|Abstract:||The diffraction of water waves by a submerged fixed inclined plate is modelled using the finite element method (FEM). Wave induced pressures and forces on the submerged fixed inclined plate due to incident monochromatic waves are analysed using the finite element model. The fluid domain is discretised using 8 node isoparametric elements with 3 node quadratic line elements on the free surface, bed and radiation boundaries. The accuracy of the numerical technique is demonstrated by comparing the FEM results with the analytical solution obtained by long wave solution for a thin submerged fixed horizontal plate in shallow water. The horizontal and vertical force coefficients are computed for various wave periods and inclinations of the plate. The reflection and transmission coefficients are also computed and presented for various submergence depths. The possible use of the submerged inclined plate as a breakwater and its advantages over the horizontal plate are discussed. © 1994.|
