Abstract : The theory was derived for the dynamic pressure trace at the sea bottom and the surface waves created by a ground effect machine of rectangular planform moving with constant velocity over quiescent water of finite depth. The numerical results for the dynamic pressure trace at the sea bottom are presented. Because of convergence difficulties, the numerical calculation of the exact surface wave contour was not completed. However, the convergence characteristics were improved by deforming the path of integration. Further effort is necessary in order to obtain the numerical results for the surface waves. For very shallow water, solutions for both the pressure trace and surface wave contour were obtained. (Author)
