal communities becomes an isolated problem. Most of the funding has been given London area, and it has kept growing for these years. Even in this case, Cameron announced that the funding towards flooding will decrease which may pose the coastal areas in siege. As security of coastal communities are dependent on central investments, experts have pointed out that reducing funding will be a very wrong decision.

2.5 Conventional Realignment Model (CRL) _ Current Realignment schemes model is sponsored for limited 5 years by the Central Government. Government has to pay a huge amount of compensations to rent the land so the construction can move on. And they are responsible for all the flooding loss during this period. In the long term Projection, this model presents a deficiency in terms its social and economical. We can imagine that hard engineering approach will finally be broken by the increasing sea level.

CRL TIDAL DEFENCE

2.6 Tidal Defences Scheme _ Flooding is a huge issue for Sandwich. Recently, they just began a tidal defences project to prevent the frequent menace from surge and high tide. The current defences in and around Sandwich only provide a 1 in 20 year standard of protection a 5 per cent chance in any one year that flooding will occur. At the Town Quay the standard of defence is lower still and flooding regularly occurs at this location. The scheme will also protect other key assets including Discovery Park, valuable infrastructure such as the main coastal access routes and key tourist and employment areas. The scheme will take 2..5years to construct and will cost approximately 21.7 million pounds. Architectural Association

Coastal Engineering Management Strategies

Soft engineering is the use of ecological principles and practices to reduce erosion and achieve the stabilization and safety of shorelines and the area surrounding rivers, while enhancing habitat, improving aesthetics, and saving money. 3Soft engineering is achieved by using vegetation and other materials to soften the land-water interface, thereby improving ecological features

Natural Coastal Principles of Operation Hard Engineering 2

Hard engineering can cause unintended environmental consequences, such as new erosion and altered sedimentation - sand deposition patterns, that are detrimental to the immediate human and natural environment or along down-coast locations and habitats. Examples of hard engineering are groynes - a wooden wall to prevent longshore drift - and sea walls that deflect waves. 4

2.8 Alternatives to CRL Netherlands _ As flooding has become a territorial issue, the solution should be more universal, in a larger scale. What is happening to UK has happened to Netherlands. Dutches has accumulated much experience in this area. This project is located in Noordward. This proposal has been approved and is in construction now. They decided to let the river flood the land where it used to be farming land. The state has prepared to buy up everything from the land owner

The Noodwaard is a polder of 45 kilometre squares, east of Dordrecht and north of Biesbosch. It was only converted to large-scale agricultural use in the 1970s, its rich soil and vast lots made it an attractive area for crop farmers. The polder is being opened up to river. Amazingly enough, while this forward looking innovation is happening, the landscape harks back to that of 1905.

According to landscape designer, Robbert de Koning, in this design the designers were trying to achieve a balance between new nature, new water and new ways of living and working. But it had to be robust as well; it had to remain functional as water leeds rise, in 50 or 100 years it really will look different: the emphasis will shift from agriculture to water.

Geologists take the long view, which can lead to some striking thoughts, and here is one: Britain is shrinking. As the waves crash onto the shores of this island, the rock is worn away or falls off in chunks, and, as the adage goes, they are not making land any more in Britain.

The Lydd Marshes are an area on the South Coast of England which lies between Folkestone in the East and Winchelsea in the west. The land used to be marsh land, but over time it has been changed to its current form. We would like to take you down the annals of time to about 10000 BC to see the changes brought about by a mixture of Man and Nature.

Lydd Marsh's sea defences have been greatly improved since the North Sea storm surge of 1953. Although there are sea defences along much of the coast, there is still some risk of flooding to the interior of Lydd Marsh owing to gaps in the sea defences and the complexities of internal drainage within the Marsh. Further improvements are being considered by the Environment Agency and other partners.

The coast is continually changing because of erosion, deposition and rising sea levels. By 2100, mean sea level around Lydd Marsh is expected to be 39-49 cm higher than it was in 1990 (source: UK Climate Impacts Programme).fishing.

The Isle of Sheppey is an island off the northern coast of Kent, England in the Thames Estuary, some 46 miles (74 km) to the east of London. It has an area of 36 square miles (93 km2). The island, like much of north Kent, comprises London Clay and is a plentiful source of fossils. The land mass referred to as Sheppey comprises three main islands: Sheppey, the Isle of Harty and the Isle of Elmley.

