Ground-water data on the Hudson River basin, New York
Deborah S. Hammond, Ralph C. Heath, Roger Milton Waller
1978, Open-File Report 78-710
Ground water in the Hudson River basin occurs in unconsolidated deposits and consolidated rock. Sand and gravel units of the unconsolidated deposits, which occur principally in valley bottoms, form the best aquifers and commonly provide well yields of several hundred gallons per minute. Carbonate aquifers are the most productive consolidated...
Water quality investigation of Francis Slocum Lake, Luzerne County, Pennsylvania
James L. Barker
1978, Open-File Report 78-819
This report summarizes water-quality data collected in the Francis Slocum Lake drainage basin, Pennsylvania, during an assessment from October 1976 to September 1977. Data were collected for nitrogen, phosphorus, carbon, and fecal coliform and fecal streptococcal bacteria.Results of the restricted sampling indicate that nutrient recycling within the lake is sufficient...
Impact of flow regulation and power plant effluents on the flow and temperature regimes of the Chattahoochee River - Atlanta to Whitesburg, Georgia
Robert E. Faye, Harvey E. Jobson, Larry F. Land
1978, Open-File Report 78-528
A calibrated and verified transient flow temperature model was used to evaluate the effects of flow regulation and powerplant loadings on the natural temperature regime of the Chattahoochee River in northeast Georgia. Estimates were made of both instantaneous and average natural temperatures in the river during an eight-day period in...
Definitions of components of the Water Data Sources Directory maintained by the National Water Data Exchange
William A. Knecht, Melvin D. Edwards
1978, Open-File Report 77-775
This report contains a definition and description of each component of the Water Data Souces Directory data base maintained by the National Water Data Exchange (NAWDEX). It is intended, primarily, to assist those persons using the Water Data Sources Directory in understanding information obtained from the data base. The Water...
Water resources along the TAPS route, Alaska, 1970-74
Joseph M. Childers, J. W. Nauman, D.R. Kernodle, P.F. Doyle
1978, Open-File Report 78-137
The U.S. Geological Survey installed 10 streamgaging and water-quality stations along the trans-Alaska pipeline route (TAPS) starting in 1970. These stations, mostly north of Fairbanks, add to the historical network of gaging stations and provide records of hydrologic conditions along the TAPS route. Selected data from 23 gaging stations along...
The hydrothermal system of Long Valley Caldera, California
M.L. Sorey, Robert Edward Lewis, F. H. Olmsted
1978, Professional Paper 1044-A
Long Valley caldera, an elliptical depression covering 450 km 2 on the eastern front of the Sierra Nevada in east-central California, contains a hot-water convection system with numerous hot springs and measured and estimated aquifer temperatures at depths of 180?C to 280?C. In this study we have synthesized the results...
Summary of U.S. Geological Survey investigations and hydrologic conditions in the Southwest Florida Water Management District for 1977
A. Buono, K.W. Causseaux, J.E. Moore
1978, Open-File Report 78-331
This report summarizes the activities of the Southwest Florida Subdistrict of the U.S. Geological Survey, Water Resources Division for fiscal year 1977. The organization and mission of the subdistrict office are described. The cooperative program for fiscal year 1977 included 41 interpretive investigations. Abstracts of twenty reports released by the...
Annual peak discharges from small drainage areas in Montana through September 1977
R. J. Omang, J. A. Hull
1978, Open-File Report 78-219
Annual peak stage and stream-discharge data have been collected and tabulated for crest-stage gaging sites in Montana. The crest-stage program was begun in July 1955 to investigate the magnitude and frequency of floods from small drainage areas. The program has expanded from 45 crest-stage gaging stations initially to 191 stations...
Unsteady streamflow simulation using a linear implicit finite-difference model
Larry F. Land
1978, Water-Resources Investigations Report 78-59
A computer program for simulating one-dimensional subcritical, gradually varied, unsteady flow in a stream has been developed and documented. Given upstream and downstream boundary conditions and channel geometry data, roughness coefficients, stage, and discharge can be calculated anywhere within the reach as a function of time.The program uses a linear...
EROS Data Center Landsat digital enhancement techniques and imagery availability
Wayne G. Rohde, Jinn Kai Lo, Russell A. Pohl
1978, Canadian Journal of Remote Sensing (4) 63-76
The US Geological Survey's EROS Data Center (EDC) is experimenting with the production of digitally enhanced Landsat imagery. Advanced digital image processing techniques are used to perform geometric and radiometric corrections and to perform contrast and edge enhancements. The enhanced image product is produced from digitally preprocessed Landsat computer compatible...
Use of a remote computer terminal during field checking of Landsat digital maps
Charles J. Robinove, C.F. Hutchinson
1978, Journal of Research of the U.S. Geological Survey (6) 511-514
Field checking of small-scale land classification maps made digitally from Landsat data is facilitated by use of a remote portable teletypewriter terminal linked by teleplume to the IDIMS (Interactive Digital Image Manipulation System) at the EDC (EROS Data Center), Sioux Falls, S. Dak. When field checking of maps 20 miles...
Hydrological applications of Landsat imagery used in the study of the 1973 Indus River flood, Pakistan
Morris Deutsch, F.H. Ruggles Jr.
1978, Journal of the American Water Resources Association (14) 261-274
During August and September 1973, the Indus River Valley of Pakistan experienced one of the largest floods on record, resulting in damages to homes, businesses, public works, and crops amounting to millions of rupees. Tremendous areas of lowlands were inundated along the Indus River and major tributaries. Landsat data made...
Manual on characteristics of Landsat computer-compatible tapes produced by the EROS Data Center digital image processing system
Patrick F. Holkenbrink (compiler)
1978, Report
Landsat data are received by National Aeronautics and Space Administration (NASA) tracking stations and converted into digital form on high-density tapes (HDTs) by the Image Processing Facility (IPF) at the Goddard Space Flight Center (GSFC), Greenbelt, Maryland. The HDTs are shipped to the EROS Data Center (EDC) where they are...
Water-resources setting, Martin County, Florida
R. Adam Miller
1978, Water-Resources Investigations Report 77-68
This report describes some basic principles of hydrology as they apply to Martin County, Florida. The major land features are described first, then the hydrologic cycle and surface-water and ground-water resource.
