A critical objective of the south Florida ecosystem restoration effort is to preserve ecological conditions that are consistent with habitat requirements. The duration, timing, and extent of wetland inundation in the southern Everglades have been greatly distorted as evidenced by shifts in biologic and vegetative species. Both regulatory and natural factors contribute to the definition of hydroperiods making their precise evaluation and management difficult. This complexity is particularly problematic in the transition zone between the Everglades wetlands and coastal embayments encompassing the mangrove ecotone where freshwater inflow effects on salinities must also be considered. In order to correctly and sufficiently investigate flow effects on both hydroperiods and embayment salinities neither hydrologic processes affecting flows in the wetlands nor the dynamic effects of external forces such as tides and winds can be ignored. This project entails translation of findings from the Southern Inland and Coastal Systems (SICS) project and extension of the model westward to resolve boundary limitations and to enable concurrent analysis of wetland and tidal response throughout the entire saltwater-freshwater interface zone along the Gulf coast and Florida Bay. Extension of the SICS model westward will require the addition of continuous monitoring stations to supplement data from coastal creek stations and control structures needed to provide boundary conditions as well as the synoptic measurement of flows and water levels in the wetlands for use in model calibration and verification.
This project is focused on further developing, extending, implementing, and using a mathematical model to study the interaction between wetland sheet flows and dynamic forces in the transition zone between the southern Everglades and its coastal embayments. The model will be used to study and evaluate the combined response of hydroperiods in the wetlands and salinities in the mangrove ecotone to inflow alterations. The project effort will include 1) monitoring hydrologic processes and dynamic forces to develop an improved understanding of them individually and of their interaction, 2) translating this information and prior knowledge of processes gleaned from the SICS project into improved empirical expressions and mathematical equations to better represent the processes both individually and collectively, 3) transforming these expressions and their correlation to ecosystem properties into numerical algorithms, 4) integrating these algorithms into an existing numerical model framework, 5) implementing the model to the transition zone of the Everglades that encompasses the mangrove ecotone using collected data to define critical ecosystem properties such as land-surface elevations, vegetative characteristics, etc., 6) calibrating the model using time series of water-level and flow data collected at strategic intermediate internal points, 7) using the model to investigate and quantify the interrelation of wetland and tidal flows in the transition zone in response to real and hypothesized temporal and spatial variations in inflows, and 8) documenting the model implementation and any findings using it that are critical to improved management of the ecosystem.
