FEMA is embarking on a map modernization program nationwide to: 1. Gather and develop...
Hydrogeologic framework refinement, ground-water flow and storage, water-chemistry analyses, and water-budget components of the Yuma area, southwestern Arizona and southeastern California
Jesse E. Dickinson, Michael Land, Claudia C. Faunt, S. A. Leake, Eric G. Reichard, John B. Fleming, D. R. Pool
2006, Scientific Investigations Report 2006-5135
The ground-water and surface-water system in the Yuma area in southwestern Arizona and southeastern California is managed intensely to meet water-delivery requirements of customers in the United States, to manage high ground-water levels in the valleys, and to maintain treaty-mandated water-quality and quantity requirements of Mexico. The following components in...
Water-level decline in the Apalachicola River, Florida, from 1954 to 2004, and effects on floodplain habitats
Helen M. Light, Kirk R. Vincent, Melanie R. Darst, Franklin D. Price
2006, Scientific Investigations Report 2006-5173
From 1954 to 2004, water levels declined in the nontidal reach of the Apalachicola River, Florida, as a result of long-term changes in stage-discharge relations. Channel widening and deepening, which occurred throughout much of the river, apparently caused the declines. The period of most rapid channel enlargement began in 1954...
Well construction information, lithologic logs, water level data, and overview of research in Handcart Gulch, Colorado: An alpine watershed affected by metalliferous hydrothermal alteration

2006, Open-File Report 2006-1189
Integrated, multidisciplinary studies of the Handcart Gulch alpine watershed provide a unique opportunity to study and characterize the geology and hydrology of an alpine watershed along the Continental Divide. The study area arose out of the donation of four abandoned, deep mineral exploration boreholes to the U.S. Geological Survey for...
Summary of the stakeholders workshop to develop a National Volcano Early Warning System (NVEWS)
Marianne Guffanti, William E. Scott, Carolyn L. Driedger, John W. Ewert
2006, Open-File Report 2006-1224
The importance of investing in monitoring, mitigation, and preparedness before natural hazards occur has been amply demonstrated by recent disasters such as the Indian Ocean Tsunami in December 2004 and Hurricane Katrina in August 2005. Playing catch-up with hazardous natural phenomena such as these limits our ability to work...

George N. Breit, James C. Yount, Nehal Uddin, Ad. Atual Muneem, Heather Lowers, Rhonda L. Driscoll, John W. Whitney
2006, Open-File Report 2006-1222
Processes active within sediment of the Bengal delta have attracted world concern because of the locally high content of arsenic dissolved in ground water drawn from that sediment. Sediment samples were collected from two boreholes in Srirampur village, Kachua upazila, Chandphur district, Bangladesh, to investigate the processes contributing to arsenic...
Use of dye tracing to determine ground-water movement to Mammoth Crystal Springs, Sylvan Pass area, Yellowstone National Park, Wyoming
Lawrence E. Spangler, David D. Susong
2006, Scientific Investigations Report 2006-5126
At the request of and in cooperation with the Geology Program at Yellowstone National Park, the U.S. Geological Survey conducted a hydrologic investigation of the Sylvan Pass area in June 2005 to determine the relation between surface water and ground-water flow to Mammoth Crystal Springs. Results of a dye-tracing investigation...
Toward "Supervolcano" technology
Gillian R. Foulger
2006, Science (313) 768-769
In addition to depicting the ultimate volcano-eruption horror story, the recent Discovery Channel/BBC coproduction “Supervolcano” speculates about what technology will be available to the geophysicist in 2025 to monitor active volcanoes. The result is a fictional Virtual Geophysical Laboratory that, when fed the right data, predicts eruption scenarios, thereby providing...
