Physical, Chemical, and Biological Characteristics of the Charlotte Harbor Basinand Estuarine System in Southwestern Florida. A Summary of the 1982-89 U.S. Geological Survey Charlotte Harbor Assessment and Other Studies

摘要

The Charlotte Habor estuarine system, having a surface area of about 270 squaremiles, average about 7 feet in depth and is connected to deep water of the Gulf of Mexico through several passes and inlets between barrier islands. Freshwater and tidal flushing transport nutrients and other constituents from the basin through the estuary into the gulf. Flushing characteristics were evaluated using a two-dimensional hydrodynamic model. The model indicated that the time required to flush injected dye (simulated) from some subareas of the harbor was longer for reduced freshwater inflow than for typical freshwater inflow.
