Morphodynamic assessment of side channels

Side channels are often constructed to increase the conveyance capacity of the river and to increase its ecological value. As part of his PhD, Pepijn van Denderen (MFS group) estimated the development of several side channel systems and the corresponding timescales. Together with co-workers, he computed the morphodynamic development by using a simple one-dimensional bifurcation model and he compared the results with aerial images of four side channel systems in Europe and North America. The main result is a set of stability diagrams with the main side channel characteristics that can be used to assess the development of side channel systems and the associated timescale, which will aid in the future design and maintenance of side channel systems.