Social map of Sheppey 3

Satellite map of Sheppey 4

The Isle of Sheppey has had its share of emergencies: from the floods in 1953, which prompted construction of the sea defences, to the flood of 1978 and the cold snaps of 2010/11. The community has pulled together to cope with these severe weather events in the past. The coast is continually changing because of erosion, deposition and rising sea levels. By 2100, mean sea level on Sheppey is expected to be 39-49 cm higher

than it was in 1990 (source: UK Climate Impacts Programme). With a co-operative approach we could respond to coastal flooding, heatwave and cold snaps in a more organised way. One example is Minster-on-Sea Parish Council, which has developed a Community Emergency Plan to help with the local response in the event of severe weather emergencies. This experience could be shared across the island.

Social map of Littleampton 3

Satellite map of Littleampton 4

The Littlehampton peninsula, prior to the construction of sea defences in 1956, was one of the most rapidly eroding shorelines in the country. Protection of the cliffs at Littlehampton Bill from erosion has significantly reduced the supply of shingle to down-drift beaches.

There is no present demand for land reclamation to justify the high costs of advancing the line. Therefore, the. Preferred option is to hold the line by upgrading and extending the existing defences. Management operations must consider impacts on Units to east and west if drift is not maintained. A 1:150 year standard of defence is assumed appropriate.

Economic, social and recreation losses due to do-nothing or retreat the line are not acceptable. Erosion would be ongoing as the headland comprises low lying soft geology and is exposed to severe wave attack. Architectural Association

Focus on East Kent Peninsula

The 1,200 square kilometres area lies in the county of Kent and covers all or parts of the Ashford, Canterbury, Dover, Maidstone, Shepway, Swale and Thanet Districts. It is home to around half a million people. The Stour has five main tributaries draining the clay headwaters which meet in the large urban area of Ashford. The river then flows through rural chalk downlands into Canterbury where the channel is highly modified with flood defences, sluices, gates and mills controlling the flow. Below Canterbury, the river enters the tidally influenced Lower Stour area and flows through internationally significant wetland habitat areas of the Stodmarsh and Hacklinge Marshes, before flowing out into Pegwell Bay.

East Kent Peninsula Stour River

The Nailbourne and Petham Bourne are winterbournes that flow only once every few years. The mall streams around Whitstable and Herne Bay that make up the Oyster Coast Brooks drain a clay area, giving them flashy characteristics. In contrast, the Dour in Dover and the Pent in Folkestone have chalk catchments that respond slowly to rainfall, and are dominated by groundwater levels in the chalk. Over the years, floodplains have been modified creating a series of urban centres interspersed with agricultural areas important for flood storage. Flood storage reservoirs were completed in the

Upper Stour in the 1990s, offering protection for Ashford. Major changes have occurred over the last few centuries, the most significant being the draining of the Lower Stour which historically met the sea at Stourmouth. Changes in flow regime and the building of defences have modified this to valuable agricultural land. 83% of the area is agricultural land and some is amongst the most productive land in the country. There are a number of historically important sites throughout the catchment.

5.1 History in evolution _

Long time ago, during 150s AD, bewteen Isle of Thanet and the continent, there was a channel, Roman boats landed on Britain from the Point of Richborough fort today. From the channel, they can sail to London. Gradually, the land rises and the sea water falls down due to the beginning of a new ice age. The history of Sandwich the town begin can be dated back to 1028 that King Canute granted a charter to the monks of Christ Church, Canterbury to operate a ferry across the river and collect tolls.2

Sandwich was later to gain significantly from the skills brought to the town by many Flemish settlers, who were granted the right to settle by Queen Elizabeth I in 1560. From the map we can find today, we can see a evolution after 1700. The town keeps its size almost until the industry revolution begins where we can see the transportation network begins to grow.

After the second world war, a significant change takes place because of the establishment of Pfizer's site. This great pharmaceutical factory not only changes the landscape such as enlarge the lake Great Stour, but also facilitate a series of new residential between the industry and old town. Even an expansion of old town begins as some small settlements agglomerates in the south part.

