Waves and Run-Up Generated By a Three-Dimensional Sliding Mass

Large-scale laboratory experiments were conducted measuring the waves generated by two wedge-shaped bodies sliding down a 2:1 slope. The waves near the body propagating offshore and the run-up generated on the slope were measured. It was determined that the maximum “draw-down” wave over the body was essentially generated before the body had moved more than one-half its length downslope. In addition to shape, the important parameters that controlled the run-up were the initial submergence and the initial acceleration of the body.
