Restoration of the winter river
In the Tussen Hellebrug en Herenbossen and the Zammelsbroek areas, we are restoring the winter riverbeds. A winter riverbed is the section of a river that remains submerged under water throughout the entire winter. There is more precipitation in the winter than in the summer, and this causes the river to overflow its narrower summer bed.
The restored winter riverbed provides more space for flooding. The winter bed is the section of the river that is submerged under water during the winter; this bed is created by lowering certain levees. This way the river can flood safely. The natural contours or natural levees protect the hinterland. The winter riverbed utilises the natural contours, which gradually rise along the banks of the Grote Nete toward the hinterland, to safely contain the water. In some places, these contours are not enough. Therefore, the houses and roads in low-lying areas are protected with a local levee. Sometimes it is enough to elevate an existing road or path. The water remains in the winter bed until it flows naturally back to the river, penetrates into the ground or evaporates.