5.2 The changing coastline of East Kent _ The coastline of East Kent has changed dramatically over the last two thousand years since the Roman Invasion. This explains the location of the early fortifications of Reculver and Richborough which were positioned to guard the north and south entrances to the Wantsum Channel. The Isle of Thanet, an island at that time was not defended. Over time the channel silted up, but it was still possible to sail to Canterbury in the 15th century. All that is now left is the River Stour

Map of Eastern Kent and the Isle of Thanet c.4th C. 5

Since Romano-British times there has been a gradual rise in sea-level which has had a marked effect on the coastline of Kent over the intervening two-thousand year period. On the north coast the tidal effects have eroded several hundred yards of the coastline away, including the northern ramparts of the Roman station at Reculver, whereas in the south, large amounts of alluvial deposits have built up over the years to create the Romney Marshes between Hythe and Rye, so that the once flourishing Roman port and Saxon Shore fort at Lympne now lies land-locked, almost 1 miles (2.4km) from the

sea. Eastern Kent has changed considerably since Roman-British times; the Wantsum Channel has completely silted up, connecting the Isle of Thanet to the mainland which has lost almost half of its coastline in the process - and the Claudian bridgehead port at Richborough now lies 2 miles (3.2km) from the sea.

The Royal Engineers constructed this enormous complex in short order. With British shipbuilding strained to the limits with the demands of war, great numbers of barges were constructed on site and were towed backwards and forwards to France where they distributed the supplies along the French canal system. 3

By early 1918, a train ferry berth and three train ferries had been constructed and huge quantities of material, including tanks and large guns, could be transported swiftly across to Calais. Almost all this infrastructure was dismantled after the end of WW1. Lake Noth created and dredged to disposed the remaining war ships. Architectural Association

coal and in 1896 Arthur Burr set up the Kent Coalfields Syndicate to buy the mineral rights and then commenced Shakespeare Colliery at the old tunnel workings.

Part of the problem was that the coal was down very deep, in thin undulating seams and was difficult to mine.

During the next 25 years the Kent coalfield came close to being abandoned on numerous occasions. From 1896 more than 45 test bores were carried out in east Kent and at least 10 collieries started yet it took 16 years of continual investment before any commercial coal was raised to the surface. 1

The remainder of the coal had industrial infrastructure, was dismantled along the years, and old railways has returned to nature and agriculture with only a few isolated earthworks remaining although much of the course is still visible as a 'crop mark' across fields in aerial photographs.

PFIZER &SANDWICH 5.6 Interview Andy Rochetti, Estates Manager of Discovery Park _

Great stour and water treatment The Great Stour is a big saline lagoon on the site of Pfizer. It was small as the historical map shows. After the establish of Pfizer, they enlarged the lake and make it in the use of pharmaceutical manufacture use. And the same time, to reduce the impact of environment, the site itself has a waste water treatment system. The purified water won't release into nature river course, but recycle back to great stour again.

Donation of Nature Reserve The Monks Wall Nature Reserve, was owned by Pfizer, which covers 69 acres. The company decided to lease it to Sandwich Town Council _ without charge. It is used for educational visits by local schools and colleges. Mr. Rochetti

According to Dr Terence Clifford-Amos, mayor of Sandwich Town Council, said that it was "highly important as a place for migratory and non-migratory bird life and for grazing and for flora and various types of fauna".2 Donation of Pfizer - Monks Wall Nature Reserve

Sludge The intertidal land contains high salinity from sea which makes the soil barren. Historically, the soil of grazing fields around Pfizer's site are getting more and more rich remarkably, thanks to the by-product of manufacture, which is a sort of biodegradable sludge.

