Impact of sediment dynamics on flood risk in the Karnali River basin

In this blog post, Dr. Dilip Gautam (Senior DRR Consultant – PAC) considers sediment and flooding dynamics within the Karnali basin. In most of the current flood risk management practices, the role of sediment dynamics is not dealt with sufficiently. Sedimentation of river channel and floodplain has serious impacts on aggravating flood risks in alluvial river system. This blog focuses on the relationship of sediment dynamics and flood risks in Karnali River basin of Nepal. The idea is to integrate sediment dynamics in flood forecast modelling and follow comprehensive approach on flood risk management with due consideration on control of erosion and sedimentation.
