Tides and Inflows in the Mangrove Ecotone (TIME) Model Development
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 natural and regulatory factors contribute to influence 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.
TIME Workshop in Key Largo
USGS Process-Study and Model-Support Planning Workshop for the Tides and Inflows in the Mangroves of the Everglades (TIME) Model Development Project
On June 27-28, 2000, a two-day workshop was held to facilitate the planning, coordination, and interaction of U.S. Geological Survey (USGS) project activities toward support and development of the Tides and Inflows in the Mangroves of the Everglades (TIME) model and its integration with ecological models. Participants from more than twenty Biological Resources, Geologic, National Mapping, and Water Resources Division projects, conducting research and monitoring efforts in the southern Everglades as part of the USGS South Florida Ecosystem Program, attended the planning workshop. The principal objective of the workshop was to design and develop a coordinated plan and implementation schedule to provide hydrological and ecological process-study findings and field-monitoring results for integration into the model development. Four workshop teams were formed to make planning recommendations for integration of process-study findings and monitoring results in the areas of 1) topography and landscape characterization, 2) flows, tides, salinities and forcing functions, 3) groundwater system and surface-water interactions, and 4) modeling hydrological and ecological processes. The workshop plan is expected to help guide ongoing research and monitoring efforts toward fulfilling TIME model-development needs.
