Simulations of water-level drawdowns in proposed well-field areas, Dade County, Florida Simulations of water-level drawdowns in proposed well-field areas, Dade County, Florida
Electrical analog model simulations of hydraulic conditions in the Biscayne aquifer were made at proposed inland well-field sites in Dade County, Florida. Simulated drawdowns of water levels after 7 months of continuous pumping at 50, 100, and 150 million gallons per day were obtained at each site. Simultaneous pumping of each of the sites at 50 million gallons per day showed that after...

Nitrogen and phosphorus uptake in the Everglades Conservation Areas, Florida, with special reference to the effects of backpumping runoff Nitrogen and phosphorus uptake in the Everglades Conservation Areas, Florida, with special reference to the effects of backpumping runoff
In much of the water pumped into the northern Everglades, Florida, concentrations of inorganic nitrogen and phosphorus are relatively high. These nutrients are transported in the canals or into the peripheral marshes. Concentrations decrease sharply within 330 feet or less of the canals, whereas specific conductance remains essentially unchanged within this distance. The sharp decrease...

Analog-model simulations for secondary canal controls and forward pumping water-management schemes in southeast Florida Analog-model simulations for secondary canal controls and forward pumping water-management schemes in southeast Florida
The analog model of the Biscayne aquifer of southeast Florida was used to approximate the effects of two proposed water-management schemes. One involved adding a secondary control structure in a major canal which is controlled near the coast. In the model the controls were operated in accordance with canal water level both above and below the secondary control. Although the model could...

Analysis of selected benthic communities in Florida Everglades with reference to their physical and chemical environment Analysis of selected benthic communities in Florida Everglades with reference to their physical and chemical environment
Species diversity and numbers of benthic macroinvertebrates were determined at 12 sites, both canals and marshes, in the Everglades of south Florida. The values calculated are used to indicate long-term trends in water quality and variations between study areas. Species diversity at all sites was generally in a range indicative of degraded water quality. The number of organisms per...

Hydraulic conductivity and water quality of the shallow aquifer, Palm Beach County, Florida Hydraulic conductivity and water quality of the shallow aquifer, Palm Beach County, Florida
Subsurface geophysical logs were correlated with logs of drill cuttings to determine the permeability of selected zones of the shallow aquifer, Palm Beach County, Fla. The hydraulic conductivity of the aquifer is estimated to range from 1 to 130 feet per day, based on lithology and physical properties. The yield of wells penetrating this aquifer ranges from 100 to more than 1,000 gallons...

Water resources data for South Carolina, water year 1975 Water resources data for South Carolina, water year 1975
Water resources data for the 1975 water year for South Carolina consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels in wells. This report contains discharge records for 56 gaging stations; stage only records for 4 gaging stations; stage and contents for 11 lakes and reservoirs; water quality for 19 gaging...
