“…The main concern of dam failure and dam release analysis in Egypt studies is concerned with old Aswan dam, High Aswan Dam & Grand Ethiopian Renaissance Dam (Helwa et al, 2020;Sadek, 2010;Soliman et al, 2014) . (Mhmood et al, 2022) used HEC-RAS to predict the flood propagation wave downstream of Haditha Dam in Iraq.…”

Although it is a low probability, the collapse of flash flood protection dams in arid areas cause dramatic disasters. Such event is extremely unpredictable, so it is necessary to estimate probable flood characteristics over inhabited areas. Analyses of dam break consider the parameter of dam breach to quantify and route the outflow hydrograph due to dam break. Several dam failure simulation models are used to predict dam failure shape and timing, HECRAS being one of the best known. Three cascade flash flood mitigation dams in upper Egypt were breached in 2014 but the details of the event weren't recorded. In this paper, we investigate the application of HEC-RAS 2D in dam break analysis as an early warning system, emergency action plans, and flood mapping implementation tool. That is a powerful tool to understand the complexity of these events and its consequences. HEC-RAS 2D is used to build a hydrodynamic model for a dam breaching case, its reservoir and the downstream flooding zone. The results include flood extent, dam's outflow hydrograph, flow depth and velocity over the inundated delta, and arrival time. After completing this work, further studies for other failing scenarios are required to achieve complete understanding of that disaster.

“…The main objective of this study is to depict the flood hazards due to GERD break on the area bounded by GERD and the AHD. Soliman et al (2019) divided the area between GERD and AHD to six separated reaches. The modelling of GERD break shows that, the peak outflow is 2000000 m3/s and occurred within 5 hr from the beginning of break.…”

Flood due to Dam break can cause a huge loss to human life and property on the downstream area. This loss to human life and property depended on extent of inundation area, size of population at risk, the propagation of flood waves and the amount of warning time available. This paper presents flood hazards on Sudan and Egypt due to Grand Ethiopian Renaissance Dam (GERD) break. The GERD is located at 20 km upstream of the Ethiopian-Sudaness border on Blue Nile River. GERD break may be occurred due to many different reasons such as structural instability, overtopping and seepage. Earthquakes, landslide and sabotage can be leads to insidious GERD break. Outflow hydrographs due to GERD break were obtained by HEC-RAS model. The Blue Nile and the Nile River downstream of GERD until the AHD is simulated using SOBEK 1D-2D model. The related data were collected to simulate and analyze GERD break hazard. A risk assessment of the GERD break is obtained. The flood wave propagation is found in terms of inundations maps. The flood water levels and arrival time downstream GERD to AHD is achieved. The results of this investigation could be used to help decision makers to prepare an emergency plan and warning systems to rescue the affected downstream area and to put an evacuate plan.
