Hydrogeology, water quality, and water-resources development potential of the upper Floridan Aquifer in the Valdosta area, south-central Georgia
J. B. McConnell, C.M. Hacke
1993, Water-Resources Investigations Report 93-4044
Water quality in the Upper Floridan aquifer in the Valdosta, Georgia area is adversely affected by direct recharge from the Withlacoochee River. Water enters the aquifer along a short reach of the river where sinkholes have formed in the stream bed. The water receives little filtration as it recharges the...
Tidal and residual currents measured by an acoustic doppler current profiler at the west end of Carquinez Strait, San Francisco Bay, California, March to November 1988
J.R. Burau, M.R. Simpson, R. T. Cheng
1993, Water-Resources Investigations Report 92-4064
Water-velocity profiles were collected at the west end of Carquinez Strait, San Francisco Bay, California, from March to November 1988, using an acoustic Doppler current profiler (ADCP). These data are a series of 10-minute-averaged water velocities collected at 1-meter vertical intervals (bins) in the 16.8-meter water column, beginning 2.1 meters...
Method for predicting water demand for crop uses in New Jersey in 1990, 2000, 2010, and 2020, and for estimating water use for livestock and selected sectors of the food-processing industry in New Jersey in 1987
R.M. Clawges, E.O. Titus
1993, Water-Resources Investigations Report 92-4145
A method was developed to predict water demand for crop uses in New Jersey. A separate method was developed to estimate water use for livestock and selected sectors of the food-processing industry in 1987. Predictions of water demand for field- grown crops in New Jersey were made for...
Hydrology and water quality of Reedy Creek in the Reedy Creek Improvement District, central Florida, 1986-89
P. S. Hampson
1993, Water-Resources Investigations Report 93-4006
The Reedy Creek Improvement District encompasses an area of about 43 sq mi in southwestern Orange and northwestern Osceola Counties in central Florida. The District operates a wastewater-treatment plant that discharges through two forested wetland areas and a percolation-pond system into Reedy Creek. Discharges from these wetland systems provide a...
Hydrologic conditions in the Jacobs Creek, Stony Brook, and Beden Brook drainage basins, west-central New Jersey, 1986-88
Eric Jacobsen, M. A. Hardy, B. A. Kurtz
1993, Water-Resources Investigations Report 91-4164
Data on the quantity and quality of groundwater and surface water in the drainage basins of Jacobs Creek, Stony Brook, and Beden Brook upstream from U.S. Route 206 in west-central New Jersey were collected from October 1, 1986, through September 30, 1988. Water levels measured in 74 wells ranged from...
Recent developments in three-dimensional numerical estuarine models
Ralph T. Cheng, Peter E. Smith, Vincenzo Casulli
1993, Conference Paper, Hydraulic Engineers
For a fixed cost, computing power increases 5 to 10 times every five years. The readily available computing resources have inspired new modal formulations and innovative model applications. Significant progress has been advanced in three-dimensional numerical estuarine modeling within the past three or four years. This paper attempts to review...
Reconnaissance of geology and water resources along the north flank of the Sweet Grass Hills, north-central Montana
L.K. Tuck
1993, Water-Resources Investigations Report 93-4026
Mississippian through Holocene rocks crop out in the area. Emplaced Tertiary igneous rocks have caused structural deformation. Aquifers are Holocene alluvium, Quaternary interstratified sand and gravel, and Upper Cretaceous Judith River Formation and Virgelle Sandstone Member of Eagle Sandstone. Recharge to each aquifer is through combinations of infiltration of precipitation,...
Effects of focused recharge on the transport of agricultural chemicals at the Princeton, Minnesota Management Systems Evaluation Area, 1991-92
G. N. Delin, M.K. Landon
1993, Open-File Report 93-42
Rates of water movement through the unsaturated zone greatly affect the amount and concentrations of agricultural chemicals that may reach the water table. For example, recharge can flush chemicals to the water table which have accumulated in the unsaturated zone during dry periods. A better understanding of how topography influences...
Maps showing mineral resource assessment for porphyry and stockwork deposits of copper, molybdenum, and tungsten and for stockwork and disseminated deposits of gold and silver in the Butte 1° x 2° quadrangle, Montana
J. E. Elliott, S. H. Moll, C. A. Wallace, G. K. Lee, J.C. Antweiler, D. J. Lidke, L. C. Rowan, W. F. Hanna, C. M. Trautwein, John L. Dwyer
1993, IMAP 2050-F
This report documents the assessment for potential occurrences of undiscovered porphyry and stockwork deposits of copper, molybdenum, and tungsten (porphyry Cu-Mo-W) and stockwork and disseminated deposits of gold and silver (disseminated Au-Ag) in the Butte 1 °X2° quadrangle. The Butte quadrangle, in west-central Montana, is one of the best known...
Methods for collecting benthic invertebrate samples as part of the National Water-Quality Assessment Program
Thomas F. Cuffney, Martin E. Gurtz, Michael R. Meador
1993, Open-File Report 93-406
Benthic invertebrate communities are evaluated as part of the ecological survey component of the U.S. Geological Survey's National Water-Quality Assessment Program. These biological data are collected along with physical and chemical data to assess water-quality conditions and to develop an understanding of the factors that affect water-quality conditions locally, regionally,...
Map showing sediment isopachs in the deep-sea basins of the Pacific Continental Margin, Strait of Juan de Fuca to Cape Mendocino
J.V. Gardner, D.A. Cacchione, D.E. Drake, B. D. Edwards, M.E. Field, M. A. Hampton, Herman A. Karl, Neil H. Kenyon, D.G. Masson, D. S. McCulloch, M. S. Grim
1993, IMAP 2091-A
The U.S. Geological Survey conducted a series of cruises, EEZSCAN 84 (EEZ-SCAN 84 Scientific Staff, 1986), to collect reconnaissance data on the newly proclaimed Exclusive Economic Zone (EEZ), the area out to 200 nautical miles from the coastline of the United States. The cruises systematically surveyed the entire conterminous United...
Preliminary evaluation of hydrogeology and ground-water quality in valley sediments in the vicinity of Killarney Lake, Kootenai County, Idaho
T.B. Spruill
1993, Water-Resources Investigations Report 93-4091
Ground water near Killarney Lake in the Coeur d'Alene River Valley, Idaho, contains arsenic, cadmium, lead, and zinc in concentrations that would make it unsuitable for a potable (drinking water) supply. Dissolved arsenic in one well was more than six times higher than the U.S. Environmental Protection Agency' s maximum...
