NUMERICAL MODELING OF HARBOR RESPONSE TO WAVES

Both short (up to 25-sec period) and long (2S-sec to 10-min period) wa ves can cause damaging conditions in harbors. Harbors of all sizes are affected, ranging from small recreational harbors to large commercial harbors. The U.S. Army Corps of Engineers has many years of experienc e with harbor wave concerns and has developed powerful and complementa ry numerical and physical modeling tools. The CE numerical model descr ibed in this paper, can be used effectively to answer many engineering questions about harbor wave response. Two examples are presented of n umerical model studies to evaluate the relative level of short wave pr otection provided by different breakwater configurations. Two addition al examples illustrate model applications to evaluate long wave-induce d harbor oscillations.
