Introduction
The Delta Interventions theme for this year is landscapes of coexistence, which focuses on transitional spaces, infrastructure and power in the North Sea. Within the context of the North Sea, I depicted the Netherlands as a battleground, with the Dutch in a constant struggle against it. Thus, the project is an interpretation of the long-standing tradition of the Dutch battle against water. This led me to choosing my site, the Wadden Sea, where this battle between the land and the sea is at its most extreme. The varied research presented here gives an insight into the dynamic and extraordinary morphology of this landscape. The project traces the myth of “making new land” by investigating four major themes adopted from a recent publication ‘Sweet and Salt: The Water and The Dutch’. These four themes are perceived as a thematic backbone of the Dutch waterscapes. Therefore, the intention was to analyze the Wadden Sea and the island of Schiermonnikoog by using the themes: conflict, concord, profit and pleasure. After the investigation of these four themes, the motive here is to project them into the future by using the scenario method. This scenario envisions a future when the West Frisian island of Schiermonnikoog is left to nature and risks slowly disappears into the currents of the North Sea. The design intervention narrates a new myth: “guarding the water” by using the typology of a fort.

The North Sea: The Dutch and the German Coast
North Sea Field Trip with Delta Intervention Studio October 2017 The group’s focus is the 600km long strip of North Sea coast in Germany and the Northern part of the Netherlands. What make this part of the North Sea special and certainly interesting for us is its natural conditions of the Wadden Sea, the Frisian Islands and the related natural dynamics. This special part of the North Sea is strongly influenced by the tides and offers one of the biggest protected UNESCO habitats in the whole world with a rich flora and fauna. Water currents and the sediment streams are forming this naturally very vulnerable landscape and are creating dynamic interaction of water and ‘moving’ land.More extreme weather events, stronger water currents, heavier waves and especially the rising sea water level threaten this necessary sediments dynamics. The sea demands more space to expand and to refine the natural balance.This balance is difficult to maintain, be-
cause the territory is occupied with farming land, urbanization, flood protection systems and energy facilities. Static human systems, like dikes, walls and buildings, act as a buffer and protection. These processes are determined by the loss of salty marshlands as well as by the distinction of numerous types of animals. On the one hand the static human elements are threatening the natural system, on the other hand is flooding protection essential for the hinterland of the German and Dutch North Sea coast, because the coast territory is mostly under sea level or slightly above. Different Future scenarios are stating that huge parts of the countries hinterland, including the major cities, would be flooded. Also the human system is threatened by these conditions. The rising

sea level will gradually increase the amount of salt in the farmlands ground. Farmers are loosing their traditional way of growing plants and need to reconsider new ways of farming. Also human leisure areas might be lost and flooded as well as the tourism industry might suffer from it.
By giving space to the water certain function on land might be replaced and transformed. Algae production can be used for example as a resource for energy and food as well as the natural system is benefiting from it. An additional positive effect might be the creation of more leisure areas and attractive sites for tourists.
Future scenarios of climate change will threaten both the natural system and the human system. They need be interrelated rather than existing next to each other. Our vision of the future coastal edge is of an adaptive and dynamic nature, which responds to the dynamics of the sea and predicted future scenarios. The key element is ‘building and working with nature’; maintaining the natural conditions; its systems and the flora and fauna of the North Sea, by giving the water more
Another challenge might be of strategically nature. By giving more space to the water the actual Sea might become even more occupied by production facilities and infrastructure than it is today. Even if we
10
North Sea Field Trip Sketches, November 2017 find a way to balance human and natural demands and needs, managing different interests of the surrounding countries need to be taken in to account, for example using the idea of macro regional strategies and transnational agreements.The overall aim is that both the natural system and the human system are mutually benefiting from each other. The key idea is, that ‘building with nature’ means not just the increase the adaptiveness of a system but to ‘delegate back to the biosphere, what she does well […]’ (Saskia Sassen, A Third Space: Neither Fully Urban nor Fully of the Biosphere’).

