The present paper assesses the risk of the Aswan High Dam breaching, numerically. Literature, in the field of dam breaching, was reviewed. The Aswan High Dam was visited. Site data, so as measurements data, were collected and analyzed. A suitable numerical model was chosen and was selected to be implemented. Scenarios were designed. The expected impacts of the Aswan High Dam failure that might result from overtopping or piping was simulated and the obtained results were analyzed. Outflow hydrographs due to the failure mode were obtained and analyzed. A risk assessment to the dam breaching was achieved. The results of this investigation could be further applied and could assist decision makers to set a plan to confront the risks of the Aswan High Dam failure.
