This report constitutes a technical review and critical appraisal of present techniques of water quality modeling as applied to estuaries. Various aspects of estuarine modeling are treated by a selection of scientists and engineers eminent in the field, and these essays are supplemented by discussions from technical conferences held during the course of the report's preparation. Topics discussed include one-, two-, and three-dimensional mathematical models for estuarine hydrodynamics, water quality models of chemical and biological constituents including DO, BOD, nitrogen forms, phytoplankton and general coupled reactants, models of estuarine temperature structure with special attention given the modeling of thermal discharges, and the principles and applicability of physical models in estuarine analysis. Also included is a review of solution techniques, viz. analog, digital and hybrid with a detailed discussion of finite-difference methods, a brief survey of estuarine biota and present biological modeling activities, and a collection of case studies reviewing several past estuarine modeling projects. Conclusions about the existing state of the art of estuarine modeling and recommendations for future research by EPA are advanced throughout the report and are summarized in the final chapter.
