A Review of Numerical Models for Sediment Dynamics

Sediment dynamics plays a very important part in erosion, floods and morphological changes in the river. The sediment dynamics can be analysed by studying the basin and river parameters. There are different techniques to investigate the sediment dynamics. Numerical modelling of rivers for studying sediment dynamics is rapidly being utilized to investigate river pattern changes, and the information acquired from these studies is used by environmental managers and decision makers. There are a lot of numerical models present for these studies. But all of these models vary in some way or the other. They may vary in their intricacy, inputs and outputs, advantages and disadvantages and so on. In light of these issues, this research examines various numerical models and their approaches with regard to sediment dynamics. Upgradation of these numerical models from the time it was first presented has been discussed in the paper. A summary of some specific numerical models is given. The purpose of this paper is to understand different numerical models and the usage of these models in a given research, so that the sediment dynamics of a river can be studied.
