Application of An Integrated Modeling System for Estuarine and Coastal Ecosystems to Indian River Lagoon, Florida

摘要

A CH3D-based integrated modeling system UF-CH3D-IMS has been developed and successfully applied to Indian River Lagoon, Florida. The UF-CH3D-IMS consists of models for the following processes: hydrodynamics/salinity (H/S), waves/sediments (W/S), water quality (WQ), light attenuation (LA), and submerged aquatic vegetation (SAV). These component models have been developed using the same boundary-fitted curvilinear grid system used by CH3D, a 3-D curvilinear-grid hydrodynamics model. All the component models as well as the integrated model (except the SAV model) have been applied to the Indian River Lagoon and validated with extensive field data collected in 1998. The validated integrated model will be used by the St. Johns River Water Management District (SJRWMD) as the Indian River Lagoon Pollutant Load Reduction (IRLPLR) model to determine pollutant load reduction goals (PLRGs) for various segments of the IRL. The integrated modeling system could be applied to determine the PLRG, the Total Maximum Daily Load (TMDL), and the Minimum Flow and Level (MFL) for various estuaries and rivers.