EVENTS HAPPENING IN THE NORTH SEA: A SECTIONAL TIME STUDY Wadden sea is a sediment basin due to corresponding sea and river flows. Also, it has tidal movements on the surface which forms a tidal base on the sea floor and later causes the salt marsches to grow with its movement. And there is many more events happening in different frequences. All these natural and infrastructural events happening on the grid terrain that we defined on the first image. We tried to symbolise the continuity of these simultaneous changes with a time capsule. In every piece of these capsule, a diverse event is happening. And the overlap of all of these events defined the natural and cultural landscape of the Wadden Sea

CIVIL GUARDS OF THE WADDDEN SEA The terrain which has defined in the first image is placed as a terrain which is a palimphest of diverse events. This terrain is dynamic and regulates the border conditions between dynamic north sea and static coastal line in contrast. The two civil guards in the image represents the laws and policies in terms of protecting the wadden see and respectively the north sea. But in contrast to original, because normally civil guards were protecting the land against ivasions especially against the Spanish invasions, by putting these guards on to sea, in front of the wadden sea border we tried to highlight a new position is to be taken in terms of protecting and regulating the borders in the North Sea.

The large coherent system of Wadden Sea tidal flats is protected towards the open North Sea by a long chain of barrier islands of different geological origin. In the innermost part of the German Bight, characterized by macrotidal conditions (tidal range >3.5 m), open tidal flats and ephemeral sand bank islands occur. Dashed lines indicate mean tidal ranges. Highly dynamic islands: Rottumeroog (1), Kachelotplate (2), Mellum (3), Scharhörn / Nigehörn (4), Trischen (5), Norderoogsand (6), Kjeldsand (7).

Wadden Sea is an ebb tidal delta, where the sediment sharing system causes the Wadden islands to demonstrate a highly dynamic morphological pattern. According to Hellwig and Stock “Large scale examples of continuous geological processes and morphological interactions are on public view in the Wadden Sea. Among the most spectacular are the creation, continual shifting and changing, and ultimate disappearance of many of the region’s uninhabited natural islands, along with all the biota they support.” They also remark that the highest mean shifting rates are reported from The Netherlands . This lead me to map the morphological transformations of the territory in three different scales, with each scale posing different problems. The first scale is the Wadden Sea Area (from The Netherlands as the westernmost extremity to Denmark as the northernmost). The second scale is the West Frisian Islands and Northern Netherlands, with the third scale being the island Schiermonnikoog.
Scale 1
SCALE I
3. Moving Islands Large amounts of the Wadden islands are moving, causing them to demonstrate a highly dynamic morphological pattern. The direction of their movements is changing in time and their moving rates are proving to vary differently. Importantly, the highest mean shifting rates are reported from the Netherlands. The current land reclamation policies of the Netherlands are against mobilisation of the islands of Texel, Vlieland, Ameland, Terschelling and Schiermonnikoog. For that purpose, sand nourishment on the beaches, dikes and sand drift dikes are implemented against the dynamic nature of the islands. But in the future, especially with the contribution of the sea level rise, these implementations may not be enough to keep the islands in their static state.
WEST FRISIAN ISLANDS & NORTHERN NETHERLANDS 1. Coastal Squeeze In the current state, the densification of urban, industrial and agricultural areas on the coast threaten this naturally very vulnerable landscape with coastal squeeze. Coastal squeeze is another threat to Wadden’s unique habitat than sea level rise and gas extraction. Unlike the sea level rise and the gas extraction, the coastal squeeze is a problem developed over centuries during the Holocene development of the Northern Netherlands. Starting form 500 BC, the ebb-tidal delta of the Wadden Sea was getting smaller during centuries. And finally, with the effect of the land reclamation processes it is taken todays shape. 2. Drought & Salination Threat Climate change, land subsidence and new water demands may lead to droughts in the Netherlands, despite it being a relatively wet country. Additionally, climate change leads to salination of the fresh water as well, which may lead shortage of fresh water for houses, agriculture and factories in the near future. 28
Scale 2 Scale 3
SCALE II
SCALE III
The problems posed in that scale are problems which directly relates with its legislative status of the Wadden Sea. The major problems posed by these authorities are:
1. Most Dynamic Island Island Schiermonnikoog is the most dynamic island among all other West Frisian Islands. This implies that the Dutch Government must allocate a higher budget for the sand nourishment than they spend for other islands. Especially with the effect of sea level rise, this situation may create a conflict between immobilisation of the island and the sand budget.
THE WADDEN SEA
ISLAND SCHIERMONNIKOOG
1. Loss of Habitat The Wadden Sea is a unique habitat for mammals and birds. The loss of its habitat is threatening the species living around this heavenly habitat. Sea level rise and gas extraction around the Wadden Sea is a serious threat to its unique habitat.
2. Highly Affected by Tidal Changes Since the island is a part of an ebb-tidal delta, the sea level is changing twice a day. From Den Helder to Bremen, the water level difference goes from 1,4m up to 4,4m. Thus, the daily tide difference in the island is between 2 - 2,5 meters. However, during the storm surges the maximum recorded setup in the water is about 3,4 - 4 meters. These numbers are expected to get higher with the effect of climate change.
2. Need for a Sustainable Tourism The area is also a favourite destination for tourists, especially for the bird watchers since it is on the flyway of numerous bird species. Some also use the islands and sandbanks to leave their eggs and to breed. Thus, tourism is an important source of income but these activities should meet sustainability criteria.

