Refraction of shallow water waves: The combined effect of currents and underwater topography

Robert S. Arthur

Abstract

A solution is given for determining the refraction effect according to Fermat's Principle for the case of shallow water waves moving in any given distribution of current and depth. Application is made to an analytic model of an intense rip current, and the results are compared to actual rips.
