Applicaion of swash on modeling dam-break flow over a triangular bottom sill

Abstract

      This research presents the application of an open source non-hydrostatic wave-flow model on simulating the dam-break flows over a triangular bottom sill, namely SWASH. The numerical results are compared with measured data obtained from the laboratory experiment which was conducted by S.Soares-Frazão (2007). On overall, the model reproduces the measured flow in the experiment very well. The propagated time and the water levels agree well with the results indicated in the experiment. The accurate simulation of the propagation process provides a good estimation of measured flow on the real experiment. The creaated reflex waves in the propagating procedure are also significantly captured.