Archetypal Struggle Against Water
| Demise of Jordsand: Creation, Continual Shifting, Changing and Ultimate Disappearance | The Last One Hundred Seventy-five Years of the Island Schiermonnikoog
Demise of Jordsand: Creation, Continual Shifting, Changing and Ultimate Disappearance
The observation hut on Jordsand on fire Photo: Svend Tougaard. The island Jordstand is one of the most extreme islands of these disappeared ones. The island, which used to be an island on the Danish border of the Wadden Sea was destroyed in a series of storm tides. However, in 1971, it was as big as the island Schiermonnikoog. Since it was not protected by dikes and wasn’t nourished by sand, it has disappeared in the currents of the North Sea. Today it is just a shallow sandbank and not more than a google landmark on the map. Studying the case of Jordsand carried my morphological research into reconsidering the island Schiermonnikoog which is also threatened by disappearance because of tidal changes and its dynamic morphology. By taking the Jordstand case into account, I aimed to project a future scenario by asking the question “What if the island Schiermonnikoog slowly disappears in the currents of the North Sea.” Jordsand Today Photo: Google 40

The Last One Hundred Seventy-five Years of the Island Schiermonnikoog
Migration Pattern of the Island & Lessons taken from the Badhotel Case Barrier islands consist of five large-scale morpho ecological units. The island Schiermonnikoog contains each of these units within itself. And, each of these units behave differenty within the complex sedimentary system. While the island head (1) is corroding over the years, with the effect of sand nourishment supplied by the Dutch authorities, the shape of the tail remained almost same during the 175 years. The Badhotel case demostrates the effects of the corrosions on the island head (1) without implying sand nourishments. On the other hand, the same authorities did not interfere to natural accumulation of the sand on the island tail (4), Beach and shoreface (5). Thus, the island tail (4) and the beach and the shoreface (5) got longer and longer over the years.
Badhotel Case Badhoter 1924, From the archieve of Eddie Bakker In 1887, the owner of the island I.E.Banck has built a large bathhouse which has its own light house and pump installation which provides water to the hotel. In 1916 the sands underneath of the hotel slowly began eroding and eventually in 1924 the hotel was damaged by the sea water. At that time, there were 80 guests in the hotel which proved that teh resort was quite populer among Dutch community. And then in the same year that it was damaged, it was completely demolished.
The sand nourishments prevents the mobilisation of the island to the North-east. As a result, the island looks like it stands on its place but getting longer on the North-east border.
Prototype Island The prototype West and East Frisian barrier island is characterized by the presence of five large-scale morpho-ecological units: (1) island head; (2) dune arc; (3) washover complex; (4) island tail; (5) Beach and shoreface Source: Lรถffler et al., 2011 42

MICRO TIDAL
TIDAL RANGE 0-2 METERS Micro-tidal environments are those in which the tidal range is 0-2 m. These Island tend to be long and thin with few inlet channels. In micro- tidal environments that tidal surge is not large enough to top the island in many places. Without continual overtopping by tidal surges there is not the opportunity for many tidal inlets to form. Barrier islands in micro-tidal environments are considered to be wave dominated barrier islands.

