Geologic evaluation of waste-storage potential in selected segments of the Mesozoic aquifer system below the zone of fresh water, Atlantic Coastal Plain, North Carolina through New Jersey
Philip M. Brown, M.S. Reid
1976, Professional Paper 881
This report describes the distribution of subsurface environments in the Atlantic Coastal Plain?North Carolina through New Jersey, that are seen to have geologic potential for the storage of toxic waste. The environments described consist of layers of sand or sandstone, 20 feet or more in thickness, that are immediately overlain...

Hydrologic studies of the U.S. Geological Survey related to coal development on Colorado
Water Resources Division, U.S. Geological Survey
1976, Open-File Report 76-549
This report summarizes the hydrologic studies related to coal development being conducted by the U.S. Geological Survey in the State of Colorado. The objective of the hydrologic data-acquisition program is to collect surface-water quality and quantity data and ground-water level records. These data are needed to define predevelopment conditions and...
Machine-assisted analysis of Landsat data in the study of crop-soils relationships
William C. Draeger
1976, Open-File Report 76-603
To date, relatively few studies have dealt with crop-soil interactions as they affect the appearance of agricultural areas on Landsat imagery, and hence crop and soil classification or the analysis of agricultural land use.The Image 100, a computer-based data analysis system which allows an interpreter to interact directly and rapidly with Landsat computer...
Project development and data programs for assessing the quality of the Willamette River, Oregon
David A. Rickert, Walter G. Hines, Stuart W. McKenzie
1976, Circular 715-C
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
Aerial profiling of terrain to define stream-valley geometry: study report
Mukund Desai, William A. Drohan, John W. Hursh, Glenn Mamon, Douglas G. Youmans
1976, Open-File Report 76-672
A six-month engineering analysis was performed by The Charles Stark Draper Laboratory, Inc., at the request of the U. S. Geological Survey, to investigate the suitability of an airborne instrument package based on inertial techniques to serve as the datum for a laser altimeter in a system for aerial profiling...
Floods of March-April 1973 in southeastern United States
George W. Edelen Jr., John Frederick Miller
1976, Professional Paper 998
Floods during March-April 1973 were the greatest of record on many streams in nine major river basins in seven Southeastern States. The major thrust of the flood extended throughout the central part of the Tennessee River basin and into adjacent basins. Recurrence intervals of peak discharges exceeded 100 years at...
Chemical composition data and calculated aquifer temperature for selected wells and springs of Honey Lake Valley, California
Robert H. Mariner, T. S. Presser, William C. Evans
1976, Open-File Report 76-783
Major element, minor element, and gas composition data are tabulated for 15 springs and wells in Honey Lake Valley, California. Wendel and Amedee hot springs issue Na-S04-C1 waters at boiling or near boiling temperatures; the remaining springs and wells issue Na-HC03 waters at temperatures ranging from 14 to 33 deg...
Flood-frequency analysis for small natural streams in Georgia
Harold G. Golden, McGlone Price
1976, Open-File Report 76-511
Flood information from 104 project basins (0.1 to 20 square miles) and data available from 170 larger basins (20 to 1,500 square miles) are analyzed to provide planners and designers with relations for estimating the magnitude and frequency of flood-peak discharges on small natural streams in Georgia. More than 90...
Hydrologic interpretation of geophysical data from the southeastern Hueco Bolson, El Paso, and Hudspeth Counties, Texas
Joseph Spencer Gates, W. D. Stanley
1976, Open-File Report 76-650
Airborne-electromagnetic and earth-resistivity surveys were used to explore for fresh ground water in the Hueco Bolson southeast of El Paso, Texas. Aerial surveys were made along about 500 miles (800 km) of flight line, and 67 resistivity soundings were made along 110 miles (180 km) of profile. The surveys did...
Shallow sedimentary framework of Georges Bank
R. S. Lewis, R. E. Sylwester
1976, Open-File Report 76-874
Two thousand nine hundred kilometers of minisparker data were collected on Georges Bank by the United States Geological Survey during October of 1975. Several sedimentary features have been observed in the data, The bank is recognized as a compound feature resulting from erosion of Tertiary coastal-plain strata followed by deposition...
Lithium in sediments and rocks in Nevada
Robert G. Bohannon, Allen L. Meier
1976, Open-File Report 76-567
Reconnaissance geochemical sampling has been conducted by the Lithium Resource Program of the United States Geological Survey for much of the Western U.S. Sediment, rock, and brine samples have been collected in many states, but this report describes just those solid samples collected in Nevada. Further reports by other members...
Water-resources data collected in the Devils Hole area, Ash Meadows, Nevada, 1975-76
