IMPROVED BOUNDARY CONDITIONS TO A TIME-DEPENDENT MILD-SLOPE EQUATION FOR RANDOM WAVES

Toshimasa Ishii, Masahiko Isobe, Akira Watanabe

Abstract


The offshore and side boundary conditions to a, time-dependent mild slope equation for random waves are improved to introduce given incident waves into and extract reflected waves from the computational domain with reduced computational time and storage size. The resulting numerical model is applied to calculate the wave field, nearshore current, and bottom topography change around a detached breakwater.

Keywords
