Short summary
Mountain rivers can mobilize important amounts of sediment that endanger downstream dwellers and infrastructure during floods. Sediment traps are built immediately upstream of urban areas to retain hazardous sediment. However, many sediment traps retain too much sediment, which is then missing in downstream river sections, leading to a poor eco-morphological state. This study proposes an experimental research-based solution to improve sediment traps using a guiding channel.
