TWO-DIMENSIONAL ANALYSIS OF WAVE TRANSFORMATION BY RATIONAL-APPROXIMATION-BASED, TIME-DEPENDENT MILD-SLOPE EQUATION FOR RANDOM WAVES

Toshimasa Ishii, Masahiko Isobe, Akira Watanabe

Abstract


The method for determining coefficients in the rational approximation is improved and a numerical method is developed for application of time-dependent mild-slope equation for random waves to two-dimensional wave fields. The validity of the method is verified through comparisons with analytical solutions in typical situations and an experimental result of wave transformation around a man-made island on a uniform slope.
