The coastal environment of
south Florida has shown signs of ecological deterioration that is attributed to
changes in freshwater inflows due to urban development, water management
practices, and corresponding increases of salinity and nutrient content in
estuarine waters. With plans to improve water levels and historic flow-ways in
the Southern Golden Gate Estates (Picayune Strand) area north of Tamiami Trail
to more natural conditions, changes are expected in the amount, timing, and distribution
of freshwater discharge through bridges and culverts under US-41, altering
current conditions in the wetlands and estuaries to the south. Hydrologic
information throughout the Ten Thousand Islands and adjacent ecosystems is
critical to the development of restoration strategies and for the evaluation of
restoration results. With the implementation of the CERP projects "Picayune
Strand Hydrologic Restoration project" and "Tamiami Trail (US-41) Culvert
project", there is a need to determine current hydrologic conditions in areas
south of US-41 (Figure 1). These areas will be greatly impacted by these CERP
projects currently underway. There is little hydrologic information throughout
the wetlands and estuaries within the study area that could be used in the
construction and calibration of the MIKESHE subregional model currently being
constructed under the auspices of the CERP Southwest Florida Feasibility Study.
There is a critical need for information on freshwater flows across the Trail,
ground-water information (including Specific Conductance/salinity) within the
marshes south of the Trail, flows at or near the mouth of tributaries, water
level, and salinity data throughout the area. The results of this study will provide information that
currently does not exist on freshwater flows and salinity trends, effects of
weather systems on flow patterns, and on how SGGE and Tamiami Trail Culverts
restoration projects affect freshwater inflows and water quality of the
estuarine ecosystem within the Ten Thousand Islands area.

objectives of this study are:
develop flow calculation techniques for bridges and culverts under US-41, between
Carnestown and County Road 92. First year focusing on the section between
Faka-Union Canal and County Road 92, expanding east to State Road 29 in
the second year of the study.
provide support to on-going CERP and DOI studies populating hydrologic
databases that can also be used by other federal and state agencies,
universities, and local institutions conducting studies in the area.
Additionally, other federal
and state agencies, universities, and local institutions conducting research in
the area will be give access to all the information generated though this
Relevance to Major Unanswered Questions and Information Needs Indentified:
This project is directly tied
to the Monitoring and Assessment Plan (MAP), performance measures (salinity
distributions), hydrodynamic model development and verification (MIKESHE and TIME/SICS
expansion), and will provide baseline information on flows and salinity
throughout the estuaries within the Ten Thousand Islands area.
Additionally, this effort is
linked to projects listed in the DOI Science Document and to issues listed in
the USGS Science Plan in Support of Everglades Restoration (Restoration goals)

timing, and distribution of flows across Tamiami Train and into the coastal
environments of the Ten Thousand Islands, and monitoring the ecosystem response
goal 2A, "Habitats, Landscapes, and Ecological Processes", by providing pre and
post restoration information on flow across Tamiami Trail. This information is
necessary to link ecological response to hydrologic changes.

efforts within the Picayune Strand and the Ten Thousand Islands areas. Discharge will be made available for
all bridges and culverts across Tamiami Trail from State Road 29 to County Road

Task Summary and
This task is designed to quantify
freshwater discharge across Tamiami Trail, and provide necessary boundary
information for the development and calibration of hydrologic models for the
areas to the north and south of Tamiami Trail (Figure 1). The data can be used
to calibrate the MIKESHE sub-regional model currently being constructed over
the study area, and any other model developed for the wetlands and estuaries
within the Ten Thousand Islands area to the south of Tamiami Trail.
The objectives of this study
are (1) To develop flow calculation techniques for bridges and culverts
under US-41, between Carnestown and County Road 92. First year focusing on the
section between Faka-Union Canal and County Road 92, expanding east to State
Road 29 in the second year of the study; and (2)
To provide support to on-going CERP and DOI studies populating
hydrologic databases that can also be used by other federal and state agencies,
universities, and local institutions conducting studies in the area.
Work to be undertaken during the proposal
year and a description of the methods and procedures:
A maximum total of four flow
stations will be installed at bridges west of Faka-Union canal, for the
collection of stage, velocity, discharge, salinity (or Specific Conductance),
and temperature data. Discharge measurements with an Acoustic Doppler Current Profiler (ADCP) instrument will be made at these and all other bridges (or
culverts) along the Tamiami Trail, between Carnestown and County Road 92.
During the second year of the study, work will be expanded east of Faka-Union
Canal to State Road 29.
of a maximum total of four flow stations at bridges of Tamiami Trail between
Faka-Union canal and County Road 92 for the collection of stage, velocity,
discharge, salinity (or Specific Conductance), and temperature data.
- Begin discharge measurements with an Acoustic Doppler Current Profiler (ADCP) or comparable instrument at these and all
other bridges (or culverts) along the same section of Tamiami Trail.
- Start developing velocity calibration ratings for
all instrumented sites to calculate discharge records.
- Begin correlation analyses to determine relations
between instrumented sites and all other non-instrumented sites, in order
to calculate individual flows across all bridges and culverts within the
records for WY-2006 to be made available at the USGS -SOFIA web address; April 2007.
