Numerical Analysis of Combined Refraction and Diffraction of Waves

Refraction and Diffraction combination of Waves, is very important and applicable
problem in coastal engineering (e.g. for designing break - water). However, formulation
of this phenomen and numerical solution is very difficult.
In this study, a numerical algorithm based on the mild Slop sea bed theory is
presented to obtain the appropriate governing equations of combined Refraction Diffraction.
Also, a software has been prepared to solve these equations by finite
difference method in time domain. Finally comparison of the differents results is shown.
