Availability and chemical quality of water from surficial aquifers in Southwest Minnesota
D. G. Adolphson
1983, Water-Resources Investigations Report 83-4030
The principal surficial aquifers in southwest Minnesota consist of outwash and alluvium material deposited in river valleys. The largest and most productive of these aquifers occupy the valleys of the Cottonwood, Des Moines, Redwood, and Rock Rivers and of tributaries to the Big Sioux River. Minor aquifers, adequate only for...
Drainage areas of selected sites on streams in North Carolina
Robert L. Meikle
1983, Open-File Report 83-211
For the past several years, drainage-area data have been determined for approximately 12,400 selected sites on streams in North Carolina. Location information, including distance of nearby towns or other landmarks, latitude and longitude coordinates, county in which the site lies, and the name of the latest topographic maps on which...
Long-range plans for hydrologic investigations in New Mexico
H. L. Case III, G. E. Welder
1983, Open-File Report 83-696
Objectives of the hydrologic-data-collection projects presented in this report include continuing to identify future data needs; conducting an analysis of the water-quality, ground-water, and surface-water observation networks; and entering all available current and historical hydrologic data into the U.S. Geological Survey Water Data Storage and Retrieval System (WATSTORE). Objectives of...
Report of reprocessing of reflection seismic profile X-5 Waste Isolation Pilot Plant site, Eddy County, New Mexico
John J. Miller
1983, Open-File Report 83-316
Seismic reflection profile X-5 exhibits a 7,700 ft long anomalous zone of poor quality to nonexistent reflections between shotpoints 100 and 170, compared to the high-quality, flat-lying, coherent reflections on either side. Results from drill holes in the area suggest 'layer cake' geology with no detectable abnormalities such as faults...
Reservoir-development impacts on surface-water quantity and quality in the Yampa River basin, Colorado and Wyoming
D. Briane Adams, Daniel P. Bauer, Robert H. Dale, Timothy Doak Steele
1983, Water-Resources Investigations Report 81-30
Development of coal resources and associated economy is accelerating in the Yampa River basin in northwestern Colorado and south-central Wyoming. Increased use of the water resources of the area will have a direct impact on their quantity and quality. As part of 18 surface-water projects, 35 reservoirs have been proposed...
Fortran computer programs to plot and process aquifer pressure and temperature data
J.B. Czarnecki
1983, Water-Resources Investigations Report 83-4051
Two FORTRAN computer programs have been written to process water-well temperature and pressure data recorded automatically by a datalogger on magnetic tape. These programs process the data into tabular and graphical form. Both programs are presented with documentation. Sample plots of temperature versus time, water levels versus time, aquifer pressure...
Hydrologic data for the Great and Denbow heaths in eastern Maine, October 1981 through October 1982
Wallace J. Nichols
1983, Open-File Report 83-865
Hydrologic data collected on the Great and Denbow Heaths, Maine, include precipitation, pan evaporation, air temperatures, streamflow, and ground water levels. These data were collected for a peat bog hydrology study conducted in cooperation with the Maine Geological Survey. The data network consisted of climate information from three rain gages,...
Hydrologic data for the Great and Denbow heaths in eastern Maine, October 1980 through September 1981
Wallace J. Nichols, J.A. Smath, J.T. Adamik
1983, Open-File Report 83-866
Hydrologic data collected on the Great and Denbow Heaths, Maine, include precipitation, pan evaporation, air temperatures, streamflow, groundwater levels, and water quality constituents. These data were collected for a peat bog hydrology study conducted in cooperation with the Maine Geological Survey. The data network consisted of climate information from three...
Subsurface storage of freshwater in South Florida; a digital analysis of recoverability
Michael L. Merritt
1983, Open-File Report 83-536
As part of a feasibility study of cyclic freshwater injection, digital models were implemented to analyze the relation of recovery efficiency to various hydrogeologic conditions which could prevail in brackish aquifers and to various management regimes. The analyses implemented an approach in which the control for sensitivity testing was a...
AIRYROOT: A Fortran program for calculating the gravitational attraction of an Airy isostatic root out to 166.7 km
R.W. Simpson, R.C. Jachens, R.J. Blakely
1983, Open-File Report 83-883
This report describes a FORTRAN-77 program called AIRYROOT which calculates the gravitational attraction at sea level of an Airy isostatic root extending out to a radius of 166.7 km. The program incorporates an efficient algorithm devised by Parker (1912) which uses the fast Fourier transform to calculate potential field anomalies....
Hydraulic considerations in sampling the unsaturated zone with inclined gravity lysimeters
E. T. Oaksford
1983, Water-Resources Investigations Report 83-4005
Inclined gravity lysimeters as deep as 5.39 meters below land surface designed for sampling soil water in coarse sand under continuous ponding conditions, were shown to be capable of collecting 10 liters per hour at an infiltration rate of 0.5 meter per hour. This represents a capture efficiency of approximately...
Preliminary map of limonitic hydrothermal alteration for portions of the Needles 1° x 2° quadrangle, Arizona and California
Gary L. Raines
1983, Open-File Report 83-421
Portions of the Needles quadrangle have been designated by the Bureau of Land Management as potential wilderness areas and are being evaluated by a multidisciplinary team to determine the mineral-resource potential. As a part of this study Landsat images are being used to map the generalized distribution of limonitic materials...
Streamflow and suspended-sediment transport in Garvin Brook, Winona County, southeastern Minnesota: Hydrologic data for 1982
G. A. Payne
1983, Open-File Report 83-212
Streamflow and suspended-sediment-transport data were collected in Garvin Brook watershed in Winona County, southeastern Minnesota, during 1982. The data collection was part of a study to determine the effectiveness of agricultural best-management practices designed to improve rural water quality. The study is part of a Rural Clean Water Program demonstration...
Water quality at and adjacent to the south Dade County solid-waste disposal facility, Florida
D.J. McKenzie
1983, Water-Resources Investigations Report 83-4003
A water-quality reconnaissance was conducted at the south Dade County solid-waste landfill near Goulds, Florida, from December 1977 through August 1978. The landfill is located directly on the unconfined Biscayne aquifer, which, in the study area, is affected by saltwater intrusion. Water samples collected from six monitor well sites at...
