Abstract

The causes and mechanisms of sedimentation in the lower reach of the Rupnarayan River are explained in connection to stream energy, environment of sediment deposition and understanding of the sediment sources from mineral composition. Seasonal fluctuation of available and critical shear stress, cohesiveness of sediments, sheltering of sediment particles, effects of biological activity and organic content are the main factors to control the mechanisms of sedimentation. Environment of deposition is examined and understood by Linear Discriminate Analysis (LDA) technique and bi-variate plotting of grain size parameters. Hydrodynamic processes working during the deposition of sediments have been identified by C-M plotting. X -ray diffraction (XRD) technique is used to understand the sources of sediments through identification of mineral composition.
