Abstract:
This study shows the validation of a new numerical scheme with hydraulic experiment. The proposed scheme is a new computational scheme to solve shallow-water equations for surface waves shoaling on a slope. Experiment was carried out in a wave tank set on an oscillating bed, which can be moved, uniformly equal in both directions. Used flume had a flat bed of 50.5 cm and having a constant slope of 11.30 in one end whereas the other end is fixed with a vertical wall. As initial condition, water depth was 2cm, wave period was 3.5 s and the movement of the oscillating bed was 6 cm. From the comparisons of the time variation of the moving boundary and the water level along the tank, numerical computation was found to provide good agreement with laboratory experiments.
