The Hedwige- and Prosperpolders are situated on the border of Belgium and the Netherlands near Antwerp, as presented in Figure 1. A polder is a low-lying tract of land that forms an artificial hydrological entity, enclosed by embankments known as dykes. It is decided that the two polders will be turned into an area with intertidal nature (managed realignment). Together with the ‘Drowned Land of Saeftinghe’ they will be part of the largest intertidal nature area in Western Europe. The reconstruction means that the current dyke along the river Scheldt will become obsolete and partially removed. This presents a unique opportunity to perform full-scale tests on this dyke, which has been in service for several decades. BZ Engineers & Managers commissioned by The Dutch Foundation for Applied Water Research () and the Belgian Flanders Hydraulics Research (FHR, Department of Mobility and Public Works) have joined forces to organize these experiments. Together with several other partners, including knowledge institutes, universities and flood managers, the test and experiments will improve understanding of the impact of floods incidents and of climate change. Field experiments on the Scheldt dykes form the core of the collaboration.
