On the dynamics of side channels as rehabilitation measure: linking theory and practice
Side channels are a popular method to restore the ecological value of the river and to lower the water level during floods. However, due to erosion and sedimentation processes in the side channel, regular maintenance is required. An optimal design of a side channel minimizes the cost of the maintenance, but requires a better understanding of the processes in and around the side channel. These processes include the sediment distribution at the bifurcation, the effect of graded sediment on the sediment distribution and the erosion/sedimentation processes in the main channel and side channel. My PhD research is part of a larger research program Rivercare.
