Complementary approximations to wave scattering by vertical barriers

Porter, R. / Evans, D.V.

Scattering of waves by vertical barriers in infinite-depth water has received much attention due to the ability to solve many of these problems exactly. However, the same problems in finite depth require the use of approximation methods. In this paper an accurate method of solving these problems based on a Galerkin approximation is presented. It is shown how highly accurate complementary bounds can be computed with relative ease for many scattering problems involving vertical barriers in finite depth and also for a sloshing problem involving a vertical barrier in a rectangular tank.
