Introduction: Hydraulic models have been extensively used by the Corps of Engineers over the past several decades for the purpose of determining the optimum design of a proposed coastal structure, the hydraulic effects of a proposed estuarine improvement (such as widening or deepening a channel), or to determine the optimum alignment of a breakwater to provide protection, in either a small or deep-draft harbor. In recent years, Corps model studies have expanded in scope and can now be considered a valuable tool for coastal zone management. Primarily, a hydraulic model is utilized to predict physical parameters of the environment or changes to the environment as a result of dynamic processes. These quantities include currents, wind waves, tides, salinities, temperatures, edge waves, rip currents, tidal flushing, sediment transport characteristics, mass transport, setup, runup, tsunami inudation, nearshore and estuarine circulation; vertical flux of horizontal namentum, channel stability, and normal models of oscillation. Usually the above parameters are sufficient to determine the physical changes in the environment resulting from various plans of coastal zone development; however, even more important to overall coastal zone management, a knowledge of the physical and dynamic characteristics is essential in quantitatively ascertaining the ecological effects of a coastal zone development plan. This paper delineates the results of several model studies (either recently completed or in progress) and attempts to demonstrate their utility for coastal zone management.
