Abstract: A series of laboratory experiments were performed, simulating the propagation of idealised dam-break waves over movable beds in the presence of an initial bed discontinuity at the dam location. The experiments were performed in a new dedicated flume. They were exploited during the IMPACT European project as a benchmarking procedure for the validation of a range of simulation models. This paper presents the flume and the experiments. Observations are then faced against simulation outputs using an original one-dimensional multi-layer shallow water model.
