A2-d model simulating the sediment transport in rivers

A 2-D mathematical model (SED-2) was developed to simulate thesediment transport in alluvial shallow-wide streams in order to solve practicalproblems in the River Nile. The Finite Difference technique was used to solvethe convection-diffusion equation of the suspended sediment in open channels.A 2-D hydrodynamic model (HYD-2) was used to describe the flow fieldsolving the Reynolds form of the Navier-Stokes momentum equations in twodimensions in addition to the continuity equation. The developed 2-Dmathematical model (SED-2) was verified using measured field data. The fielddata were collected from one of the irrigation network main canals in Egyptcalled Elnubaria. Good agreement was observed between the model results andthe field measurements. The model has been applied for solving naturalsediment problems at Elbogdady reach, south Luxor staff gauge, 712.80 kmD/S of Rod a staff gauge on the Nile River. The main purpose of the applicationwas to investigate the navigation problems in the considered river reach and tosuggest the best location for the required quay or platform.1
