Project Summary Sheet
Fiscal Year 2004 Study Summary Report
Study Title: SICS and TIME Model Linkages and Development in Support of Everglades Restoration (Formerly Two Projects; SICS/TIME Surface Water and SICS/TIME Ground Water)
Location (Subregions, Counties, Park or Refuge): Southern Everglades and Florida Bay; Miami-Dade County; Monroe County; Everglades National Park
Associated / Linked Studies: Across Trophic Level System Simulation (ATLSS); Canal and Wetland Flow/Transport Interaction, Effect of Wind on Surface Water Flows; Everglades ET measurement and modeling, Flow Velocity and Water Level Transects; Freshwater Flows into Northeastern Florida Bay; Geophysical Studies of the Southwest Florida Coast; Ground Water Flow and Transport for the SICS and TIME Models; Groundwater-Surface Water Interactions and Relation to Water Quality in the Everglades; High Accuracy Elevation Data Collection; High-Resolution Bathymetry of Florida Bay; Southwest Florida Coastal and Wetland Systems Monitoring; Vegetative Resistance to Flow in the Everglades; Everglades Coastal Gradients Study; Florida Bay, Florida Keys Feasibility Study.
Overview & Objective(s): This investigation makes use of the SWIFT2D two-dimensional surface-water model and the SEAWAT three-dimensional ground-water model to represent flow and transport in the southern Everglades. This successful production of an operation model can be primarily attributed to this projects allocation of the necessary resources and time. Similar efforts outside the USGS have typically been terminated before successful completion. The SICS model, constructed first, represents the southeast coastal region interface with Florida Bay. SWIFT2D and SEAWAT are coupled, allowing leakage to be represented along with salinity transfer. In order to represent regional restoration scenarios, the SICS model has been linked via boundary water levels to the regional South Florida Water Management Model. This linkage allows the simulation of restoration scenarios, defined by the SFWMM, in the SICS area. The same modeling system is in the process of being expanded to the west and north to include the TIME domain. This encompasses more of the structural controls in the area and allows for the representation of Shark Slough flows. The SICS model output has been coupled to components of the ATLSS ecologic modeling suite, in order to supply the necessary hydrologic information for determination of fish population dynamics.
Status: The SICS model has been documented in several publications which describe the surface-water representation, a user's manual for the surface-water model, the coupling to the ground water, and the linkage to the SFWMM. The coupled SICS model has a seven-year simulation period producing good representations of field data. Several base scenarios created by the SFWMM have been implemented in the SICS model, demonstrating the utility of the linkage. The TIME model is currently being tested in coupled configuration. The SICS scenarios are used in ATLSS simulations, which are described in a conference paper.
Recent Products: The documentation of the SICS surface-water model has been published as WRIR 03-4287 Two-dimensional hydrodynamic simulation of surface-water flow and transport to Florida Bay through the Southern Inland and Coastal Systems (SICS) and the coupling to the ground-water model as OFR 04-1097 "Simulation of integrated surface-water/ground-water flow and solute transport for a coastal wetland and adjacent marine estuary".
TWRI Book 6, Chapter 1, Section B A model for simulation of surface-water integrated flow and transport in two dimensions: SWIFT2D user's manual is the user's manual for the SWIFT2D code and OFR 2004-1195 Assigning boundary conditions to the Southern Inland and Coastal Systems (SICS) model using results from the South Florida Water Management Model (SFWMM) describes the linkage of SICS to the SFWMM.
The SICS/ATLSS coupling has been described in a conference paper at the International Environmental Modeling and Software Society (IEMSS) 2004 conference.
Planned Products: A presentation and abstract on the SFWMM linkage will be given at the November 2004 GSA conference.
The SICS/ATLSS coupling will be discussed in an article in the IEMSS Journal.
The NCER conference in December 2004 will feature several extended abstracts and a fact sheet about SICS, TIME and ATLSS.
A user's manual for the modified wetland application of the SWIFT2D code should be published by the end of the calendar year.
A document describing the TIME model development and code modifications is planned for completion in FY 2006.
Further SICS and TIME restoration scenarios will be posted on the CERP web site along with technical descriptions.
Specific Relevance to Information Needs Identified in DOI's Science Plan in Support of Ecosystem Restoration, Preservation, and Protection in South Florida (DOI's Everglades Science Plan) [See Plan on SOFIA's Web site: http://sofia.usgs.gov/publications/reports/doi-science-plan/]:
This coupled numerical model will continue to be a crucial decision support tool. The quantity, timing, and distribution of clean fresh water needed to restore the South Florida ecosystem is a primary concern, and can only be addressed by numerical models which represent the controlling factors and can represent proposed scenarios. The SICS/TIME modeling effort is the only functioning numerical representation of this critical geographic area; simulating the effects of possible restoration scenarios. These scenarios will assist in planning actions to restore, protect, and maintain natural resources on DOI lands in South Florida, allowing a prediction of the results of the planned actions. The coupling of the SICS output to the ATLSS ecologic models allows the testing of the action scenarios on the recovery of South Florida's threatened and endangered species. All these capabilities makes the SICS/TIME effort essential to Ecosystem Restoration.
