1978, Water-Resources Investigations Report 78-5
A technique is presented for estimating the magnitude and frequency of floods in Virginia. For 299 gaged sites, the magnitudes of floods having recurrence intervals of 2 to 100 years are provided in tables. For ungaged sites, regression relations are presented that allow the estimation of flood magnitudes based on...
Model evaluation of the hydrogeology of the Cypress Creek well field in west-central Florida

1978, Water-Resources Investigations Report 78-79
The Cypress Creek well field is being developed to help supply a rapidly growing population in west-central Florida. The ground-water system in the Cypress Creek well-field area consists of a surficial sand aquifer, a semiconfining clay layer ranging from 2 to 25 feet in thickness, and a sequence of carbonate...
Potentiometric surface of Floridan aquifer, Southwest Florida Water Management District and adjacent areas, September 1977
P.D. Ryder, L. R. Mills, C. P. Laughlin
1978, Water-Resources Investigations Report 78-9
A potentiometric-surface map of the Southwest Florida Water Management District depicts the annual high water-level period. Potentiometric levels increased 15 to 30 feet between May 1977 and September 1977 in the citrus and farming sections of southeastern Hillsborough, northern Hardee, and southwestern Polk Counties. These areas are widely affected by...
Subsurface geology and paleogeography of Queens County, Long Island, New York
Julian Soren
1978, Water-Resources Investigations Report 77-34
Unconsolidated strata of clay, silt, sand, and gravel of Late Cretaceous and pre-Wisconsin Pleistocene ages lie between crystalline basement rocks (bedrock) of Precambrian ( ) age and unconsolidated deposits of late Pleistocene (Wisconsin) and Holocene ages in Queens County, Lond Island, N.Y. Data collected during a recent study of the...
Flood profiles for Peace River, south-central Florida
W. R. Murphy Jr., K.M. Hammett, C. V. Reeter
1978, Water-Resources Investigations Report 78-57
This report presents flood heights and profiles for a 70-mile reach of Peace River from Bartow to Arcadia, Fla. The flood heights were calculated using the U.S. Geological Survey step-backwater model. Profiles were prepared for floods having expected recurrence intervals of 2, 2.33, 5, 10, 25, 50, 100, 200, and...
Flood profiles for lower Brooker Creek, west-central Florida
W.R. Murphy
1978, Water-Resources Investigations Report 77-115
Flood heights are computed for a range of recurrence intervals for a 12.6 mile reach of Brooker Creek, beginning at the mouth at Lake Tarpon. A Geological Survey step-backwater computer program, E431, was used in these analyses using: (1) Stream and valley cross-section geometry and roughness data; (2) Recurrence interval...
Geohydrologic data from the Jemez Mountains and vicinity, north-central New Mexico
Frank W. Trainer
1978, Water-Resources Investigations Report 77-131
The Jemez Mountains volcanic region, on the west margin of the Rio Grande rift in north-central New Mexico, is the site of studies for power development from geothermal heat. This report summarizes geohydrologic data to provide background information relative to the geothermal exploration and to investigate the usefulness of hydrology...
Water-table map of Walworth County, Wisconsin
Marvin G. Sherrill, John R. Erickson
1978, Water-Resources Investigations Report 79-42
A map of the water table in Walworth County in southeastern Wisconsin was prepared using water levels from nearly 600 wells. The work was done as a cooperative project between the U.S. Geological Survey, the University of Wisconsin-Extension, Geological and Natural History Survey, and the Southeastern Wisconsin Regional Planning Commission....
Preliminary hydrologic budget of the sand-and-gravel aquifer under unstressed conditions: with a section on water-quality monitoring, Pensacola, Florida
Henry Trapp Jr.
1978, Water-Resources Investigations Report 77-96
The sand-and-gravel aquifer is the only freshwater aquifer in southern Escambia County, Fla. Problems related to the development of the aquifer include sustained yield, contamination, and saltwater intrusion. A digital model was applied to the sand-and-gravel aquifer in central and southern Escambia County treating the aquifer 's 'main producing zone...

Method of estimating natural recharge to the Edwards Aquifer in the San Antonio area, Texas
Celso Puente
1978, Water-Resources Investigations Report 78-10
The method of estimating annual recharge is based on data collected from a network of stream-gaging stations and on assumptions related to applying the runoff characteristics from gaged areas to ungaged areas. The basic approach is a water-balance equation, in which recharge within a stream basin is the difference between...
