Sediment Management of The Himalayan Rivers:A Challenge for River Managers

A river transfers both water and sediments through its journey from its source to sink, and the form and processes in a river channel are strongly influenced by the balance of these two fluxes. In case of the Himalayan rivers, sediment delivery from the tectonically active hinterland is exceptionally high compared to rivers draining from the peninsular India. Monsoonal rainfall in the Himalayan hinterland further helps to bring these sediments down into the alluvial reaches of the rivers where lower slopes and wider channels encourage natural deposition of sediments.
