Modelling of wave propagation over the submerged sand bar using SWASH

A non-hydrostatic numerical model ‘SWASH’ (Simulating WAves till SHore) is used to study the wave propagation over a submerged sand bar in a wave flume. The SWASH model is calibrated and further used to validate the wave propagation for two different cases. The wave heights and wave induced velociti...
