Conjunctive-use optimization model and sustainable-yield estimation for the Sparta aquifer of southeastern Arkansas and north-central Louisiana
Paul W. McKee, Brian R. Clark, John B. Czarnecki
2004, Water-Resources Investigations Report 2003-4231
Conjunctive-use optimization modeling was done to assist water managers and planners by estimating the maximum amount of ground water that hypothetically could be withdrawn from wells within the Sparta aquifer indefinitely without violating hydraulic-head or stream-discharge constraints. The Sparta aquifer is largely a confined aquifer of regional importance that comprises...
Geophysical data reveal the crustal structure of the Alaska range orogen within the aftershock zone of the Mw 7.9 Denali fault earthquake
M. A. Fisher, N. Ratchkovski, Warren Nokleberg, Louise Pellerin, Jonathan M.G. Glen
2004, Bulletin of the Seismological Society of America (94) S107-S131
Geophysical information, including deep-crustal seismic reflection, magnetotelluric (mt), gravity, and magnetic data, cross the aftershock zone of the 3 November 2002 Mw 7.9 Denali fault earthquake. These data and aftershock seismicity, jointly interpreted, reveal the crustal structure of the right-lateral-slip Denali fault and the eastern Alaska Range orogen, as well as...
Interdisciplinary discussion of volcanic processes beneath the Long Valley Caldera-Mono Craters Area
David P. Hill, Paul Segall
2004, Eos Science News (85) 228-230
Volcanism in the Long Valley Caldera-Mono Craters (LVCMC) volcanic field in eastern California over the past 4 Ma is dominated by the 0.76 Ma caldera-forming eruption of 600 km3 of rhyolite to form the Bishop Tuff. Over the last 150 k.y., volcanism has concentrated along the Mono-Inyo chain, which extends 45...

Hydrogeology, water quality, and distribution and sources of salinity in the Floridan aquifer system, Martin and St. Lucie Counties, Florida
Ronald S. Reese
2004, Water-Resources Investigations Report 2003-4242
The Floridan aquifer system is considered to be a valuable source for agricultural and municipal water supply in Martin and St. Lucie Counties, despite its brackish water. Increased withdrawals, however, could increase salinity and threaten the quality of withdrawn water. The Floridan aquifer system consists of limestone, dolomitic limestone, and...

Evaluation of strategies for balancing water use and streamflow reductions in the upper Charles River basin, eastern Massachusetts
Jack R. Eggleston
2004, Water-Resources Investigations Report 2003-4330
The upper Charles River basin, located 30 miles southwest of Boston, Massachusetts, is experiencing water shortages during the summer. Towns in the basin have instituted water-conservation programs and water-use bans to reduce summertime water use. During July through October, streamflow in the Charles River and its tributaries regularly falls below...

Chapter 4 The meade peak member of the phosphoria formation: Temporal and spatial variations in sediment geochemistry
R.B. Perkins, David Z. Piper
2004, Handbook of Exploration and Environmental Geochemistry (8) 73-110
Variations in the geochemistry of rocks from the Meade Peak Member of the Phosphoria Formation were examined using ratios of elements associated with either the +terrigenous or marine sediment fractions. Inter-element relationships in the terrigenous fraction appear useful for chemo-stratigraphic correlation. A sharp decrease upsection in K2O/AI2O3 ratios occurs in...
