Program: Integrated Natural Resources Science (INATURES) Program
element 2/task 2.5:
BACKGROUND NARRATIVES
Project objectives and strategy: Based on process study information
from other INATURES projects, the USGS Surface-Water Integrated Flow and
Transport two-dimensional hydrodynamic/transport model (SWIFT2D) has been
applied to the mixed sheet flow, canal, and tidal regime at the eastern
Everglades/Florida Bay interface. This model is available to investigate
flows and flow distributions under current conditions and to test and evaluate
hypotheses pertaining to recommended restoration scenarios. All relevant
forcing functions having a potential impact on restoration decisions will
thus be concurrently and conjunctively treated in a consistent and rigorous
mathematical/numerical model framework. The findings of all restoration
initiatives and process studies will thereby be synthesized for ease of
management evaluation of restoration plans resulting in improved decision
making. Less information is available in the Whitewater Bay area, and field
studies are underway to determine flows through some major creeks near
the Whitewater Bay area. Expanding the SICS model grid westward into this
area will provide valuable insight into the interaction between the flows
to the Shark River Slough Basin and the Whitewater Bay area. This expansion
will coordinate the field data being collected on the west coast with all
the information
Potential impacts and major products: The most visible product
of this project that the Water Resources Investigations Reports (WRIR).
The importance of the model area to restoration, the selection of the model
boundaries, and the field velocity measurements will be discussed in the
initial sections of each report. The flow model development, followed by
the determination of salinity transport will then be described. The final
report sections will be on approximating flow at the Florida Bay coast
based on water levels. By extending the model westward, a complete representation
of coastal flows can finally be constructed. The information on computed
flows and flow distributions at the coast to be used as boundaries in ACOE
models is a major product. The numerical model input data is also a product
that can be used by any agency interested in computing a flow scenario
for the area. The raw data itself, including the velocity, elevation, vegetative
types, and evapotranspiration information will be available to all interested.
Collaborators, Clients: The model results in the western area
will allow better computations of total water budgets by the South Florida
Water Management District and Everglades National Park. The Army Corps
of Engineers is developing flow models in the area which will also make
use of this projects results. Future studies by the Biological Research
Division of the USGS will rely on flow data produced by this model.
WORK PLAN
FY 1999 activities: Reconnaissance of the Whitewater Bay and
Shark River Slough will begin early in FY 1999. Locations for flow measurements,
starting in January 1999, will be chosen and compilation of existing flow
data will begin at major river outflows to the west. The report on the
eastern model area will be published in October 1999. By May 1999, A preliminary
model, using rainfall, ET, and boundary data derived from existing process
studies and new measurements will be developed. Refinement of this model
will be accomplished through October by comparison with field data and
incorporation of smaller scale topographic features.
FY 1999 deliverables/products: The model results will be freely
accessed by all cooperating agencies. The report from the first SICS study
area will be available in 1999.
FY 1999 outreach: Presentation of model results, in the appropriate
Ecosystem symposium forums and at cooperating agencies, will continue throughout
FY 1999.
ACCOMPLISHMENTS, OUTCOMES, PRODUCTS, OUTREACH
FY 1998 deliverables, products completed: The compiled and interpolated
land elevations for the model have been provided to the Army Corps of Engineers,
as well as coastal flow values.
