Abstract: Present paper deals with development of a new mathematical model to simulate non-equilibrium transport of suspended sediment in open channels, with special emphasis on sediment overloading. Equilibrium transport of bed sediment is also included. Sources of the suspended sediment are from the catchment (such as construction sites, mining areas etc.). This sediment is brought into rivers and canals by flowing rainwater. Its overloading can result in large changes in bed and water levels of the rivers and also in heavy silting of the canal beds. A new mathematical model to simulate this effect is derived based on the control volume approach. The model is tested using data available in literature and results are found satisfactory. The developed model is then applied to a hypothetical flood and sediment routing problem in a river and analyses of the results are given.