MACRO TIDAL
TIDAL RANGE >4 METERS Macro-tidal environments are in areas where the tidal range is > 4m. Macro-tidal areas are considered to be barrier island free. Barrier islands exist in macro-tidal environments only very rarely when fluvial input is the dominant factor.
0
4
8 km
MESO TIDAL
TIDAL RANGE 2-4 METERS Meso-tidal barrier islands form in area in which the tidal range is from 2-4 m. The island systems which form in these environments tend to be shorter in length by slightly wider. The reason for the shorter length is continual overtopping by the tidal surge. This allows the formation of many inlet channels and hence the formation of many distinct islands. Meso-tidal barrier islands are considered to be tidally dominated barrier islands.

MODIFICATION OF DUNES (1) Westerduinen (2) Oosterduinen (3) Kobbeduinen (4) Kooiduinen The size and morphology of coastal dunes is dependent on the complex interaction between controlling winds, sediment supply, and the geomorphology of the nearshore and beach environment. At the most basic level, dunes can be divided into those that form from the direct
supply of sediment from the beach face (primary dunes), and those N that form from the subsequent modification of NNE primary dunes (secNNW ondary dunes).

Island as a Source of Water
Water Production Facility in the Island Schiermonnikoog April, 2018 74
The island is a natural source of water. Nowadays, the island contains two surface water extraction facilities. One of them is located on the South-east of the Westerduinen. This production facility contains considerable amount of water wells around the duins in order to collect the fresh water which is naturally collected under the dunes.

Ravenous Water Wolf
86
The long-standing battle between the Dutch and against water became the central tenet of my research. The heraldic motto of Zeeland, ‘Luctor et Emergo’ means ‘I struggle and Emerge’ in Latin, and is the name given to the project. During my research, I scanned numerous maps from archives and books to investigate this battle and how it is represented. The representative image on the cover is a symbolic depiction of this battle as an animalization of the Netherlands, an orange lion, battling with a grey sea wolf. This depiction is originally comes from a map of Harlemmermeer planned by Jacob Bartelsz in which you recognize the lion and the wolf above the poem of Joost van den Vondel who calls it the ‘Ravenous Water Wolf ’.

JA N U S Janus Like Gods Since each of these four themes perceived as a thematic backbone of the Dutch waterscapes, they conceived as Janus like gods in the myth of “making new land”. Because Janus is the god of beginnings, gates, transitions, time, duality, doorways, passages, and endings. He is usually depicted as having two faces, since he looks to the future and to the past.

Conflict
De doorbraak van de Sint Anthonisdijk bij Amsterdam Willem Schellinks, 1651, Amsterdam Museum
90
The conflict means the conflict between the wet and dry. The disastrous floods, breaking dikes, sunken ships are representing the conflict between the solid and liquid states. Intervening the nature with heroic structures are also part of this conflict. For example, the Afsluitdijk which turned the Zuiderzee into a lake, changed the dynamics of water and split the sweet and salt.
91
Concord
Siege of Leiden Jan Maire, Henrick Haestens, Jan Jansz Orlers. 1614
92
The amphibious life of the Dutch means concord. Concord comes to life where the water management behave the enemy – the water - as an ally. When the Dutch give a room to the enemy by the canals, but also combining it with dams and locks, they somehow proved that they concord with the water. The Siege of Leiden occurred during the Eighty Years’ War is a beatiful example for the theme of concord.
93
Profit
Departure of a Number of East Indiamen from the Marsdiep Hendrick Cornelisz Vroom, c.1600-1630, Rijksmuseum
94
Profit means, profiting by this amphibious life. It sometimes comes into life with ships which were like some small replicas of little Dutch towns. By this way, with a strong navy and seafaring they prosper by harvesting the seas. But in the mainland, they also prosper by the utilitarian landscape that they have designed. Windmills are the most beautiful examples of how to keep the land dry, by pumping the water out but also profit from it by using it for production and habitation.
95
Pleasure
Winter Landscape with Skaters Hendrick Avercamp, 1608, Rijksmuseum
96
Pleasure means to cherish the dynamics of this landscape and the states of water. Pleasure is about the lifestyle. For instance, taking your boat at the weekend and sailing with your boat or skating on a frozen lake is pleasure of this amphibious life.

Territory as a Project
“Territory As a Project� is a one-day symposioum and exhibion held at TU Delft, Faculty of Architecture and the Built Environment. The students of Delta Interventions Graduation Studio 2017-2018 were asked to join the exhibiton with a representative image of their proj-
ects and a representative physical model. The exhibiton convened by Dr. Arch. Taneha Kuzniecow Bacchin and Dr. Arch. Hamed Khosravi and curated by Geert van der Meulen, Elise van Herwaarden and Gerben van den Oever.

