Since 1500 the marine clay area in the province of Noord-Brabant has been transformed from a delta with salt marshes and mud flats into a very well-drained polder landscape. The present dynamics of the water system have been achieved over the centuries by channelling sea-arms and dyking creeks. However, climate change and government policy measures could lead in the near future to flooding and a shortage of clean water in the area. Proceeding from the topography and the characteristics and existing features of the landscape, I have tapped and exploited these issues in my proposal as opportunities to be taken. The water surpluses in winter can be stored to alleviate the water shortages in summer. This way, agricultural land can be supplied with water along sustainable lines and the characteristic emptiness of the marine clay area retained.

The design constructs large storage tanks in the marine clay polders, guided by existing dykes and old creek beds. In winter these are filled with river and rainwater. During the summer, the water in the tanks is used for agricultural purposes; plant life will spontaneously emerge as the water level drops. The tanks change character with the seasons and colour the marine clay landscape. They additionally have great recreational and ecological value and infuse new life in existing villages and forts. The northern tanks can accept water from Hollandsch Diep in the event of serious flooding.

The Mark, Dintel and Vliet rivers gain a more dynamic and more visually definitive character. Other storage tanks are laid out in the outer marshes adjoining the polder landscape, with a sensitively designed avenue of trees marking the border between polder and storage tanks. The outer marshes in the south are laid out as floodplains.

The 'Seam', the transition from low-lying marine clay polders to more elevated sand deposits, is a source of drinking water extraction, a process that can restore the nature in this seepage area. It also doubles as a possible flood storage zone serving the Mark and the Vliet.
