Simulation of scouring in front of an impermeable vertical breakwater using the RANS-VOF numerical model
This study presents the application of the RANS-VOF based model for scouring simulation with different wave condition in front of vertical breakwater.

This study presents the application of the RANS-VOF based model for scouring simulation with different wave condition in front of vertical breakwater. An empirical sediment transport formulae of Bailard (1981) was applied to estimate the bed profile change. Additional terms of bottom shear stress were included in the momentum equations and surprisingly seem necessary to produce a physical scouring/deposition pattern. Validation results showed that the present model is very accurate in the prediction of near bottom velocity. The numerical bed-profile was also consistent to experimental data. It was observed that different wave conditions produce standing waves with different characteristics in front of the breakwater. This consequently develops different scouring pattern at the bottom. As the size of incoming wave increases, the size of scouring trough and deposition ridges also increase. |
