Sediment transport in irrigation canals makes water management very complicated. This study focuses on water management in Gezira Scheme, Sudan. This scheme is irrigated from the Blue Nile River, which is characterized by a high sediment concentration. The aim of the study was to reduce the impact of fine sediment deposition in irrigation canals by improving the operation and maintenance procedures. A numerical model has been developed to simulate the cohesive sediment transport in irrigation canals. This model is a useful tool for the operators and decision makers to assess different options of operation in terms of sediment transport. This study found that sediment deposition in the canals can be minimized if the operation based on crop water requirement is adjusted at a certain period during the flood season.
