TIME-DEPENDENT MILD SLOPE EQUATION FOR RANDOM WAVES

Yasuhiro Kubo, Yasuo Kotake, Masahiko Isobe, Akira Watanabe

Abstract


A time-dependent mild slope equation is derived to simulate the deformation of irregular waves due to refraction, diffraction and breaking. It is based on Berkhoff's mild slope equation, but the resulting model is capable of simulating the time evolution of irregular wave profiles. The validity of the model is verified through comparisons with experimental data in a wave flume. Application examples for two-dimensional problems are given.
