Abstract: Most dams leak to an extent. Continuous monitoring and timely rehabilitation is the strategy always adopted to ensure dam safety. In this paper, the innovative method, namely Willowstick method is introduced. By identification, mapping and modelling electric current flow paths through the subsurface, individual water paths are traced and the seepage model is determined. The Willowstick method is helpful in asset management and development of rehabilitation measures. As well, some application cases are given, for reference.
