The program is conducted by the U.S. Geological Survey in cooperation with the Wyoming State Engineer and the city...
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...
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...
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...

1982, Open-File Report 82-136
More than 11,000 km of high-resolution seismic-reflection data, 325 km of mid-range sidescan-sonar data, and 500 km of long-range sidescan-sonar data were examined and used to construct an environmental geology map of the Continental Shelf, Slope, and Rise for the area of the U.S. Atlantic margin between lats. 32?N. and...
Preliminary appraisal of gravity and magnetic data at Syncline Ridge, western Yucca Flat, Nevada Test Site, Nye County, Nevada
David A. Ponce, William F. Hanna
1982, Open-File Report 82-931
A gravity and magnetic study of the Syncline Ridge area was conducted as part of an investigation of argillite rocks of the Eleana Formation under consideration as a medium for the possible storage of high-level radioactive waste. Bouguer gravity anomaly data, viewed in light of densities obtained by gamma-gamma logs...
A recommended procedure for the preparation of oriented clay-mineral specimens for X-ray diffraction analysis; modifications to Drever's filter-membrane peel technique
R. M. Pollastro
1982, Open-File Report 82-71
Extremely well-oriented clay mineral mounts for X-ray diffraction analysis can be prepared quickly and without introducing segregation using the filter-membrane peel technique. Mounting problems encountered with smectite-rich samples can be resolved by using minimal sample and partial air-drying of the clay film before transfer to a glass slide. Samples containing...
Disturbed zones: Indicators of deep-seated subsurface faults in the Valley and Ridge and Appalachian structural front of Pennsylvania
Howard A. Pohn, Terri L. Purdy
1982, Open-File Report 82-967
Field studies of geologic structures in the Valley and Ridge and adjacent parts of the Appalachian Plateau provinces in Pennsylvania have shown a new type of structure, formerly poorly understood and frequently unmapped, is a significant indicator of deep-seated subsurface faulting. These structures, herein called disturbed zones, are formed by...

A hybrid structure for the storage and manipulation of very large spatial data sets
Donna J. Peuquet
1982, Open-File Report 82-816
The map data input and output problem for geographic information systems is rapidly diminishing with the increasing availability of mass digitizing, direct spatial data capture and graphics hardware based on raster technology. Although a large number of efficient raster-based algorithms exist for performing a wide variety of common tasks on...
