Numerical simulation of spectrum wave propagating in pseudo three dimensional wave basin

The convention method of berthing stability study by physical scaled model was replaced by purely numerical model based on modified Boussinesq type wave equations in the paper. Directional spectrum wind wave was generated in pseudo three dimensional numerical wave basin. In front of vertical walls, typical reflection coefficient of 0.80 was introduced, and around the sloped breakwaters the reflection coefficients of 0.50~0.60 were applied. The calculation domain was a real fishing port with directional wind wave incoming from Southeast, and South, Southwest. By purely numerical method, the berthing stability was studied in accordance with the Code of Hydrology for Sea Harbor, China (“the Code”). It is concluded the numerical model is of satisfactory accuracy and can be of engineering reference value in the design and planning of coastal structures and harbors.
