COOPERATIVE LINKING OF NUMERICAL MODELS FOR COASTAL WETLAND PLANNING

摘要

The coastal interface of northeastern Florida Bay with the southeast portion of Everglades National Park is of interest to water managers in ecological restoration, both inland and offshore. In order to represent the dynamic and interconnected surface-water and ground-water processes of this area, the US Geological Survey developed the Southern Inland and Coastal Systems (SICS) model by linking the two-dimensional dynamic surface-water code SWIFT2D with the variable-density ground-water flow code SEAWAT. Application of the coupled code to the SICS area has shown it can represent water-level fluctuations, leakage, discharge, salinity, and inundation patterns. In order to allow the SICS model to represent different water-supply scenarios, the model is being coupled with a regional model developed by the South Florida Water Management District and the U.S. Army Corps of Engineers. Surface water flows into the SICS area, simulated by the regional model for various water-supply scenarios, yield boundary conditions for simulations that provide insight into the effects of modifying the larger scale hydrologic system.
