Watershed analysis of the Salmon River watershed, Washington : hydrology
William R. Bidlake
2003, Water-Resources Investigations Report 2003-4204
The U.S. Geological Survey analyzed selected hydrologic conditions as part of a watershed analysis of the Salmon River watershed, Washington, conducted by the Quinault Indian Nation. The selected hydrologic conditions were analyzed according to a framework of hydrologic key questions that were identified for the watershed. The key questions were...
Evaluation of Diazinon and Chlorpyrifos Concentrations and Loads, and other Pesticide Concentrations, at Selected Sites in the San Joaquin Valley, California, April to August, 2001
Joseph L. Domagalski, Cathy Munday
2003, Water-Resources Investigations Report 2003-4088
Twelve sites in the San Joaquin Valley of California were monitored weekly during the growing and irrigation season of 2001 for a total of 51 pesticides and pesticide degradation products, with primary interest on the concentration, load, and basin yield of organophosphorus insecticides, especially diazinon and chlorpyrifos. Diazinon was detected...

2003, Water-Resources Investigations Report 2003-4193
The Christina River Basin drains 565 square miles (mi2) in Pennsylvania and Delaware and includes the major subbasins of Brandywine Creek, Red Clay Creek, White Clay Creek, and Christina River. The Christina River subbasin (exclusive of the Brandywine, Red Clay, and White Clay Creek subbasins) drains an area of 76...
Comparison between agricultural and urban ground-water quality in the Mobile River Basin, 1999–2001
James L. Robinson
2003, Water-Resources Investigations Report 2003-4182
The Black Warrior River aquifer is a major source of public water supply in the Mobile River Basin. The aquifer outcrop trends northwest - southeast across Mississippi and Alabama. A relatively thin shallow aquifer overlies and recharges the Black Warrior River aquifer in the flood plains and terraces of the...

Natural remediation potential of arsenic-contaminated ground water
Kenneth G. Stollenwerk, John A. Colman
2003, Book chapter, Arsenic in Ground Water
Migration of leachate from a municipal landfill in Saco, Maine has resulted in arsenic concentrations in ground water as high as 647 μg/L. Laboratory experimental data indicate the primary source of arsenic to be reductive dissolution of arsenic-enriched iron oxyhydroxides in the aquifer by organic carbon in landfill leachate. A core...
Electrical imaging of tracer migration at the Massachusetts Military Reservation, Cape Cod
Kamini Singha, Andrew Binley, John W. Lane Jr., Steven M. Gorelick
2003, Conference Paper, Proceedings: Symposium on the Application of Geophysics to Engineering and Environmental Problems (SAGEEP)
Electrical resistivity tomography (ERT) is examined as a method to provide spatially continuous information about aquifer properties through imaging of tracer flow and transport in an unconfined aquifer. Field data were collected at the Massachusetts Military Reservation, Cape Cod, Massachusetts, during the summer of 2002. High resolution images in both...
Object-based inversion of crosswell radar tomography data to monitor vegetable-oil injection experiment
John W. Lane Jr., Frederick D. Day-Lewis, Roelof J. Versteeg, C.C. Casey
2003, Conference Paper, Proceedings: Symposium on the Application of Geophysics to Engineering and Environmental Problems (SAGEEP)
Crosswell radar tomography methods can be used to dynamically image ground-water flow and mass transport associated with tracer tests, hydraulic tests, and natural physical processes. Dynamic imaging can be used to identify preferential flow paths and to help characterize complex aquifer heterogeneity. Unfortunately, because the raypath...
Arsenic in ground water used for drinking water in the United States
Sarah J. Ryker
2003, Book chapter, Arsenic in Ground Water
The U.S. Environmental Protection Agency recently established a new maximum contaminant level of 10 micrograms per liter for arsenic in drinking water in the United States. Ground water is the primary source of drinking water for half the population of the United States. Several national assessments have found that high...

Continuous-resistivity profiling for coastal ground-water investigations: Three case studies
Marcel Belaval, John W. Lane Jr., David P. Lesmes, G. C. Kineke
2003, Conference Paper, Proceedings: Symposium on the Application of Geophysics to Engineering and Environmental Problems (SAGEEP)
Continuous-resistivity profiling (CRP) was used at three sites to investigate submarine groundwater discharge (SGD) and to delineate the subsurface saltwater/freshwater interface. At the first site, in Georgetown, South Carolina, CRP was used to locate possible areas of SGD in the Winyah Bay estuary. The data show evidence of SGD in...
Preparing for climate change: The potential consequences of climate variability and change
Zhu Ning, R. E. Turner, T.W. Doyle, Kamran Abdollahi, Alma Thornton, Enrique Reyes, D. Justic, E. Swenson, Wael Khairy, Kam-Biu Liu
2003, Report
Over the past decades, scientific research has greatly advanced the knowledge and understanding of global environmental change. Research supported by the U. S. Global Change Research Programme (USGCRP) and research and assessment results by international organizations such as the Intergovernmental Panel on Climate Change (IPCC), the World Climate Research Program (WCRP), and...

The seagrasses of the Gulf of Mexico
C.P. Onuf, R. C. Phillips, C. A. Moncreiff, A. Raz-Guzman, Jorge A Herrera-Silveira
2003, Book chapter, World Atlas of Seagrasses
The Gulf of Mexico is a vast basin of water, spanning 12° of latitude, from 18° to 30°N. and 17° of longitude, from 81° to 98°W. It is bisected by the Tropic of Cancer and is largely subtropical; however, along the northern edge, up to five days with freezing temperatures are probable on an...
Understanding climatic impacts, vulnerabilities, and adaptation in the United States: Building a capacity for assessment

2003, Climatic Change (57) 9-42
Based on the experience of the U.S. National Assessment, we propose a program of research and analysis to advance capability for assessment of climate impacts, vulnerabilities, and adaptation options. We identify specific priorities for scientific research on the responses of ecological and socioeconomic systems to climate and other stresses; for...

2003, Natural Resources Research (12) 303-320
As water quantity and quality problems become increasingly severe, accurate prediction and effective management of scarcer water resources will become critical. In this paper, the successful application of artificial neural network (ANN) technology is described for three types of groundwater prediction and management problems. In the first example, an ANN...
