Abstract:Sedimentation is of vital concern in the conservation, development and utilization of our soil and water resources. The suspended sediment in estuarine waters is hazardous to navigation in estuaries, which have important ports and harbours. A breadth-averaged numerical model to study circulation and sediment transport is presented in this paper. The model is applied to Hooghly estuary, along the east coast of India. The model is fully non-linear and uses a semi-explicit finite difference scheme to solve mass, momentum and advection diffusion equation for suspended sediments in a vertical plane. The erosion and deposition have been computed by empirically developed source and sink terms in the suspended sediment equation.
