Search for: [Abstract = "In the method of solution, we use a simplified perturbation analysis and suitable applications of Green`s integral theorem in the two fluid regions produce first\-order reflection and transmission coefficients in terms of integrals involving the shape function describing the bottom undulations and solution of the scattering problem involving a submerged vertical wall present in the lower fluid of uniform finite depth. For sinusoidal bottom undulations, the first\-order transmission coefficient vanishes identically."]
