Hydro - Geomorphic and Socio - Economic Aspects of River Bank Erosion: Middle Diana River Basin, Jalpaiguri, West Bengal

Amrita Kar

Abstract: Riverbank erosion is one of the most unpredictable and critical type of fluvial hazard that takes tolls less in lives but more in livelihood such as agricultural land and homesteads along with other livelihood options that are evacuated. River Diana, the main right bank tributary of the Jaldhaka, originates in Bhutan and flows south - westward into Jalpaiguri. The present study concentrates on middle Diana basin where intense problems of bank erosion and spilling exist. Channel migration and severe bank failures have taken place almost every year that have severe impact on surrounding areas. Because of the dynamic nature of the braided river and the failure of structural measures, the sufferings of the people continue.
