Wave Boundary Layer
Tsunamis are difficult to study experimentally due to the large scales involved. Therefore, much tsunami research have been done numerically using potential flow models. These, however, require empirical breaking models and do not resolve the boundary layers. In this work we use CFD to simulate the run-up of full-scale tsunami waves. By using CFD it is possible to resolve shorter dispersive waves, wave breaking and tsunami-induced boundary layers. From the simulated results conclusions on run-up scenarios are drawn, and a new method for predicting tsunami-induced bed shear stress is proposed, which can easily be implemented in potential flow models.