The Exibition poster was an opportunity to answer the research question “What would be the new myth of water defence which response and works with the accelerated dynamics of the Wadden Sea in the future?” with a drawing etude. It is also an attempt to answer the question “How these four themes: conflict, concord, profit and pleasure can be implemented in future designs and what would be the spatial consequences of interpretation of these four themes?”

Scale and Typology Etudes & The Early Proposals
| Fortifications: Walls as Rooms | Cisterns: Learning from Archetypes | Infrastructure of Dead Souls | Compositions
Fotifications: Walls as Rooms
After the implementation of the four themes, some typology research about the forts and fortifications around Europe became a necessity. Because the theme conflict was projecting an idea about to protect the North-west of the island with a fort and conflict with the dynamic nature of the Wadden Sea. Like fortifications, British castles as well were worth to investigate because of their similar typology to forts. Because both forts and castles were composed of “wall as rooms”. Louis Kahn was known for his interest in Scottish castles. With an ode to Kahn’s work and interest, Fort Boyard and Hedingham castle were studied to understand their organisational principles in plan and section. Fort Boyard Photo Source: Anthony Penel Fort Boyard was built on a sandbank which is also called “Boyard” on the West coast of France. The construction was begun in 1801 and the fort was finally completed in 1857. But, the original project was proposed as early as the 17th century.

Cisterns: Learning from Archetypes
After the implementation of the four themes, it was decided to learn from a major archetype, cistern. Because the theme profit was projecting the idea of protecting the the North-west of the island with its natural sources of water. Yet, the island has the source and extraction facilities for it but preserving it in a type of construction had never even been thought of before. Three infrastructure selected from three different cultural backgrounds. They also date back to different times in the history. But one common typological characteristics of them are the same: a forest of columns. Basilica Cistern Photo Source: Unknown The Basilica Cistern is a Byzantinium cistern that lies beneath the city of Istanbul. This cathedral-size cistern is an underground chamber capable of holding 80,000 cubic metres of water. The ceiling is supported by a forest of 336 marble columns, each 9 metres high, arranged in 12 rows of 28 columns each spaced 5 metres apart.

Infrastructure of Dead Souls
The theme concord was projecting an idea about to mark the landscape like the navigation marks on the sea. It means behaving the dynamic seascape of the Wadden Sea as if it is like the land. So the fortification of the island can concord the landscape and remain still, while the malleable habitat around it constantly changes. This gives a second function to the fort, the infrastructre of dead souls, rather than being an infrastructure of water.

The island has no concrete industry to build solid and durable constructions with concrete and the logistics Chapter 2 - The Hydraulic Machine

purified, it is sent to the cistern with the aqueduct. The Cistern is placed at the end of the Hyrdraulic Machine which remains on the south-west of the fort. The Cistern has a massive body and an underground ‏space where the final processed water is collected below the ground surface. As the island changes within the forces of the Wadden Sea, the dunes get lower and the water lenses below them get smaller. At that moment, the fort starts to pump the salt water inside and begins the desalination process.

of the sea. The machine starts carrying sand from the East to the West to keep the ground safe and rigid. In other words, from where the sediments are deposited by sedimentary systems to where the sediments are eroded. Some more people are charged with filling the river barges with sand, crossing the canal and leaving it in the places exactly where the erosion is hazardous.

One day, during the dredging processes of the sand from the Eastern peninsula they discovered the archaeological remains of an old monastery which was built and disappeared hundreds of years ago. This creates huge enthusiasm among the public and the archaeologists. Initially, only a group of archaeologists arrive at the fort to preserve and reconstruct the remains of the old monastery. They inhabit the abandoned parts of the hydraulic machine as a workspace and a shelter. After the reconstruction of the monastery, they find some other remains around the territory of the fort. Other artefacts were also found in the remains of the buildings which were created on parts of the island that had become submerged. Then the archaeologists completely colonize the submerged territory, to find and reconstruct the remains of lost artefacts from the disappeared island. Eventually, the fort becomes an infrastructure for the dead souls of the island Schiermonnikoog.
