A categorization of side channel development as a function of the type of sediment that is deposited in the side channel.

Innovative components

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 categorize 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 longā€term development of side channels. The results can be used to design, operate, and maintain side channel systems.

Findings and implications to practice

We present a categorization for side channel systems such that the main mechanisms for its development are easily identified. In addition, we propose an initial framework to easily estimate the side channel development that will help to optimize the design, operation, and maintenance of side channels.

Explaining artificial side channel dynamics using data analysis and model calculations

We studied in detail the development of a side channel in the river Waal. A more frequently flowing side channel results in lower aggradation or sedimentation.

Morphodynamic assessment of side channel systems using a simple one-dimensional bifurcation model and a comparison with aerial images

To aid the future design and maintenance, a set of diagrams allow to estimate both the equilibrium state and the time that takes for the bed load of the main channel to aggrade or deposit in the side channel.
