Depth estimation for ordinary high water of streams in the Mobile District of the U.S. Army Corps of Engineers, Alabama and adjacent states
Joe R. Harkins, Mark E. Green
1981, Open-File Report 81-481
Drainage areas for about 1,600 surface-water sites on streams and lakes in Florida are contained in this report. The sites are generally either U.S. Geological Survey gaging stations or the mouths of gaged streas. Each site is identified by latitude and longitude, by the general stream type, and by the...
Potentially favorable areas for large-yield wells in the Red River Formation and Madison Limestone in parts of Montana, North Dakota, South Dakota, Wyoming, and Nebraska
L.M. MacCary, E. M. Cushing, David L. Brown
1981, Open-File Report 81-220
The need for large quantities of energy has created interest in the Fort Union coal region of the Northern Great Plains. Extensive development of this coal, which may include onsite steam-power generation, gasification, liquefaction, and slurry-pipeline transport of the coal from this region, would place a heavy demand on the...
Gulf of Mexico summary report 2, August 1981: A revision of Outer Continental Shelf oil and gas activities in the Gulf of Mexico and their onshore impacts: A summary report, September 1980
Kenneth J. Havran
1981, Open-File Report 81-620
The Gulf of Mexico Outer Continental Shelf (OCS) continues to be the most intensively developed offshore oil- and gas-producing region in the world. With the development of technology, exploration, development, and production are being extended to include areas off the coast of southwest Florida and deep-water areas near the Mississippi...
1980 annual index of current earthquake literature
B.S. Hayashida, Mari L. Kauffmann, William Hung Kan Lee
1981, Open-File Report 81-454
In the past several years earthquake research has been greatly accelerated in China, Japan, the USSR, and the United States. Presently about 3,000 earthquake-related publications (including meeting abstracts) are produced yearly. In order to keep up with this current literature, a computer-based bibliographic system was implemented as part of a...
Measured sections of the Browns Park Formation (Miocene) in Moffat County, Colorado, 1980
Stanley J. Luft, William L. Thoen
1981, Open-File Report 81-171
Eight partial sections of the Browns Park Formation of Miocene age were measured in Moffat County, northwestern Colorado, during the 1980 field season, as part of a study of the stratigraphy and depositional environments of the formation. These newly measured sections are intended to complement other surface sections of the...
Hydrologic almanac of Florida
Richard C. Heath, Clyde Stuart Conover
1981, Open-File Report 81-1107
This first edition is a ready reference source of information on various facts and features about water in Florida. It is aimed primarily to help bust politicians, writers, agency officials, water managers, planners, consultants, educators, hydrologists, engineers, scientists, and the general public answer questions that arise on comparative and statistical...
Ground-water hydrology of strip-mine areas in eastern Ohio (conditions during mining of two watersheds in Coshocton and Muskingum counties)
John O. Helgesen, Allan C. Razem
1981, Open-File Report 81-913
Ground-water conditions during coal strip mining in two small watersheds are described as part of an ongoing study of effects of mining on hydrologic systems. Both watersheds were underlain by stratified sedimentary rocks containing two perched aquifers above clay beds which underlaid the major coal seams. Mining involved removing the...
Hydrology of area 3, Eastern Coal Province, Pennsylvania
William J. Herb, L. C. Shaw, Deborah E. Brown
1981, Open-File Report 81-537
Hydrologic data are presented for area 3 of the Eastern Coal Province, 4,077 square miles of the lower Allegheny River basin in western Pennsylvania. Seventy-three streams were sampled three times during the 1979 and 1980 water years for specific conductance, pH, acidity, alkalinity, dissolved and total iron, dissolved and total...
Hydrology of Area 5, Eastern Coal Province, Pennsylvania, Maryland, and West Virginia
William J. Herb, L. C. Shaw, Deborah E. Brown
1981, Open-File Report 81-538
Hydrologic data are presented for area 5 of the Eastern Coal Province, the 7,384 square-mile Monongahela River basin in western Pennsylvania, western Maryland, and north-central West Virginia. One hundred thirty-four streams were sampled about three times during the 1979 and 1980 water years for specific conductance, pH, acidity, alkalinity dissolved...
Composition of tidal flat sediments, Willapa Bay, Washington
Gary W. Hill, John L. Chinn
1981, Open-File Report 81-272
The purpose of this study was to characterize the modern sediments of sandy tidal flats in Willapa Bay, Washington based on their composition.Generally, clay comprises less than five percent of the sediment. Clay content increases upslope and up-estuary. Principal clay minerals are montmorillanite, illite, and chlorite; two clay mineral suites...
Infaunal and neoichnological characteristics of the South Texas Outer Continental Shelf
Gary W. Hill
1981, Open-File Report 81-163
The zonation of macrobenthic infauna on the South Texas Outer Continental Shelf is related to water depth and sediment facies. Five zones can be defined by species distribution and density, diversity, equitability, and biogenic sedimentary structures.The numbers of species and individuals per unit area correlate locally with substrate characteristics (particularly...
