The Aswan High Dam Completion and inauguration

The Aswan High Dam was constructed in 1970 and operational in 1976 (Goharian et al., 2022). It is in southern Egypt and forms one of the largest artificial lakes in the world, 500 km of length, in the Egyptian (350 km) and Sudanese lands (150 km) (Genidi et al., 2023; Goharian et al., 2022; Sweed, 2023). This reservoir is one of the largest storages controlling the outflow into the Egyptian Nile Valley (Goharian et al., 2022; Ilgen et al., 2024). The reservoir is in a very hot and dry climate which means the evaporation rates can be specifically high in riparian areas and khors representing 79% of the total lake area (Ilgen et al., 2024). The dam plays a pivotal role in the water resources and economic sectors of Egypt and part of the Sudanese territories. It, additionally, protects Egypt against long-term floods and droughts (Goharian et al., 2022; Ilgen et al., 2024). Furthermore, it serves for hydropower generation throughout the year, generating an annual electricity up to 10 000 GWh (Ilgen et al., 2024). The region has faced a significant seismic activity, including the 1981 earthquake (5.6 ML) and a 2010 event (4.6 ML) near the spillway fault, raising concerns about the stability of the High Dam, because of the proximity to essential infrastructure (Genidi et al., 2023; Hamed et al., 2024; Mohamed et al., 2022). Additionally, two crack zones beneath the spillway fault allow water seepage, leading to expansion and potential impacts on the dam’s structural integrity (Mohamed et al., 2022).
