Continuous simulation of suspended sediment through a stream section
This paper presents the development of a one–dimensional stream water quality model for the continuous simulation of suspended sediment transport and deposition processes along a particular stream section. The model integrates stream hydraulics and suspended sediment transport and deposition processes. The stream hydraulic model was developed using the Muskingum–Cunge method of channel routing. The well–known suspended sediment processes have been modified and integrated with the developed hydraulic model. The developed model was applied and simulated for the Saltwater Creek, Gold Coast, Australia. Sensitivity analysis of the model showed that all the particles' characteristics within the incoming stream flows are important for the better prediction of suspended sediment loads.
