Abstract

Abstract

A well-mixed ultra-shallow water storm surge model with eddy viscosity which is a physically acceptable arbitrary function of depth is developed.The empirical linear law of bottom friction is derived,which provides a functional relationship between the eddy viscosity and the turbulence damping coefficient.An approach for establishing asymptotic vertical profiles of the eddy viscosity is proposed.Currents are estimated and compared with ones in the case of constant eddy viscosity.A theoretical estimation of time lag between the surge and the wind stress in a stage of quasistationary development of the surge shows agreement in order of magnitude with observed data.
