Description:

Abstract:

The data sets contain values collected at 15 minute intervals for stage (water level), discharge (flow), salinity, and temperature between 1996 and 2000. The stage is measured in feet, the discharge in cubic feet per second (cfs), and salinity in parts per million (ppm)

Purpose:

Two of the many unknowns along the northeastern coast of Florida Bay have been the amount of freshwater flowing into the bay from the mainland and the effect that years of man-made changes in water deliveries have had, and will have, in the quality of the bay environment. Flow and salinity information along the mangrove zone is provided through this data to study the extent of the effects that water management practices on the mainland have on the quality of the Florida Bay environment. Hydrodynamic modelers of the Everglades (mainland) and Florida Bay will use these data to calibrate and to verify models describing flow through the mangrove zone, and circulation patterns within the bay. The main objectives of the project which generated these data are to determine water discharge along the northeastern coast of Florida Bay, to study the flows and salinity distribution patterns of shallow streams within the study area, and to provide hydrodynamic models with boundary and calibration information at selected locations along the mangrove zone.

Process_Description:

Prior to the development of currently available acoustic instruments, it was very difficult to gage flows in streams discharging into Florida Bay. Standard methods for field data collection and flow computations are impractical and inaccurate because of the low velocities, flow reversal, and bi-directional flow in which high-salinity water flows inland under freshwater flowing out to the bay. With today's state-of-the art acoustic instrumentation, such as the Acoustic Velocity Meter (AVM) and the Acoustic Doppler Current Profiler (ADCP), it is possible to accurately gage flows in this environment because of the ability of these instruments to quickly measure low or rapidly changing water velocities, even during stratified or bi-directional flow. AVM systems have proven to be accurate instruments in the measurement of water velocities along a horizontal plane across stream and can be permanently installed to collect continuous velocity data that, along with water-level data, are used to produce continuous records of discharge.

ADCP instruments are used to measure water velocities in three dimensions. These measurements are then used to calculate the total flow through a stream section at a given time. The ADCP uses the Doppler shift from four acoustic beams sent downward in set angles to measure the velocity of water, depth, and distance traveled across the stream transect. Field measurements made with the ADCP's are used to develop relations between AVM velocities and discharge at gaged sites.

With the assistance of Everglades National Park, discharge measurements were made with ADCP's near the mouths of the major streams flowing into Florida Bay. Results of these measurements verified the applicability of ADCP's for discharge measurements under these environmental conditions, provided data on high flows into the bay, and helped in the understanding of flow patterns for each of the measured streams.

Selected streams flowing into Florida Bay were instrumented with AVM's and temperature and specific conductance sensors in order to measure most of the total freshwater flow from the mainland into the bay. Sites are located along the mainland coast of east Florida Bay and represent most of the freshwater flowing south into the bay from Taylor Slough and the C-111 Canal basins. Three of these sites (Trout Creek Canal station and two C-111 Canal stations) are instrumented and maintained by Everglades National Park. Monthly ADCP discharge measurements were collected for rating AVM systems, and monthly collection of water samples were collected for total nutrient analysis.

This work was coordinated with activities from other agencies and institutions who need simultaneous flow data during biological or chemical samplings.

Sites that can be discontinued without sacrificing the quality nor the spatial coverage of flow information within the study area will be determined.
