Abstract

The Euler equation of fluid motion is integrated in the vertical direction by assuming a hyperbolic cosine distribution of pressure, As a result, quasi-linear hyperbolic equations governing the wave motion above a solid bed are obtained. The equations are then applied to describing the wave transformation over a submerged plate. An algorithm based on the method of characteristics is developed in the numerical computation. The wave reflection and transmission coefficients computed under various conditions are compared with the experimental data, and the overall agreement is found to be fairly satisfactory.
