Geothermal systems of northern Nevada
Richard Kenneth Hose, Bruce Edward Taylor
1974, Open-File Report 74-271
Hot springs are numerous and nearly uniformly distributed in northern Nevada. Most occur on the flanks of basins, along Basin and Range (late Miocene to Holocene) faults, while some occur in the inner parts of the basins. Surface temperatures of the springs range from slightly above ambient to, boiling; some...
Geological Survey published reports on Alaska, 1884-1914, indexed by quadrangle
Edward Huntington Cobb
1974, Open-File Report 74-345
Geological Survey reports published as Annual Reports, Monographs, Special Reports, Professional Papers, Bulletins, and Water Supply Papers are listed by the quadrangles (scale 1:250,000) into which Alaska has been divided for topographic mapping (p. 2). This index does not include any reports that deal solely with administrative matters.Reports that deal...
Analog-model studies of ground-water hydrology in the Houston District, Texas
Donald G. Jorgensen
1974, Open-File Report 74-113
The major water-bearing units in the Houston district are the Chicot and the Evangeline aquifers. The Chicot aquifer overlies the Evangeline aquifer, which is underlain by the Burkeville confining layer. Both aquifers consist of unconsolidated and discontinuous layers of sand and clay that dip toward the Gulf of Mexico. Heavy...
A program to compute aquifer-response coefficients
Thomas Maddock
1974, Open-File Report 75-612
An alternating direction technique is used to solve finite difference equations approximating the flow of water in an aquifer. The solutions produce response coefficients relating pumping from wells to drawdowns within those wells. The product of the response coefficient with the pumping values produces a linear algebraic technological function that...
