These books are divided into two volumes. The first focuses on estuarine physics and physical processes and interpretations. I have, for the most parts, intentionally downplayed engineering applications to estuaries. It is my bias that a deeper understanding is accomplished with a physical approach, whereas an engineering approach is largely geared toward finding a solution to a problem. Of course, it is not always easy to make this distinction. The second volume is a presentation of physical case studies of several important estuaries, spanning the major geomorphic types. I believe that it can be very useful to all areas of the world. I have consciously strived to be more international to scope in selection of both authors and estuarine case studies.

The Estuary as a Filter contains the proceedings of the Estuarine Research Federation's seventh biennial conference at Virginia Beach, Virginia, in late October, 1983. In five invited sessions, scientists and managers considered the physical, geological, chemical-geochemical, and biological processes involved in the ""filtering"" role of estuaries and reflected on management implications of these matters. Most of their presentations and reflections are included in this book in order to demonstrate what is known and what needs to be explored further. The papers in this volume are grouped as they were presented at the conference. Thus, physical oceanographers begin the work by considering turbulence, mixing, and circulation processes in estuaries. Geologists then examine estuarine sedimentation, including the roles of flocculation and bioturbation in accelerating this process. Chemists and geochemists describe the interactions among and effects of inputs of nutrients, metals, and organic matter into estuaries, and the fate of radionuclides in these systems. Biological and biochemical processes involving surface foam, microbes, sea grasses, and wetlands are considered, along with carefully derived nutrient budgets of selected estuarine regions. Finally, some of the problems facing managers of estuarine ecosystems in three areas of the United States are described, along with the success story of the ongoing rehabilitation of the Thames Estuary in England.

The astronomic tidal circulation in Puget Sound, Washington, is investigated using the Waterways Implicit Flooding Model (WIFM) in two-dimensional, vertically-averaged context. The state of knowledge of general circulation characteristics is presented as a prelude to the numerical modeling investigation. A general tide prediction program had been developed which predicts both tidal evaluations and horizontal currents. Astronomic tidal characteristics are studied on a 70 (horizontal) by 103 (vertical) dimension global grid comprising 7,210 cells with a maximum spatial resolution of 3,750 ft. A 90-sec time-step was employed in all WIFM long-wave simulations resulting in a maximum Courant number of 4.1. Simulated tidal elevations and vertically-averaged currents were calibrated to predicted values for the 16-18 January 1981 spring tide period. Calibrated bottom friction mechanics were verified using the 13-15 January 1981 neap tide period. Simulated results corresponded to predicted values of elevation and current except for some discrepancies in the Southern Basin. Peak current magnitudes were tabulated at existing disposal sites for both calibration and verification of astronomic tide conditions. Meteorological effects and freshwater inflows were not considered. The 11-13 December 1985 extreme spring tide period was also simulated, and maximum current velocities and their associated times of occurrence were tabulated.
