Mechanisms and Countermeasures on Sediment and Wood Damage in Sediment Retarding Basins

Improvements in sediment retarding basin design are required to mitigate flood damage caused by bed load and wood debris outflow in lower river reaches. We used a scaled sediment retarding basin model to optimize our basin design, with the goal of improving sediment and wood debris transport and cap...
