2D LARGE-EDDY SIMULATION OF WATER-WAVE IMPACT DURING VIOLENT OVERTOPPING EVENTS

Xin Lu, Qingping Zou, Dominic E Reeve

Abstract


In this work a newly developed numerical model was employed to conduct comprehensive numerical modeling to investigate the waves overtopping at a vertical seawall, and the associated impact pressures with a certain breaking wave condition. The objective is to qualitative and quantitative understanding of individual violent wave overtopping events on seawalls.
