A Numerical Solution Method for Nonlinear Shallow Water Waves (Second Report)

Abstract

The two-dimensional finite-difference method TUMMAC-III developed in the first report is applied to three problems of steep regular waves interacting with obstacles, i.e., run-up on a beach, deformation and breaking on a sandbar and diffraction by a rectangular floating body. Experiments are undertaken for these problems and the wave profiles and pressures on the body are compared with the computation. The agreement is satisfactory as far as the waves before breaking are concerned.
