Replication data: A characterization of side channels

Side channels are commonly constructed to reduce the flood risk or to increase the ecological value of a river. Such artificial side channels generally aggrade. We categorization the development of side channels based on the sediment that is deposited in these channels. Based on this categorization, we determine the main mechanisms that affect their development and we propose an initial framework on how to predict the long-term development of side channels. The results can be used to design, operate and maintain side channel systems.
