TRANQUILITY SIMULATION FOR FISHING PORT APPLYING TIME-DEPENDENT MILD SLOPE EQUATION FOR RANDOM WAVES

* ** *Yoshio OHBA, Masaaki SAKURABA and Toshirou TERADA

This paper presents the application of a time-dependent, mild-slope equation for random waves to tranquility simulation for fishing port analysis. This model is able to analyze almost all wave deformation (shoaling, diffraction-refraction, reflection, breaking etc.) caused by multi-directional random waves. It can be used to calculate the wave deformations approximating real phenomena in ports and harbors with the complex shapes. As a practical application, the method was applied to the development of a maintenance plan for the fishing port. The method is also useful for the basic investigation of coastal sediment transport.

Key Words mild-slope equation, numerical simulation, random waves, wave deformation, fishing port
