Water availability and the processes by which it moves are critical to a wetland's success, where success is measured in terms of the quantity and quality of functions provided by the wetland. A quantitative understanding of wetland hydrology and hydraulics (H & H) is essential for effective wetland evaluation, restoration, creation and management. As a consequence, analytical tools are needed. Recent work within the U.S. Army Corps of Engineers Wetland Research Program (WRP) has focused on the development of numerical models to study H & H processes within a variety of wetland types. The purpose of this paper is to describe the H & H modeling to date, and to present the results of an initial application to the Cache River, Arkansas.
