Abstract : The aim of this paper is to describe a computational method for determining traveling edge waves along a straight infinite beach with a cylindrical, not necessarily plan bottom. The determination of a periodic edge waves along a straight infinite beach can be formulated as a 2-dimensional eigenvalue problem for a generalized wedge. A least squares boundary collocation method for computing the lower discrete eigenvalues is described, with an error estimate for the least eigenvalue. Numerical examples are presented.
