Although no direct causeeffect relationship has linked south Florida water management to the sea-grass die-off, hypersalinity, declining shrimp harvests, and water-quaTity changes in the Bay stimulated much of the concern about the condition of the Florida Bay ecosystem reflected in the 1992 Federal Water Resources Development Act, which authorized the Restudy of the Central and South Florida Project. This chapter summarizes some of the research that needs to be undertaken to resolve questions of the potential effects of the plan that arose out of the Restudy, i.e., the Comprehensive Everglades Restoration Plan (CERP)

Hence, on average, the full CERP implementation has a minimal effect on the volume of direct fresh surface water flow into the Bay but a potentially significant effect on the discharge out of Shark River Slough and Whitewater Bay, which eventually reaches the Bay. Additional definition of these flow pathways is urgently needed for modeling of impacts in the Bay.

Dissolved Nutrients Modification of freshwater delivery to the Bay as a result of the CERP has the potential to affect both overall nutrient loadings and the limiting nutrient status of the water by changing the nitrogen:phosphorus ratio in the source waters and ultimately in Florida Bay and the nearby coastal ocean. The consequences of changes in water quality on the Florida Bay ecosystem are a major uncertainty of the CERP.

and ecological modeling, which will be required to evaluate the effect of CERP activities on Florida Bay. Typically, a transient, two- or three-dimensional hydrodynamic model is used to "drive" eutrophication and other water quality models that must be developed to evaluate the effects on the Bay of external forcing functions such as freshwater inflows from the Florida peninsula.

From page 21... ...
Notwithstanding the need for improved numerical techniques and hydrodynamic modeling, a key to successful water quality modeling in Florida Bay will be more reliable information on freshwater inflows and the nutrient balance (Berger, R.C. and Dortch, M.S., USACE Waterways Experiment Station, Personal common., March 2002)

A second modeling option for interfacing the hydrology of the CERP with the hydrodynamics of Florida Bay consists of ongoing model development by the SFWMD of its South Florida Regional Simulation Model (SFRSM) (http://glacier.sfwmd.gov/org/pld/hsm/models/strsm/index.htmI)

may serve as a temporary bridge between CERP forcing functions and Bay response (Hobble et al., 2001~. Development of inferences from models of this type would be useful while the longer and more expensive effort to develop, calibrate and test Florida Bay circulation and water-quality models and hydrologic models linking the land and the Bay is undertaken.
