摘要

Climate change significantly impacts dam safety by increasing the frequency and intensity of extreme weather events, leading to greater hydrological uncertainties. Past failures, such as the Derna disaster, underscore the vulnerabilities of embankment dams, particularly to overtopping and subsequent erosion. To address these challenges, updated flood assessment methods incorporating future hydrological scenarios in a simplified way could be useful. Conservative evaluations of retention capacity, non-regulated spillways, erosion-resistant measures on downstream slopes and other methods are recommended as potential measures to enhance safety. These strategies aim to mitigate the risks posed by extreme inflows, ensuring resilience against the heightened uncertainties of climate-induced events while maintaining robust flood safety standards.
