Generalized estimates from streamflow data of annual and seasonal ground-water-recharge rates for drainage basins in New Hampshire
Robert H. Flynn, Gary D. Tasker
2004, Scientific Investigations Report 2004-5019
This report presents regression equations to estimate generalized annual and seasonal ground-water-recharge rates in drainage basins in New Hampshire. The ultimate source of water for a ground-water withdrawal is aquifer recharge from a combination of precipitation on the aquifer, ground-water flow from upland basin areas, and infiltration from streambeds to...

David P. Mau, Andrew C. Ziegler, Stephen D. Porter, Larry M. Pope
2004, Scientific Investigations Report 2004-5047
Surface water in the Lake Olathe watershed, located in northeast Kansas, was sampled from June 2000 through December 2002 to characterize water-quality conditions in relation to physical properties, major ions, sediment, nutrients, selected trace elements, selected pesticides, fecal indicator bacteria, phytoplankton, and taste-and-odor compounds. In addition, two continuous real-time water-quality...
Size-frequency analysis of petroleum accumulations in selected United States plays: potential analogues for frontier areas
Emil D. Attanasi, Philip A. Freeman
2004, Open-File Report 2004-1299
This report presents the petroleum accumulation size-frequency relationships of selected mature plays assessed in the U.S. Geological Survey's 1995 National Assessment of Oil and Gas Resources. The plays provide assessors with potential analogue models from which to estimate the numbers of undiscovered accumulations in medium and smaller size categories. Each...
Assessment of water chemistry, habitat, and benthic macroinvertebrates at selected stream-quality monitoring sites in Chester County, Pennsylvania, 1998-2000
Andrew G. Reif
2004, Open-File Report 2003-499
Biological, chemical, and habitat data have been collected from a network of sites in Chester County, Pa., from 1970 to 2003 to assess stream quality. Forty sites in 6 major stream basins were sampled between 1998 and 2000. Biological data were used to determine levels of impairment in the benthic-macroinvertebrate...
Hydrogeology and ground-water-flow simulation in the former airfield area of Naval Support Activity Mid-South, Millington, Tennessee

2004, Scientific Investigations Report 2004-5040
Naval Support Activity Mid-South is a Department of the Navy base located in Millington, Tennessee. The facility was home to the Naval Aviation Technical Training Center from 1943 until 1996. As part of the Base Closure and Realignment Act of 1990, the primary training mission of the facility was realigned...
Mineral commodity profiles: nitrogen
Deborah A. Kramer
2004, Open-File Report 2004-1290
Overview -- Nitrogen (N) is an essential element of life and a part of all animal and plant proteins. As a part of the DNA and RNA molecules, nitrogen is an essential constituent of each individual's genetic blueprint. As an essential element in the chlorophyll molecule, nitrogen is vital to...
Surficial geologic map of the Ellendale quadrangle, Shelby County, Tennessee
Roy Van Arsdale
2004, Scientific Investigations Map 2836
The depiction of geology on this map is designed to aid in urban planning and analysis of potential damage in the event of strong earthquake motion. The geologic map by itself does not analyze potential earthquake damage, but is designed to be used by...
Delineation of areas contributing recharge to selected public-supply wells in Glacial Valley-Fill and Wetland Settings, Rhode Island
Paul J. Friesz
2004, Scientific Investigations Report 2004-5070
Areas contributing recharge and sources of water to one proposed and seven present public-supply wells, screened in sand and gravel deposits and clustered in three study areas, were determined on the basis of calibrated, steady-state ground-water-flow models representing average hydrologic conditions. The area contributing recharge to a well is defined...
Surficial geologic map of the Northeast Memphis quadrangle, Shelby County, Tennessee
Randel Tom Cox
2004, Scientific Investigations Map 2839
The depiction of geology on this map is designed to aid in urban planning and analysis of potential damage in the event of strong earthquake motion. The geologic map by itself does not analyze potential earthquake damage, but is designed to be used by seismologists who perform such analyses....
A formulation of directivity for earthquake sources using isochrone theory
Paul Spudich, Brian S.J. Chiou, Robert Graves, Nancy Collins, Paul Somerville
2004, Open-File Report 2004-1268
A functional form for directivity effects can be derived from isochrone theory, in which the measure of the directivity-induced amplification of an S body wave is c, the isochrone velocity. Ground displacement of the near-, intermediate-, and far-field terms of P and S waves is linear in isochrone velocity for...
Coastal circulation and sediment dynamics along West Maui, Hawaii: Part III: Flow and particulate dynamics during the 2003 summer coral spawning season
Curt D. Storlazzi, Michael E. Field, Andrea S. Ogston, Joshua B. Logan, M. Kathy Presto, Dave G. Gonzales
2004, Open-File Report 2004-1287
High-resolution measurements of currents, temperature, salinity and turbidity were made over the course of three months off West Maui in the summer and early fall of 2003 to better understand coastal dynamics in coral reef habitats. Measurements were made through the emplacement of a series of bottom-mounted instruments in water...
A dataset of magnetic susceptibility, metalization, and alteration for samples from the Stinkingwater Mining District, Absaroka Mountains, Wyoming
Mark E. Gettings
2004, Open-File Report 2004-1253
Magnetic susceptibility was measured for 700 samples of drill core from thirteen drill holes in the porphyry copper-molybdenum deposit of the Stinkingwater mining district in the Absaroka Mountains, Wyoming. Measurements were performed on splits from 3 m (10 ft) sections of pulverized core. The measurements constitute a useful dataset because...
Estimated Use of Water in the United States in 2000
Susan S. Hutson, Nancy L. Barber, Joan F. Kenny, Kristin S. Linsey, Deborah S. Lumia, Molly A. Maupin
2004, Circular 1268
Estimates of water use in the United States indicate that about 408 billion gallons per day (one thousand million gallons per day, abbreviated Bgal/d) were withdrawn for all uses during 2000. This total has varied less than 3 percent since 1985 as withdrawals have stabilized for the two largest uses?thermoelectric...

Hydraulic-Geometry Relations for Rivers in Coastal and Central Maine
Robert W. Dudley
2004, Scientific Investigations Report 2004-5042
Hydraulic-geometry relations (curves) were derived for 15 sites on 12 rivers in coastal and central Maine on the basis of site-specific (at-a-station) hydraulic-geometry relations and hydraulic models. At-a-station hydraulic-geometry curves, expressed as well-established power functions, describe the relations between channel geometry, velocity, and flow at a given point on a...
