ABSTRACT
Sediment is one of the largest carriers of contaminants and is one of the most important issues in environmental hydraulics. It is, therefore, not surprising that sediment transport has received considerable attention for over a century. Watershed management, river training works, reservoir sedimentation, design of a variety of hydraulic works, and pollutant transport require calculation of sediment discharge or yield. Sediment discharge is computed by employing different combinations of different methods of computing channel cross-sectional velocity and suspended sediment concentration distribution. The velocity may be computed empirically or using the entropy theory, and the same is true of the sediment concentration. The objective of this chapter is to discuss the computation of suspended sediment discharge using different combinations of velocity and sediment concentration distributions.
