J. F. Ruhl
1995, Water-Resources Investigations Report 94-4199
The Grand Portage Indian Reservation Tribal Council needs information about the availability and quality of the ground water in the Reservation to develop, protect, and manage this resource for future use. The U.S. Geological Survey, in cooperation with the Grand Portage Indian Reservation Tribal Council, did a three-year study of...

1995, Groundwater (33) 653-661
Transport of the bacteriophage PRD-1, bacteria, and latex microspheres was studied in a sandy aquifer under natural-gradient conditions. The field injection was carried out at the U.S. Geological Survey's Toxic Substances Hydrology research site on Cape Cod. The three colloids and a salt tracer (Br−) moved along the same path....
Steady-state simulation of ground-water flow in the Blaine Aquifer, southwestern Oklahoma and northwestern Texas
Donna L. Runkle, J. S. McLean
1995, Open-File Report 94-387
A generalized finite-difference model was prepared for the Blaine aquifer in southwestern Oklahoma and northwestern Texas. This report releases the model for use and modification. A grid of 1-square-mile nodes was established over the area, with 1,030 of the nodes actively simulated in the model. The steady-state model simulation used...
Nitrate transport and transformation processes in unsaturated porous media
James A. Tindall, Robin L. Petrusak, Peter B. McMahon
1995, Journal of Hydrology (169) 51-94
A series of experiments was conducted on two contrasting agricultural soils to observe the influence of soil texture, preferential flow, and plants on nitrate transport and denitrification under unsaturated conditions. Calcium nitrate fertilizer was applied to the surface of four large undisturbed soil cores (30 cm diameter by 40 cm...
Wind shear stress measurements in a coastal marsh during Hurricane Andrew
J. R. Dingler, S.A. Hsu, A. Lee Foote
1995, Journal of Coastal Research 295-305
Hurricane Andrew produced changes to the Louisiana wetlands not normally observed after lesser, more common storms. For example, the <25 m/s wind speeds generated by cold fronts and winter storms, and any accompanying storm surge, do not cause substantial, wide-spread alteration of marsh vegetation. During Hurricane Andrew, however, the wind,...
Structural impact of hurricane Andrew on the forested wetlands of the Atchaflaya Basin in South Louisiana
Thomas W. Doyle, Bobby D. Keeland, Lance E. Gorham, Darrin J. Johnson
1995, Journal of Coastal Research 354-364
On August 26, 1992, Hurricane Andrew hit the Louisiana coast and traversed a large portion of the lower Atchafalaya Basin, bounding the largest remaining tract of cypress-tupelo and bottomland hardwood swamp in the United States. Permanent field sites were established following the hurricane to assess the extent of forest damage...

Dissolved-solids contribution to the Colorado River from public lands in southeastern Nevada, through September 1993
C.L. Westenburg
1995, Water-Resources Investigations Report 94-4210
The Bureau of Land Management administers about 9,300 square miles of public lands in southeastern Nevada that are part of the Colorado River Basin. The U.S. Geological Survey, in cooperation with the Bureau of Land Management, began a 5-year program in October 1988 to assess the contribution of dissolved solids...

Regional assessment of NLEAP NO3-N leaching indices
B.K. Wylie, M.J. Shaffer, M.D. Hall
1995, Journal of the American Water Resources Association (31) 399-408
Nonpoint source ground water contamination by nitrate nitrogen (NO3-N) leached from agricultural lands can be substantial and increase health risks to humans and animals. Accurate and rapid methods are needed to identify and map localities that have a high potential for contamination of shallow aquifers with NO3-N leached from agriculture....
Factors affecting water quality and net flux of solutes in two stream basins in the Quabbin Reservoir drainage basin, central Massachusetts, 1983-85
R. L. Rittmaster, J. B. Shanley
1995, Water-Resources Investigations Report 94-4003
The factors that affect stream-water quality were studied at West Branch Swift River (Swift River), and East Branch Fever Brook (Fever Brook), two forested watersheds that drain into the Quabbin Reservoir, central Massachusetts, from December 1983 through August 1985. Spatial and temporal variations of chemistry of precipitation, surface water; and...
Lead isotopes from the Upper Mississippi Valley district: A regional perspective
Timothy M. Millen, Robert E. Zartman, Allen Van Heyl
1995, Bulletin 2094-B
New lead isotopic data on galena from within and peripheral to the Upper Mississippi Valley lead-zinc district make it possible, by extending coverage to outlying locations, to trace the pathway traversed by the mineralizing fluids beyond the boundary of the main district. All but one of the samples exhibit elevated...

Water, energy, and biogeochemical budget research at Sleepers River Research Watershed, Vermont
James B. Shanley, E.T. Sundquist, Carol Kendall
1995, Open-File Report 94-475
The U.S. Geological Survey has selected the Sleepers River Research Watershed (Sleepers River) near Danville, Vt., as one of five sites for the investigation of Water, Energy, and Biogeochemical Budgets (WEBB). Sleepers River was chosen because it is a well-designed outdoor laboratory with a long history of hydrologic data collection...
Sedimentology, Behavior, and Hazards of Debris Flows at Mount Rainier, Washington
K. M. Scott, J.W. Vallance, P. T. Pringle
1995, Professional Paper 1547
Mount Rainier is potentially the most dangerous volcano in the Cascade Range because of its great height, frequent earthquakes, active hydrothermal system, and extensive glacier mantle. Many debris flows and their distal phases have inundated areas far from the volcano during postglacial time. Two types of debris flows, cohesive and...
Relation of precipitation quality to storm type, and deposition of dissolved chemical constituents from precipitation in Massachusetts, 1983-85
F. B. Gay, Charles S. Melching
1995, Water-Resources Investigations Report 94-4224
Precipitation samples were collected for 83 storms at a rural inland site in Princeton, Mass., and 73 storms at a rural coastal site in Truro, Mass., to examine the quality of precipitation from storms and relate quality to three storm types (oceanic cyclone, continental cyclone, and cold front). At the...

Use of fathometers and electrical-conductivity probes to monitor riverbed scour at bridge piers
Donald C. Hayes, F.E. Drummond
1995, Water-Resources Investigations Report 94-4164
Two methods, a fathometer system and an electrical- conductivity probe system, were developed to monitor scour at bridge piers. The scour-monitoring systems consisted of a sensor (fathometer or electrical- conductivity probe), power supply, data logger, relay, and system program. The fathometer system was installed and tested at a bridge over...
Chemical evolution of groundwater near a sinkhole lake, northern Florida: 1. Flow patterns, age of groundwater, and influence of lakewater leakage
Brian G. Katz, Terrie M. Lee, Niel Plummer, Eurybiades Busenberg
1995, Water Resources Research (31) 1549-1564
Leakage from sinkhole lakes significantly influences recharge to the Upper Floridan aquifer in poorly confined sediments in northern Florida. Environmental isotopes (oxygen 18, deuterium, and tritium), chlorofluorocarbons (CFCs: CFC-11, CCl3F; CFC-12, CCl2F2; and CFC-113, C2Cl3F3), and solute tracers were used to investigate groundwater flow patterns near Lake Barco, a seepage...
