Numerical Study of Some Wave-Breaking Problems by a Finite-Difference Method

Abstract

The finite-difference method TUMMAC-Vbk developed for 2D breaking waves is improved so that higher-Order accuracy is achieved in a variable mesh system. This numerical tool is used to investigate into two wave breaking problems, i.e., wave breaking on a shallowly submerged obstacle and on a bump. The comparison of the simulated results with experiments shows good agreement.
