Computer modeling of ground-water availability in the Pootatuck River Valley, Newtown, Connecticut
F.P. Haeni, Elinor H. Handman
1978, Water-Resources Investigations Report 78-77
A hydrologic analysis of the stratified drift in Newtown, Conn., based on available data, test drilling, seismic refraction profiling, and the stream-aquifer connection was performed using a digital computer model. Simulated pumping indicates that a total of 4.0 million gallons of water per day (Mgal/d) can be withdrawn from the...
Principal facts for a gravity survey of the Fly Ranch Extension Known Geothermal Resource Area, Pershing County, Nevada
Donald L. Peterson, Harold E. Kaufmann
1978, Open-File Report 78-107-C
During July 1977, forty-four gravity stations were obtained in the Fly Ranch Extension Known-Geothermal Resource Area and vicinity, northwestern Nevada. Elevations for three stations were estimated from lake bed topographic contours. Horizontal and vertical positions for stations FREX33 through FREX43 were determined from plane-table surveying. Positions for the remaining stations...
Water-quality indices for specific water uses
J.D. Stoner
1978, Circular 770
Water-quality indices were developed to assess waters for two specific uses--public water supply and irrigation. The assessment for a spcific water use is based on the availability f (of (1) a set of limits for each water quality property selected, (2) a rationale for selection, and (3) information that permits...
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...
Monthly fluctuations in the quality of ground water near the water table in Nassau and Suffolk Counties, Long Island, New York
Brian G. Katz, Stephen E. Ragone, Juli B. Lindner-Lunsford
1978, Water-Resources Investigations Report 78-41
Water samples from wells in a sewered and an unsewered suburban area and an unsewered rural area on Long Island, N.Y. were collected and analyzed monthly from August 1975 to July 1976 to determine the concentrations of chloride, sulfate, and nitrate in ground water near the water table. Short-term and...
Summary of water resources for the Campo, Cuyapaipe, La Posta, and Manzanita Indian Reservations and vicinity, San Diego County, California
W. R. Moyle, D.J. Downing
1978, Open-File Report 77-684
Since 1945, precipitation and runoff in California on the Campo, Cuyapaipe, La Posta, and Manzanita Indian Reservations and surrounding areas generally have been below normal, and ground-water levels are declining. Most of the water is of excellent quality. The analysis of water from one well on the Campo Reservation indicates...
Nitrogen, phosphorus, organic carbon, and biochemical oxygen demand: in Florida surface waters, 1972
Matthew I. Kaufman, J.E. Dysart
1978, Water-Resources Investigations Report 78-43
Water samples were collected during spring and autumn 1972 from about 100 surface-water sites in Florida. The samples were analyzed for the plant nutrients, nitrogen and phosphorus. In most waters, nitrogen concentrations are less than 2.0 milligrams per liter as nitrogen, and organic nitrogen is dominant. Median total nitrogen concentration...
Reconnaissance assessment of erosion and sedimentation in the Canada de los Alamos Basin, Los Angeles and Ventura counties, California
J. M. Knott
1978, Open-File Report 78-873
An assessment of present erosion and sedimentation conditions in the Canada de Los Alamos basin, Calif., was made to aid in estimating the impact of off-road-vehicle use on the sediment yield of the basin. Evaluations were made by reconnaissance techniques and by comparing the study area with other off-road-vehicle sites...