Water gate, dyke and defenses In terms of flooding management, Pfizer has done some effort to prevent it. Firstly, they set up two gates along the Stour river to let the higher water level inside the site can be released into river once the surface runoff threatens. Secondly, to prevent river tide, they set up a dyke along the river. Thirdly, the construction of tidal defenses which is taking place in Sandwich town is sponsored by Pfizer. Water gate and dyke

Workforces Pfizer is the most important industry of Sandwich. Populations of workers in Pfizer has reached 9000. The departure has seriously affected the town. Pfizer is the biggest employer in this area. According a report from BBC in 2011, "If companies that are ready to take over the site are not found soon, then the 2,400 remaining Pfizer employees will quickly leave the area. Another 1,700 contractors, who work on the site, as technicians and support staff, will also lose their jobs. Along with cleaners, caterers, security staff, and parallel public sector redundancies, the total loss of jobs in the area could be 5,000, according to local MPs." 3

NEW ENERGY STRATEGY

5.7.1 Richborough powerstation History The power station was built by the Central Electricity Generating Board in the late 1950s and early 1960s, and entered service in 1962 as a 342MW coal-fired station, using coal from Kent and other coalfields. It was converted to burn oil in 1971,and further converted in 1989 to burn a proprietary oil and water emulsion called Orimulsion, imported from Venezuela through Port Richborough. The site was also chosen as the site for an experimental 1MW wind turbine, which was at that time the largest ever installed in the UK,with permission given in 1987, and the turbine becoming live in 1989. After growing concerns over the environmental effects of the Orimulsion fuel in the main power station,court action was taken in two separate actions,[8] with both cases settled out of court.the 360MW station ceased generating in 1996.

Demolition Following the plant closure, the majority of the equipment was removed during a strip out programme, which also saw the demolition of a number of the buildings, leaving only a few outbuildings, the office block and the landmark cooling towers and chimney standing. In controlled blasts, the three 97m cooling towers and a single 127m chimney stack were demolished on 11 March 2012. Some locals had campaigned to keep the towers, saying they formed part of the historical landscape and were used as a navigation point by boats wanting to enter the mouth of the river stour known to have a narrow channel of useful depth.

Future The current owner of the site, BFL Management Ltd, plan to bring the site back into use as a 750 million pounds green energy park. The national grid interconnector from the original power station is still in place, and is now the grid link for the offshore Thanet Wind Farm. There are additional plans to create additional recycling and green energy facilities on site, including an anaerobic digester, a waste processing plant, a biomass combined heat and power generator, a pyrolysis plant and a peak demand 30MW diesel generator. When fully operational, the park could provide up to 1,400MW of power, employing 100 full-time equivalent, with up to 500 jobs in the construction phase. [10] National Grid plans to use part of the site for a new interconnector with Belgium. A 1000MW High Voltage Direct Current (HVDC) 130 km undersea link with the Belgium transmission operator, Elia, would allow power to flow in both directions. This would be the third link from the UK National Grid to Europe, the others being the Britned 1000MW link to the Neitherlands commissioned in 2011 and the IFA 2000MW link to France commissioned in 1986. The link should be in operation in 2018. 1

5.7.2 CHP Biomass on Discovery Park Estover Energy is proposing to build a local scale biomass Combined Heat & Power (CHP) plant to provide renewable heat and electricity to Discovery Park, one of Europe's leading Science and Technology parks, near Sandwich in Kent. The CHP plant will also supply low carbon electricity to the grid. The biomass plant will use locally sourced wood fuel to generate sustainable heat and power for Discovery Park, significantly reducing its energy costs, carbon footprint and reliance on imported fuel. Electricity that Discovery Park does not use day-to-day will be exported to the National Grid. This supports UK national targets to generate 15% of its energy demand from renewable sources by 2020. 2 Energy revolutioin _

6.2 OUTSKIRTS _ This comprises two sub-groups: cultivated arable and horticulture land, and grazing pasture. Arable and Horticulture land - comprises extensively cultivated land, at times with large areas of bare earth, and a highly variable seasonal vegetation cover. It supports predominantly a mix of vegetable crops and arable, with some soft fruit production in the south east of the study area. Grazing Pasture land - comprises a varied mix of improved and semi-improved natural rough grazing marsh/pasture. These areas generally share a common origin historically as areas of coastal and floodplain grazing marsh, and as a result are characterised generally by high ground water levels and the presence of seasonal or permanent surface water-filled hollows or ponds, and wetland plant species such as reeds and sedges. Enclosures are defined by linear boundary drainage ditches, which maintain their water levels, and contain standing brackish or fresh water.

