The Hungry Tide; escape from the discipline of geometry

This exhibtion is the first presentation of our research for the project 'Balanceren tussen zoet en zout' of the Bewaerschole in Burgh Haamstede. We looked closely at the substances salt and sediment and their role in the landscape of Schouwen-Duiveland. The coastline is not a clear line, nor a clear division between land and the sea. There are many forms of water that don’t fit into the discipline of geometry. We should be able to place water in its own sphere, subject to states and cycles of hydrology, making the coastline not a geographic transition from land to sea but a dynamic chasm where twice a day water rushes in and out with the tide. With the prospects of a changing climate and sea level rise, controlling water increasingly becomes a precarious task.

The intertidal zone around the island is changing because of the delta works. Where once water flowed freely around the island there are now 4 distinct bodies of water: the Noordzee, Oosterschelde, Grevelingenmeer and the Volkerak. From these 4 locations we collected water samples.

The phases of the moon affect the height of the tides. This is no longer felt because of the separation of the dykes between the land and the sea. Where normally the incoming tide meets the outflowing river there is now a dam. This disruption stops the exchange of fresh and salt water.

We’ve made a artificial gradation from water fully saturated with salt to fresh water, with seawater coming half way down the scale. As much as we tried to control the salinity each individual plate reacted differently. We tried to recreate a natural gradient by artificial means calibrating the relationship between fresh and salt, thereby creating our own standard, and making a visual instrument to relate the gathered samples to the scale.
