Abstract

A three-dimensional, non-stationary, shallow-water model of wind induced circulation in lakes is formulated. The finite element approach is used for spatial discretization. Uniform elements /triangular prisms/ with the simplest possible shape functions are used. Since the model is linear and has a nevolutionary form.spatial discretizationyields a linear system of ordinary differential equations. Apt implicit, one-step scheme is applied for time, integration. The obtained system of algebraic equations is solved iteratively.

Partition into elements is supported by a heuristic algorithm of surface triangulation.
