The authors would like to acknowledge the contributions made by Joseph Smagorinsky to our investigations of estuarine and coastal ocean circulation. It was through his sustained interest that the three-dimensional model described in this article came to fruition. Ample computer resources and a creative research environment were generously made available. A debt ofgratitude is also owed to George L. Mellor for his many substantive ideas concerning the model development and applications. Discussions with H. James Hemng and Lakshmi H. Kantha over many years have contributed signiscantly to our modeling efforts. Support for this work was provided to AFB by the Dynalysis program for Independent Research and Develop ment (IRD) and to LYO by the Visiting Scientist Program of Princeton University/NOAA, Grant 04-7-022-440 17, and by the Office of Sea Grant of NOAA, Grant 8 1-AA-D-0065, Project R/E-3.

N2 - This chapter describes modeling of circulation and mixing in estuaries and coastal oceans. The most crucial factor limiting the development of a truly predictive circulation model is a lack of a comprehensive observational database for model initialization, boundary condition specification, and model result assessment. The estuarine and coastal ocean circulation model (ECOM) model is three-dimensional with prognostic variables being the three components of velocity, temperature, salinity, turbulence kinetic energy, and turbulence macroscale. The density, vertical eddy viscosity, and vertical eddy diffusivity are also calculated. The model responds to surface wind stress, heat flux, and salinity flux and to the specification of tidal forcing, freshwater discharge, and other lateral boundary conditions. The condition under which a given estuary may be well approximated by a two-dimensional vertical-plane model is obtained. It is found that in continental shelf regions in which baroclinic effects are important, fine cross-shelf grid spacing that resolves the baroclinic Rossby radius is required. It is suggested that numerical models with variable grid spacing would be most appropriate in this case.
