Abstract : Physical models of rivers, estuaries, and bays have been utilized for years to model the hydrodynamics of those bodies of water. However, physical models are more limited in addressing water quality problems which have received more emphasis in recent years. With the advent of digital computers over the past 20-30 years it has become feasible to develop numerical models to determine the chemical and biological changes that occur if the physical character of an existing estuary is changed, e.g. by dredging, diking, or permanently changing the freshwater inflow. Solving such problems requires predictive models to compute the distribution of currents and circulations in the water body. These results are then used to predict the distribution of quality parameters. Although both three-dimensional
