A series of experiments have been carried out in the large wave flume (LWF) at Oregon State University to quantify tsunami bore forces on structures. These tests included “offshore” solitary waves, with heights up to 1.3 m, that traveled over a flat bottom, up a sloping beach, and breaking onto a flat reef. Standing water depths on the reef varied from 0.05 m to 0.3 m. Resulting bores on the reef measured up to approximately 0.8 m. After propagating along the reef, the bores struck a vertical wall. The resulting forces and pressures on the wall were measured. The test setup in the LWF is described, and the experimental results are reported. The results include forces and pressure distributions. Results show that the bores propagated with a Froude number of approximately 2 and that the forces follow Froude scaling. Finally, a design formula for the maximum impact force is given. The formula is shown to be an improvement over existing formulas found in the literature.read more

Experimental study on the hydrodynamic impact of tsunami-like waves against impervious free-standing buildings
TL;DR: Tsunamis, landslide-generated waves, and dam failures are rare, but highly destructive phenomena, associated with extreme loading on infrastructure as discussed by the authors, and recent events showed that specific measu...

Numerical study of PPE source term errors in the incompressible SPH models
TL;DR: In this article, a mixed source term formulation was proposed to predict the fluid impact pressures and forces, both in the magnitude and in the spatial and temporal patterns, in a wider range of fluid impact situations in order to quantify the numerical errors associated with different formulations of the PPE source term in incompressible SPH.

Tsunami Surge Forces
TL;DR: In this paper, the front part of a surge on a dry bed is examined in detail and a theory developed, in conjunction with the waterwedge theory, to predict the forces occurring when such a surge strikes vertical wall.
