Water resources of Okaloosa County and adjacent areas, Florida
Henry Trapp, C.A. Pascale, J.B. Foster
1977, Water-Resources Investigations Report 77-9
Okaloosa County, in the northwest Florida panhandle, uses the Floridan aquifer for water supply, although it also has abundant surface water and ground water in the surficial sand-and-gravel aquifer. Water levels have declined locally more than 90 feet in the upper limestone of the Floridan aquifer. The Floridan aquifer is...
Ground-water resources along the Blue Ridge Parkway, North Carolina
M. D. Winner Jr.
1977, Water-Resources Investigations Report 77-65
The best areas to develop ground water along the Blue Ridge Parkway in North Carolina are in broad draws and in stream valleys where draws open to the valleys. Saprolite thickness in these places can exceed 50 feet and provide adequate ground-water storage; draws are topographic expressions of fracture zones...
Techniques for estimating flood discharges for Oklahoma streams; Techniques for calculating magnitude and frequency of floods in Oklahoma from rural and urban areas under 2500 square miles, with compilations of flood data through 1975
Wilbert O. Thomas Jr., Robert K. Corley
1977, Water-Resources Investigations Report 77-54
Statewide regression equations are defined for estimating peak discharges of floods having recurrence intervals ranging from 2 to 500 years. Contributing drainage area, main-channel slope and mean annual precipitation are the independent variables required for estimating flood discharges for rural streams. For urban streams the percentage of the basin that...
Radioelement concentrations and preliminary radiometric ages of rocks of the Kigluaik Mountains, Seward Peninsula, Alaska
Carl Maurice Bunker, Carl E. Hedge, C.L. Sainsbury
1977, Open-File Report 77-735
A sequence of old metamorphic rocks including the Kigluaik and Nome Groups is exposed in the Kigluaik Mountains of the Seward Peninsula. The high-grade metasedimentary rocks give a whole-rock Rb-Sr age of 735 m.y. This late Precambrian age is believed to be the time of metamorphism. Orthogneisses, intrusive into the...
Saltwater intrusion in the shallow aquifer in Martin and Palm Beach counties, Florida
W. B. Scott, L. F. Land, H.G. Rodis
1977, Water-Resources Investigations Report 76-135
Urban growth has been rapid in recent years in Palm Beach and Martin Counties, Fla. The withdrawal of large quantities of fresh ground water in the vicinity of the coast has reduced or locally reversed the natural seaward hydraulic gradient and, in places, allowed saltwater to advance landward in the...
Experimental study of artificial recharge alternatives in northwest Hillsborough County, Florida
William C. Sinclair
1977, Water-Resources Investigations Report 77-13
Extensive water withdrawal from the Floridan aquifer in the urban Tampa Bay area has induced leakage from the overlying surficial aquifer adversely effecting the water table and lake levels. Artificial recharge could reduce the impact of these effects. Four experiments were conducted to investigate possible recharge alternatives; sinkhole recharge, water-spreading,...
The Cockfield aquifer in Mississippi
C. A. Spiers
1977, Water-Resources Investigations Report 77-17
The Cockfield Formation in the upper part of the Claiborne Group of Eocene age is a principal source of water supplies in Mississippi. The Cockfield Formation consists of beds of fine to medium sand, sandy carbonaceous clay, and thin beds of lignite. The largest withdrawal from the aquifer is in...
