SEDIMENT TRANSPORT SIMULATION IN IRRIGATION CANALS USING A NUMERICAL MODEL FSEDT
and maintenance scenarios the model was used as a tool. The predictor corrector method is used to solve the gradually varied flow equation for the prediction of water surface profile. The solution of the one dimensional advection-diffusion equation is bases in the prediction of sediment concentration. The change in bed level was computed based on the sediment mass balance equation that was solved numerically by using the finite difference method. The model has been applied in the Gezira Scheme. The model was calibrated and validated basis on the field data. The predicted bed profiles depict good agreement with the measured ones. The model is capable to predict the bed profile for any period of simulation.