This vegetation type was historically much more widespread throughout the study area, but improved land drainage and intensification and changes in farming practices has resulted in much of the inland areas becoming drier, and these now demonstrate contrasting vegetation properties. As a result many of these areas are now within the agricultural classification Grazing Pasture.

recognised as an evidence of tide dominant estuary. The tide range is very dramatic these years, it has arrived 4 meters. So a series of salt lagoon, grazing marshes have been formed even they are located far from seaside. We have also discovered the river network is widely existed on the valley where the adja-

cent settlements has suffered flooding during more and more frequently. Farmers have to prepare sand bags near their home to fight against a sudden flooding. Based on those observation, we decide to use tide simulation tools to test the worst scenario .

FLOODING STORAGE

8.1 Flooding reservoir _ A reservoir is a natural or artificial lake, storage pond, or impoundments from a dam which is used to store water. Reservoirs may be created in river valleys by the construction of a dam or may be built by excavation in the ground or by conventional construction techniques such as brickwork or cast concrete. Reservoir can help flood control also known as an "attenuation" or "balancing" reservoir, flood control reservoirs collect water at times of very high rainfall, then release it slowly over the course of the following weeks or months.7

Informed by this simulation, we understand the flooding reservoir is effect on site and probably can be used as a macros-cope strategy, meaning, we can create reservoirs and let the land be flooded with an intentional planning. So water can be introduced to where it is needed. With an understanding of the land-use and the effect , designers can decide the area to be flooded and make the most advantage from it.

They are small-scale landforms with a low hydrodynamic energy environment without significant wave action or strong current action.

Formation mechanism3

Tidal cycles repeat every day twice, the force excavates the land. The water goes up and down. When water goes up, it begins to resolve the sediments and they are carried in the water. When the water goes back, sediments follow the ebb and are brought to the sea. That's why the tidal forces cause an erosion.

The simulation on the top sector shows a sequence of change of the erosion. We can grab an important message from it, which is that the clean branch at the beginning will branch and the course will be widen with exposing it to tidal force.

The accumulation in time leaves a special erosion pattern. This dentritic landscape is called tidal creek.

MECHANISM 8.2 Factors of land formation _

Many researchers have studied about hydrology, hydraulics and geomorphology in tidal environment. However, the dominant parameter for developing tidal creek remains unclear because these complex network system is the result of long term morhodynamic process. Recently, numerical computations also have been performed to simulate morphological evolution of salt marsh, including development of tidal creek network, by using simplified model (Alpaos et al. 2005) and physically based model (Masuya et al. 2007). In these studies, it is shown that physically-based model can reproduce channel network configuration qualitatively. With this numerical approach, Toshiki Iwasaki and his team made a series of tests. Basically the geological and hydrological charactes case are based on their site, Notsuke marsh. A comparison of different inlet remarkably reveals to us the key fact to produce a tidal creek. The setting and parameters are on the table below

Case 1-1 0 day, 10 day and 100 day _

Case1-2 100 day _

Case 1-1 used a meandering channel as the initial bed shape, as shown in fig.2, after 10 days and 100 days, a dentritic network has been developed. Besides, initial meandering channel migrates toward land due to flow associated with flood phase. From comparison between this result and network configuration in Figure 1, it is found that a model can reproduce channel network which has like actual field characteristics of complex and meandering. With personal observation, the meandering channel caused a erosion on turning point, where the water course begins to branch. According to the researcher, this result suggests that ebb flow with phase lag is key factor for development of tidal channel network. â&#x20AC;&#x153; This flow migrates the channel and transports sediment to upstream side. It indicates that the flood flow also affects network extension. The result implied that the ebb and flood flow have a different role for geometric change of salt marsh, including formation of channel network. 100 days as a time scale too, the final network is less complicated comparing to case 1. Researchers gave an explanation as This results suggest that the slope of marsh surface is important for channeling process in tidal environments. In sloping bed condition, flooded water on tidal marsh can be drained with decreasing of water level, because the platform slopes from landward to seaward. This effect decreases shallow flow with phase lag which contributes to developing channel network. Moreover, flow velocity associated with flood phase is also reduced by bed gradient which oppose flow direction. The result indicates that the marsh slope restricts the development of channel network. The initial bed shape settings of Case 2 is a random inlet on flat marsh.The result shows as fig.5 below, showing three main meandering and branching channels form from downstream end. The network is less sophisticated than all the Case1 tests. Researchers didnâ&#x20AC;&#x2122; t compare results between two cases. From a personal perspective, a more regular and explicit landform should be conducted from the beginning. To sum up, firstly, the tide in meandering channel with different velocities transport sediments result in erosion and deposition at different parts which can trigger a tidal creek evolution. Secondly, a slope from seaward to landward will be restricted to the network formation. The paper has also listed out some other factors affecting the formation, such as vegetation, ebb phase and flood phase, etc. Regarding the intervention of project, we are mainly focus on the topographical influence on this mechanism.

