Three-Dimensional Flow Simulation in Estuaries,

Abstract

The model described in this paper is based upon numerical integration of the flow equations which simulate the water movements casued by tides, wind and pressure differences and upon numerical integration of the advective diffusion equation representing the movements of salt and temperature. The model neglects vertical accelerations, but not vertical velocities, and includes and approximation for the subgridscale effects by introduction of mass and momentum exchange coefficients. These coefficients are dependent upon the Richardson number and vertical velocity gradients, The computation method is tested on an estuary and the results of the simulations are presented in graph form.
