Publications related to the National Water Data Exchange (NAWDEX); 1971-81
B. M. Myers (compiler)
1982, Open-File Report 82-151
The National Water Data Exchange (NAWDEX), formally established in January 1976, is a national confederation of water-oriented organizations working together to improve access to water data. Its primary objective is to assist users of water data in the identification, location, and acquisition of needed water data or water-related data. NAWDEX...
Documentation and user's guide for interactive spectral analysis and filter program package useful in the processing of seismic reflection data
J. J. Miller
1982, Open-File Report 82-744
The spectral analysis and filter program package is written in the BASIC language for the HP-9845T desktop computer. The program's main purpose is to perform spectral analyses on digitized time-domain data. In addition, band-pass filtering of the data can be performed in the time domain. Various other processes such as...
Assessment of hydrologic conditions in potential coal-lease tracts in the Warrior coal field, Alabama
Celso Puente, John F. Newton, Roy H. Bingham
1982, Open-File Report 81-540
Assessing the hydrology of potential Federal coal-lease tracts, because of their dissemination and limited data, requires some predictive capability. Four tracts assessed were located in the outcrop of three coal groups and of other relatively impermeable rocks in the Pottsville Formation. Physical settings of the tracts and most other areas...
Hydrology of potential mining areas in the Warrior coal field, Alabama
Celso Puente, J.G. Newton
1982, Open-File Report 82-105
Hydrologic data for four small basins and for numerous other sites in the Warrior coal field are used to define the potential impact of surface mining on water resources. Bear and Blue Creek basins are underlain predominantly by relatively impermeable consolidated rocks in the Pottsville Formation. Turkey and Yellow Creek...
Changes in flood response of the Red River of the North Basin, North Dakota-Minnesota
Jeffrey E. Miller, Dale L. Frink
1982, Open-File Report 82-774
The magnitude and frequency of large floods that have occurred in recent years in the basin of the Red River of the North have caused concern that land-use changes and manmade drainage have increased flooding. This study was undertaken to determine if any changes in flood response of the Red...
Summary appraisals of the nation's ground-water resources – New England region
Allen Sinnott
1982, Professional Paper 813-T
The New England Region has a total area of about 62,400 square miles (160,000 km2) and includes the States of Maine and New Hampshire, eastern Vermont, most of Massachusetts and Connecticut, all of Rhode Island, and a small part of southeastern New York. The longest stream is the Connecticut River,...
The brachiopod genera Hebertella, Dalmanella, and Heterorthina from the Ordovician of Kentucky
L.G. Walker
1982, Professional Paper 1066-M
The orthid brachiopod genera Hebertella, Dalmanella, and Heterorthina are abundant in Middle and Upper Ordovician strata in Kentucky. 'Nine species are described: Hebertella frankfortensis Foerste; H. parksensis Foerste; H. occidentalis (Hall); Dalmanella bassleri Foerste; D. fertilis (Ulrich); D. meeki (Miller); D. multisecta (Meek); D. sulcata Cooper; and Heterorthina macfarlani Neuman....
An evaluation of Idaho stream-gaging networks
E.W. Quillian, W. A. Harenberg
1982, Open-File Report 82-865
Network Analysis for Regional Information (NARI) and the Cost-Effectiveness Procedure were tested by applying them to stream-gaging networks in Idaho. NARI was used to determine network design strategies that would maximize the value of additional data. Value of data was measured as the decrease in the probable true standards error...
Mineral resource potential map of the Rock Pile Mountain Wilderness Study area, Madison County, Missouri
Walden P. Pratt, Ralph L. Erickson, Clarence Ellis
1982, Miscellaneous Field Studies Map 1339-B
Although the Rock Pile Mountain Wilderness Study Area is within the general boundary of the Southeast Missouri mining district, it has no record of mineral production and there is no mining or prospecting activity at present. Exploratory drill holes on private land along the west side of the area encountered...
Reconnaissance of stream biota and physical and chemical water quality in areas of selected land use in the coal-mining region, southwestern Indiana, 1979-80
D. J. Wangsness
1982, Open-File Report 82-566
To help meet the goals of the Surface-Mining Control and Reclamation Act of 1977, the U.S. Geological Survey is assessing the physical, chemical, and biological characteristics of surface water within the coal-mining region of southwestern Indiana. This report discusses benthic-invertebrate and periphyticalgal communities in streams draining homogeneous-agricultural, forested, active/reclaimed-mine, reclaimed-mine,...
Determination of the true density of pulverized coal samples
R.W. Stanton
1982, Open-File Report 82-835
A method using the gas-comparison pycnometer with helium gas as the penetrating medium measures precisely the true volume of a pulverized coal sample. The true density of a solid is calculated as the true unit volume of the solid exclusive of its pore space which is divided into the weight...
A national water-use information program
William B. Mann, John E. Moore, Edith B. Chase
1982, Open-File Report 82-862
The U.S. Geological Survey has compiled estimates of water use every five years since 1950. These estimates have been derived from many sources, and have a wide range of accuracy. Therefore, they fall short of providing a national data base that is both current and reliable. In 1977, the Congress...
Maps showing locations and descriptions of radiocarbon-dated samples from central and northern California
Carol A. Price
1982, Miscellaneous Field Studies Map 1321
This compilation includes radiocarbon dates and other pertinent information about samples from northern and central California, principally north of latitude 36°, drawn largely from Radiocarbon, Science, unpublished data of U.S. Geological Survey geologists, and other published and unpublished data brought to the author's attention as of January 1981. It includes...