After examining many studies about morphogenesis of tidal channel network from W. Vandenbruwaene , P. Meire, S. Temmerman, they all agree that after a period of time most of models are considered to be frozen, with only minor changes in further development. Consequently they decided to research this with a newly constructed tidal marsh (Scheldt estuary, Belgium), which measure spontaneous formation and evolution of a tidal channel network during a period of 4 years using high-accuracy topographic, in conjunction with survey of a temporal resolution of 1 year at high spatial resolution considering all channels deeper than 0.1 m. To construct a marsh ecosystem in the low-elevation polder by introducing a controlled reduced tide (CRT), 3 major adaptations were necessary: (1) building a ring dyke to protect the surrounding land from flooding (Fig. 6A), (2) lowering the river dyke for temporary storage of storm surge water, and (3) constructing an inlet (high in the river dyke) and an outlet sluice (low in the river dyke) to introduce the daily tidal regime (Fig. 6B). By using a high inlet and a low outlet, the spring-neap variations in tidal flooding frequency and height were successfully installed in the polder, but with a clear longer still water phase as in the estuary (Fig. 6C) . The result is shown as fig.7 and Fig.8. The initial ditches can be clearly seen on fig.7A. After 4 years, some new creeks formed. â&#x20AC;? After two years, the cross-sectional area of the former ditches was already in equilibrium with the corresponding tidal discharge. By the third year, the mainstream lengths and the channel drainage densities of smaller watersheds attained an equilibrium with the corresponding tidal discharges, demonstrating the rapid headward growth of newly formed channels and tributary channel formation near the channel heads. Conclusion Conclusion is made from this experiment, New channels preferably developed at low elevation sites because flood and ebb flows concentrated towards these low elevated zones, and because relatively thick deposits of fresh unconsolidated sediments enabled fast channel incision there. Within the low elevation zone, vegetation had no significant influence on the channel extension.â&#x20AC;?

8.3 How to provoke the development _ The pressure will be concentrated on the very end of course, if there is no sub branch to share the pressure, it will keep growing without control and it is likely to cause a flood once the water level keeps rising. By building dyke and dredging the creek, can make the other parts at river course to share the water pressure. So a more sophisticated system can stabilize the fluctuated tide and offers a sponge effect to hold the flooding water and reduce the impact from surge.

COURTYARD STUDY

9.2.3 Courtyard study and town service _ The service community inside a building groups is a form which can be seen in many types of land use. The dimension varies a lot. Here we focus on a medium size group, college courtyard , as the basic point to understand the composition of service community. The conclusion is made from the research of Cambridge. This can be used for not only the college, but also can possibly applicable for all medium size public building with around 1000 people, such as supermarket, government building, cultural complex etc.

9.2.4 Mixed farming study _

MIXED FARMING STUDY

Mixed farming is an agrarian system that mixes arable farming with the raising of livestock. When on a farm along-with crop production, some other agriculture based practice like poultry, dairy farming or bee keeping etc. is adopted, then this system of farming is known as mixed farming. It is the dominant system in Europe and now in parts of India, where most farms have a mixture of fields and pastures. The referential case is in South Africa with a mixture of agricultural activities and land formation. The economical structure is stable and successful. Architectural Association

CATALOGUE EVOLUTION

9.3 Catalogue of Evolution _ All of these prototypes also have a time-based relationship. By implementing various intervention, we are able to conduct a mudflat to transform differently. We roughly separate the whole phasing guideline into 3 parts on the time-line. For the first 5 years, it can be triggered by governmental investment. It can be the compensation for a realignment scheme as we stated in the second chapter. 127

Then smaller stakeholders will maintain it or give it some more interventions. The labor intensity is relatively less than the first 5 years which means these interventions are manageable by smaller group. Later some more complex scenarios are going to be developed. It has to be governmental project again as it requires more professional planning and construction.

