Water Flows and Nutrient Loads to the Southwest Coast of Everglades National Park, FloridaEntry ID: USGS_SOFIA_metval
Abstract: n 1996, the U.S. Geological Survey began a 4-year study of the flow and nutrient characteristics of three major streams that drain parts of the Everglades National Park. An upward looking acoustic Doppler current profiler, a water-level sensor, and two specific conductance sensors were installed at each site. Monthly discharge measurements are made with an acoustic Doppler current profiler to ... develop discharge ratings. Nutrient data are collected monthly at each site.
Data collected at the Broad River, Harney River, and Shark River stations include water level, water velocity, specific conductance and temperature, total and dissolved phosphorus species, pH, and dissolved oxygen. These three stations were established in 1997 and two additional stations (Lostmans Creek and North River) were established in 1999. These stations are also equipped with wind speed and direction sensors and barometric pressure sensors to correlate with water level and stream discharge.
The southwest coast of Florida is part of a wilderness area with unique hydraulic characteristics that has historically been described as the "River of Grass". Flat terrain and lack of controlled topographic information has made it difficult to define drainage divides. Low gradients, coupled with tidal effects, create complex conditions under which to measure river flow. It has been almost thirty years since any effort has been made to monitor flow characteristics continuously in the area. Significant technological advancements have occurred during this time and this new technology can be applied to help obtain the information needed to make informed decisions about the future of this unique coastal area.
Flow, nutrient concentrations, and nutrient load data will provide part of the basic information needed to understand the hydrologic and water-quality characteristics for a part of the southwest coast of Florida. The analysis of these measurements will help characterize the current conditions for the three sites and explain the relation between upgradient water levels and southwest coastal stream flows, and the possible interaction between southwest coastal waters and the waters of Florida Bay. The data can also be used as input to hydrodynamic and water-quality models.
This project is now part of the Tides and Inflows in the Mangrove Ecotone (TIME) Model Development project.
