Description 1177-1182
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 velocities obtained
from the model and the laboratory experimental resultsare compared. The model
without the morphology feedback provided good correlation with the measurements
for case of low wave energy, whereas for the case of a moderately high wave
energy, due to significant variations in the bed morphology, the model
under-performed towards the later part of the simulation. However,
incorporating a modified bathymetry considering the variation in the bed
morphology, the model results were reasonable.
