About the project
Side channels are a popular measure to restore the ecological value of the river and to lower the water level during high discharge. Regular maintenance of the side channel and the main channel is required due to erosion and sedimentation processes. This erosion and sedimentation is caused by the spatial change in river geometry resulting from a side channel, and the development of vegetation in the side channel. An optimal design of a side channel minimizes maintenance costs, but requires a better understanding of the processes in and around the side channel. The aim of this project is to develop a procedure for the design of a side channel that minimizes maintenance. The project focusses on unequal bifurcations, which are bifurcations of side channels with a small discharge relative to the main channel discharge, and the sorting effects at these bifurcations.