Most have been reclaimed from the sea by drainage and embankments. A network of ditches, for much of the year containing standing brackish or fresh water, allows water levels to be manipulated and the marshes to be kept wet during the drier months. As their name implies, most coastal marshes are grazed, although some are cut for hay or silage.

Grazing Pasture land - comprises a varied mix of improved and semi-improved natural rough grazing marsh/pasture. These areas generally share a common origin historically as areas of coastal and floodplain grazing marsh, and as a result are characterised generally by high ground water levels and the presence of seasonal or permanent surface water-filled hollows or ponds, and wetland plant species such as reeds and sedges. Enclosures are defined by linear boundary drainage ditches, which maintain their water levels, and contain standing brackish fresh water.

CONCLUSION 15.0 Coastal futures _ Coastal Futures examines flooding territories, challenging the conventional realignment schemes, and focuses on the development of a territorial instrumentation, as a mean to address territorial disparities caused by centralized governance in UK. The project focuses of 5 different scales, each scale addresses multiple policies; climate change at a European scale, Policies and Strategies towards flooding in UK at a National Scale, The centralized governance model at a Regional Scale, and Economical Territorial entities at a Local Scale. In parallel the project has also developed a Technical catalogue as a guide to examine the Tidal Geoformological Forces for the regeneration of multiple economies. At a European Scale, due to the global warming, the sea level is rising. Storm surges in the southern North Sea pose a complex, persistent and growing threat to the surrounding coastline of North West Europe. United Kingdom is one of the countries that is more affected by the Surge Phenomenon, with more than a million properties at risk from sea and tidal flooding, corresponding to roughly five percent of the population. The compensation Scheme for private property damages is regulated strictly by three main bodies; The Environmental Agency, The association of British Insurers and the British Parliament. In 2015 the policy Flood Re will exclude insurance compensation from properties built on high flooding risk areas. These restrictive insurance policies will completely immobilize the territorial profitability of coastal communities. Furthermore, flooding defences funds are distributed within the centralized governance model, therefore the regeneration of coastal communities becomes an isolated problem. In the UK the largest flooding prone areas are found at the south east coast. During the recent winter of December 2013, the Southern Coast of England was widely invaded by flooding. The proposed realignment schemes funded by the central government are being part of the agenda to compensate damages, but communities at the south east coast are not within the first line of priority. The current model for realignment schemes is initially sponsored by the Central Government, the five year implementation programme suffers a deficiency for the long term projection in terms of its and social and economical retribution. The objectivity of the project acknowledges the coastline is losing land, and seeks for the optimal resources to maximize the territorial potential. Conventionally hard engineering performs as a line for ownership patterns, our approach allows flooding in a controlled way to provoke territorial transformations in time. Time is an important element towards the understanding and development of the project, the methodology aims to redefine the territorial boundary of sea and land in time. The project framework is based on three strategic aspects; firstly on a five year resource programme sponsored by the Central Government that becomes an anchor point for further transformations. Second, uses the constant tidal force to enable the creation of regeneration of self sufficient economical entities that can independently evolve in time, and it enables the coexistence between self multiplying economical entities. At a territorial level, the research operates thought Cartography to challenge the idea of the coast as a dividing line, particularly on the East Kent Peninsula were the coastal boundary has always been unstable since Roman Period 150BC, when landscape was more intricate than present with larger bays and estuaries. At a Local and Regional level, the methodology operates through the implementation of tidal simulations tools that create a `Catalogue' of time-based Land Transformations. The Catalogue informs a territorial engine 'Cartogenesis' that triggers the evolution self sufficient economical entities. The South East Coastal territories at risk of flooding can be transformed through the 'Catalogue' methodology, Each territorial transformation responds independently for each site condition, therefore the resultant Cartography impacts on the conventional image of UK map. Coastal Futures proposes a territorial adaptation to activate and mobilize coastal territories affected by flooding, enabling self sufficient economical entities to create adjustments towards the liberalization of territorial disparities caused by centralization.
