Sills increase the groundwater level
To protect the region from flooding and, at the same time, to allow wetlands to develop, the winter riverbed will be restored and the groundwater level will be raised using river sills. On the banks, wide reed beds will give way to wet grasslands. In this biotope, a wide variety of rare species, such as the great bittern, the spotted crake, the chabot bullhead and the beaver, feel right at home.
At certain places on the bottom of the Grote Nete, we will install sills to elevate the level of the groundwater. This way, wet river nature can continue to grow even in dry periods. Don't these sills increase the risk of flooding? No, they don't. They only affect the river when the water level is low. If the water is high, its level will rise above the sills anyway.
