NWRC has held a late technical session entitled “TS26 Dam Break Risk Assessment†on Wednesday 23 October 2019 during the Cairo Water Week at the Volga River Hall - Al-Manara International Conference Center. The session was chaired by: Prof. Mostafa Gawish (Emeritus Professor at NWRC), and co-chaired by: Prof. Sami Abdel Fatah (Director of Hydraulics Research Institute). The session discussed Dam failure, either earth or concrete dams, that occurs due to natural disasters or man fault. Consequently, the failure causes losses of lives and, economic drawdown due to uncontrolled flooding. Research on dam failure/break is very crucial for predicting the negative impacts and accordingly for the necessary measures of mitigating such impacts. NWRC will present the large small scale experiments that conducted, using the large facilities that are available in the NWRC, for studying the breach of earth dams due to overtopping or piping. Research and studies were presented on concrete dams break and its impact downstream using numerical modeling techniques and risk management analysis. The presentations were: “Embankment Failure and Leve’e Breach (Joint Research Project)’, by Dr. Mohamed Abdel Latif, HRI; Influence of Upper Nile Dam projects failure on the HADAâ€, by Dr. Mohamed Roushdi, NWRC Secretary General; and finally “State of Art on Dam Surveillanceâ€, by Prof. Ashraf Al-Ashaal, Emeritus Professor at CRI.
