The Floridan aquifer system is one of the major sources of groundwater supplies in the United States. This productive aquifer system underlies all of Florida, southeast Georgia, and small parts of adjoining Alabama and South Carolina, for a total area of about 100,000 square miles. About 3 billion gallons of water per day were withdrawn from the aquifer system in 1980, and in many areas...

The surficial aquifer system, in which an unconfined groundwater flow system exists, comprises the sediments from land surface to the intermediate confining unit (formerly called the Floridan aquiclude) in Broward County, Florida. These sediments have hydraulic conductivities that range more than seven orders of magnitude from about 0.001 ft/d to more than 10,000 ft/d. The sediments are...

A study was conducted to determine the low-flow frequency of freshwater flow in the Atlantic Intracoastal Waterway (AICW) near Myrtle Beach, South Carolina and to determine the effects of proposed freshwater withdrawals of 45 cu ft/sec at the location of the saltwater-freshwater interface. Discharges simulated in the AICW for 1982-86 using BRANCH one-dimensional flow model were used to...

The surface-water quality in the Cedar River basin was evaluated by analyzing the occurrence, distribution, and transport of common inorganic constituents and selected trace inorganic and organic constituents, with emphasis on herbicides. The surface-water quality of the Cedar River basin was monitored from May 1984 through November 1985. Depth integrated surface-water samples generally...

As of January 1, 1988, the surface-water data-collection network in Texas included 368 continuous streamflow, 12 continuous or daily reservoir-content, 38 gage height, 15 crest-stage partia 1-record, 4 periodic discharge through range, 32 floodhydrocjraph partial-record, 9 flood-profile partial-record, 36 low-flow partial-record 45 daily chemical-quality, 19 continuous-recording water...

The U.S. results of a joint U.S.-U.S.S.R. expedition to the Bering Sea in 1984 investigated the chemical and biological interactions in the south, east, north and west regions. The nutrients, phytoplankton biomass and primary productivity were enhanced near the ends of a north-south transect of stations. The southern end of the transect had characteristics of the North Pacific Ocean with...

Information of fuelwood consumption and the local production of wood was collected in two small rural communities in Swaziland. Fuelwood consumption was estimated to be 0.77 t persona??1 yeara??1 in one community (Sigombeni), and 0.63 t persona??1 in the other (Bhekinkhosi). Bhekinkhosi was found to be experiencing a significant fuelwood production/consumption deficit and it expected...
