River networks are considered as conduits of variable conveyance flow from an engineering perspective. Alluvial channel networks alter their planform, and extent over time. The main objective of the research is to estimate the maximum conveyance capacity of the Rosetta branch of the Nile River in Egypt. A two-dimensional numerical model was used to evaluate the morphological and hydrological changes that occurred during a period of 17 years from the year 2003 to 2020 in the branch using different flow scenarios. The results show a prevailing deposition trend along the branch leading to a reduction in the maximum conveyance capacity. Three rehabilitation scenarios were proposed to increase the maximum conveyance capacity. Each scenario was evaluated by assessing its impact on the conveyance capacity, surface water elevation, and inundated land area. The proposed rehabilitation scenarios increased the maximum conveyance capacity and reduced inundated land area, but lowered the surface water elevation.
