Abstract

Laible [2] has implemented a sequential Fortran-77 code for a 3-dimensional surface water flow model. The model uses the Galerkin Finite Element Method (FEM) with triangular elements and linear basis functions to solve the vertically integrated wave formulation of the shallow water equations for surface water elevations in the 2-d horizontal domain. The full 3- dimensional velocity field is subsequently solved for by the Galerkin FEM along the 3rd (vertical) dimension using 1-dimensional linear elements at each of the nodes in the 2-D horizontal mesh. The inclusion of a baroclinic term enables simulation of the internal seiche that develops in lakes under stratified conditions. In this study, the existing code was p
