Triaxial and consolidation testing of cores from the 1976 Atlantic Margin Coring Project of the United States Geological Survey
Paul G. Swanson, Ralph E. Brown
1977, Open-File Report 78-124
This report contains the results of triaxial and consolidation-compression testing on selected cores taken by the Atlantic Margin Coring Project, a 60-day expedition to obtain core samples by drilling beneath the Continental Shelf and Slope of the eastern United States. The coring took place in July, August and September, 1976...
Hydrologic changes after logging in two small Oregon coastal watersheds
David Dell Harris
1977, Water Supply Paper 2037
Effects of clearcut, cable logging on the hydrologic characteristics of a small coastal stream in Oregon indicate an average 181-percent increase in sediment yield over a 7-year postlogging period. Annual runoff and high-flow volumes increased 19 and 1.1 inches (480 and 28 mm), respectively, after logging in the watershed. Clearcutting...
Maximum floodflows in the conterminous United States
John R. Crippen, Conrad D. Bue
1977, Water Supply Paper 1887
Peak floodflows from thousands of observation sites within the conterminous United States were studied to provide a guide for estimating potential maximum floodflows. Data were selected from 883 sites with drainage areas of less than 10,000 square miles (25,900 square kilometers) and were grouped into regional sets. Outstanding floods for...
Ground-water levels in the United States, 1972-74, north-central states
Water Resources Division, U.S. Geological Survey
1977, Water Supply Paper 2163
Publication of ground-water level data for the United States in water-supply papers was begun by the Geological Survey in 1935. From 1935 through 1939, a single water-supply paper for each year covering the entire nation was issued (Water-Supply Papers 777, 817, 840, 845, and 886). Since then water-supply papers have...
Relation of bulk precipitation and evapotranspiration to water quality and water resources, St. Thomas, Virgin Islands
Donald George Jordan, Donald W. Fisher
1977, Water Supply Paper 1663-I
St. Thomas, Virgin Islands, lies in what can be considered a true maritime regime, being 600 miles (1000 kilometers) from the nearest continental landmass. The island is composed almost entirely of volcanic rocks mantled by a thin soil seldom more than 2 feet (60 centimeters) thick. Rainfall, averaging about 40...
Ground-water resources of Cambodia
William Charles Rasmussen, Gary M. Bradford
1977, Water Supply Paper 1608-P
Cambodia (now the Khmer Republic), in tropical, humid southeast Asia, has an area of 175,630 km and a population of about 5 million. The Mekong River, one of the world's largest rivers, flows through Cambodia. Also, the Tonle Sap (Grand Lac), a highly productive fresh-water lake, functions as a huge...
Current oil and gas production from North American Upper Cretaceous chalks
Peter A. Scholle
1977, Circular 767
Production of oil and natural gas from North American chalks has increased significantly during the past five years, spurred by the prolific production from North Sea chalks, as well as by higher prices and improved production technology. Chalk reservoirs have been discovered in the Gulf Coast in the Austin Group,...
Environmental geology, Allegheny County and vicinity, Pennsylvania: Description of a program and its results
Reginald Peter Briggs
1977, Circular 747
Past land-use practices, including mining, in Allegheny County, Pa., have resulted in three principal environmental problems, exclusive of air and water contamination. They are flooding, landsliding, and subsidence over underground mines. In 1973, information was most complete relative to flooding and least complete relative to landsliding. Accordingly, in July 1973,...
The Alaskan Mineral Resource Assessment Program; background information to accompany folio of geologic and mineral resource maps of the McCarthy Quadrangle, Alaska
E. M. MacKevett, N. R. D. Albert, D.F. Barnes, J. E. Case, Keith Robinson, D.A. Singer
1977, Circular 739
The McCarthy 1? by 3? quadrangle, in eastern south-central Alaska, contains potentially significant resources of copper and possibly of a few other commodities. This circular and a companion folio of maps represent results of integrated field and laboratory studies in the disciplines of geology, geophysics, geochemistry, and satellite imagery that...
Short papers of the U.S. Geological Survey Uranium-Thorium Symposium, 1977
John A. Campbell, editor(s)
1977, Circular 753
This circular contains expanded abstracts for the technical papers presented at the 1977 Uranium and Thorium Research and Resources Conference, sponsored by the Branch of Uranium and Thorium Resources, U.S. Geological Survey. This Conference was held April 27 and 28, 1977, at the Colorado School of Mines, Golden. This was...
Algal conditions and the potential for future algal problems in the Willamette River, Oregon
David A. Rickert, R.R. Petersen, S. W. McKenzie, W. G. Hines, S.A. Wille
1977, Circular 715-G
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...
