WebA simple analytical model is presented in this work to investigate reflection coefficients due to the interactions of waves with rectangular submerged obstacles/and submarine trenches. Our intention in this work is to present a simple analytical model to simulate and study water-wave scattering by evaluating reflection coefficients. Further, our challenge is to … WebI would think that each trench would probably have a sub-trench/gully either down the center or along one wall, and that the ENTIRE trench complex would be cut at a slight angle, creating a slope.
