A description of different computational aspects of the use of a three-dimensional finite-difference model of estuaries, bays, and coastal seas. With this model, salinity and temperature distributions can be computed, together with the flow field, then coupled to the flow computations by a complicated equation of state. In the model an approximation for the subgridscale effects is introduced by use of mass and momentum exchange coefficients. The vertical exchanges are dependent on the Richardson number. The computational method is tested on bays and estuaries with widely different characteristics. The results of these experiments are presented in graphic form. It is concluded that effective simulations can be made with the model.
