Sediment Dynamics in a Large Alluvial River: Characterization of Materials and Processes and Management Challenges

Abstract

Sediments of a large alluvial river often hold the key to its geoenvironmental behavior. Several physical and chemical behaviours of high sediment carrying river including water quality, bank line shifting, sediment budget and bank erosion are influenced by sediments. The current study carries out a partial evaluation on some of the key factors. Considering severity of bank erosion problem in the last few years, six locations on the river Brahmaputra were considered for this study. Role of individual bank material properties in bank erosion were studied with binary logistic regression using SPSS.
