Abstract: Leakage is common for reservoir dams which not only affects the project benefits, but also causes serious hidden risks, can even lead to a dam break. Locating the leakage and its passage is the basis for further treatment which is key to ensure the safe operation of reservoir dams. At present, there are many leakage detection methods with their own applicability and limitations, and are restricted by site condition, environmental condition and geological conditions. Suitable methods should be selected based on method characteristics and site conditions, to achieve better detection effect.

Key words: reservoir dams, leakage defect, detection methods
