Quality of rivers of the United States, 1975 water year; based on the National Stream Quality Accounting Network (NASQAN)
John C. Briggs, John F. Ficke
1977, Open-File Report 78-200
The National Stream Quality Accounting Network (NASQAN) was established by the U.S. Geological Survey to provide a nationally uniform basis for continuously assessing the quality of U.S. rivers. Stations generally are at the downstream end of hydrologic accounting units in order to measure the quantity and quality of water flowing...
Sub-sea temperatures and a simple tentative model for offshore permafrost at Prudhoe Bay, Alaska
Arthur H. Lachenbruch, B. Vaughn Marshall
1977, Open-File Report 77-395
In this report, we present temperatures measured in three holes drilled into the sea bed in the Prudhoe Bay region and a tentative interpretation of them in terms of the gross thermal regime and shoreline history of the area. The new holes (PB-1, PB-2, and PB-3, Figure 1) were drilled...

L.R. Peterson, Gerald Meyer
1977, Open-File Report 77-596
Initial moderate water requirements of the new Federal Capital Territory in Central Nigeria are available from the two large rivers, the Niger and Benue, from the smaller Gurara River, and possibly from several smaller streams. Ground water in the southwestern part of the Territory and in adjacent areas along the...
Analog-model analysis of regional three-dimensional flow in the ground-water reservoir of Long Island, New York
Rufus T. Getzen
1977, Professional Paper 982
A three-dimensional analog model of the ground-water system beneath Long Island, N.Y., provides a practical means for studying anisotropic flow on a regional scale. Constructional and operational techniques influence the simulation almost as much as model design does. Usefulness and accuracy of the model depend on (1) inherent and practical...
Theoretical drawdown due to simulated pumpage from the Ohio River alluvial aquifer near Siloam, Kentucky
J. M. Kernodle
1977, Water-Resources Investigations Report 77-24
Theoretical drawdown due to simulated pumpage was determined for a site near Siloam, Kentucky by using a digital ground-water-flow model. The maximum sustained yield of water from the single well was shown to be less than 900 gallons per minute, and, for a simulated pumping rate of 450 gallons per...

C.C. Daniel
1977, Water-Resources Investigations Report 77-63
A one-dimensional deterministic flow model based on the continuity equation had been developed to provide estimates of daily flow past a number of points on the Chowan River estuary of northeast North Carolina. The digital model, programmed in Fortran IV, computes daily average discharge for nine sites; four of these...
Water resources of the Maunabo Valley, Puerto Rico
D. G. Adolphson, M.A. Seijo, Tully M. Robison
1977, Water-Resources Investigations Report 76-115
The Maunabo Valley, in southestern Puerto Rico, consists of a 3.5-square-mile alluvial plain surrounded by hills of metavolcanic and igneous intrusive rocks. The principal source of ground water in the basin is a shallow unconfined aquifer in the valley alluvium. Continuous pumping of the shallow aquifer has induced the flow...
Hydrologic evaluation of the Arikaree Formation near Lusk, Niobrara and Goshen counties, Wyoming

The Arikaree Formation of early Miocene age is an aquifer of large areal extent and is composed of very fine grained, poorly bedded, loosely to moderately cemented sandstone and interbedded silt, limestone, and many concretionary layers. The area studied is about 800 square miles in southern Niobrara and northern Goshen...
Digital computer simulation model of the Englishtown aquifer in the northern coastal plain of New Jersey
W. D. Nichols
1977, Water-Resources Investigations Report 77-73
Continued decline of water levels in the Englishtown aquifer, in New Jersey, has caused considerable concern regarding the ability of the aquifer to meet future yield demands.

Geology and ground-water in western Santa Cruz County, California, with particular emphasis on the Santa Margarita Sandstone
J. P. Akers, L.E. Jackson
1977, Water-Resources Investigations Report 77-15
The water-bearing potential of the geologic formations in the western part of Santa Cruz County, Calif., is evaluated. Most of the sedimentary formations in this area are fine-grained rocks of Tertiary age that have been folded and faulted. These rocks, in general, yield supplies of water sufficient only for individual...

Ground water in the Lajas Valley, Puerto Rico
Henry R. Anderson
1977, Water-Resources Investigations Report 76-68
Lajas Valley is plagued with salinity and waterlogging problems of the soils. Use of brackish (500 milligrams per liter) ground water for irrigation compounded the problem until an irrigation-drainage system was constructed in 1955. Lajas Valley is an alluvium-filled trough between volcanic and limestone highlands. The alluvium, mostly clay and...

A brief investigation of the surface-water hydrology of Yemen Arab Republic
Henry Chiles Riggs
1977, Open-File Report 77-150
Yemen, near the southwest tip of the Arabian Peninsula, is a mountainous country bordered by a desert on the east and a coastal plain on the west. Rainfall is low and seasonal; consequently, most streams (wadis) are ephemeral. The natural flow regimens of many of the smaller wadis are modified...

Frequency response of the USGS short period telemetered seismic system and its suitability for network studies of local earthquakes
Jerry P. Eaton
1977, Open-File Report 77-844
The USGS telemetered seismic system was intended primarily to record small to moderate earthquakes (magnitude 0 to 4) at distances of a few km to several hundred km. Its frequency response is such that the recorded background noise at a moderately quite Coast Range site has a relatively flat 'record'...
