The smallest particle as a solution for the turbid Western Scheldt
Liquid Land presents a design proposal to combat the turbid water of the Western Scheldt using natural forces that can decontaminate it. The Western Scheldt is a polluted estuary, an open inlet that is simultaneously a river mouth. This project calls for another way of addressing the turbid water and silt by no longer regarding the silt as waste. This can enrich the nature on site without affecting the estuary's contributions to the economy.
The Western Scheldt is one of the last open inlets left in the Netherlands. One of the world's busiest waterways, it has dykes on both sides so that we can live safely in the low-lying polders while ships make their way through to the docks. Although this is a nature conservation area, functionality is uppermost, its recreational values are barely present and the natural dynamics are under pressure.
Turbid water limits the growth of algae, the bedrock of the food chain, and this has disastrous ecological consequences. During the past fifty years, the increased scale of shipping and dredging has made the Western Scheldt deeper on average and consequently more turbid.
The key to redressing this turbid state is the smallest particle, in the form of negatively charged silt particles. These attract positively charged toxic matter such as dioxins and heavy metals. And the Scheldt basin has a rich history of toxicity. Industrialization, urbanization, pollution and the long delay in getting water purification in place upstream have left large deposits of contaminated silt in the Western Scheldt.
Liquid Land introduces concrete measures that are to solve this problem. These include physically moving with the estuary, less water in the system and catching and processing contaminated silt for use as building blocks, thereby stimulating siltation, dune formation and ecological richness.
The silt can be made into large building blocks. In the project, the place near Antwerp where the toxic silt is to be collected changes with the construction of a double dyke in a water purification landscape, and a toxic mine. The dyke also serves as the quay from where the blocks are shipped to their destination elsewhere in the Western Scheldt where they can foster new dynamics, siltation, dunes and an accessible landscape. This has been worked up in detail at a site near Borssele. This project shows that the silt in the Western Scheldt can be used to solidify liquid land.
