ABSTRACT
ABSTRACT: The main cause of rockfill and embankment dams failure is overtopping. The dam failure mechanisms are complex and some of the involved parameters are difficult to obtain by physical testing, such as the seepage flow net into the shell. In recent years several numerical models were developed to better understand these failure processes. The main objective of this research was to study the flow pattern around the slope by means of numerical models, in order to simulate rockfill dams behavior in overtopping scenario. A time dependent flow pattern with vorticity was observed around the downstream slope.
