A set of computational model tests was carried out to simulate high velocity bore impact on a vertical wall. The results were compared to a series of experimental tests conducted at the O.H. Hinsdale Wave Research Laboratory, large wave flume (LWF) at Oregon State University (OSU) [1]. Experimental tests included scaled tsunami experimental bores that traveled over a flat bottom [2]. The experimental bores were generated by solitary waves propagating over a sloping beach and breaking onto a flat reef [3]. After traveling through the reef portion, the generated bore impacted a vertical wall. In the experiments the resulting forces and pressures on the wall were measured. The aim of the study was to computationally regenerate the experimental bore flow and its impact on the vertical wall. Two computational domain setups were tested: 1) a dam break [3–8,10–16] and 2) a new approach, in which constant height and velocity water inflow was defined at the inlet to the domain. The two numerical approaches were compared to the LWF experimental data [3].
