Abstract
The system of shallow water waves is one of the classical examples for nonβlinear, twoβdimensional conservation laws. The paper investigates a simple kinetic equation depending on a parameter Ο΅ which leads for Ο΅ β 0 to the system of shallow water waves. The corresponding βequilibriumβ distribution function has a compact support which depends on the eigenvalues of the hyperbolic system. It is shown that this kind of kinetic approach is restricted to a special class of nonβlinear conservation laws. The kinetic model is used to develop a simple particle method for the numerical solution of shallow water waves. The particle method can be implemented in a straightforward way and produces in test examples sufficiently accurate results.

The present paper makes use of a wave equation formulation of the primitive shallow water equations to simulate one-dimensional free surface flow. A numerical formulation of the boundary element method is then developed to solve the wave continuity equation using a time-dependent fundamental solutio
