Because of climate change and rising sea levels, it is crucial to keep investing in the Sigma Plan. The Sigma Plan is about higher and wider levees, a chain of flood areas along tidal rivers (FCA and FCA-CRT) and local depoldering. This is how we protect the entire region of Flanders from flooding from those tidal rivers at storm tides. A storm tide happens when a spring tide in the Sea Scheldt Basin coincides with a (north)westerly storm on the North Sea. We are also restoring the natural bends or meanders of the rivers in certain places. That is because they are natural buffers during periods of high precipitation. In summer, they also stop areas from getting too dry, just like barriers on the riverbed.
