The USGS role in mapping the nation's submerged lands
Bill Schwab, John Haines
2004, Fact Sheet 2004-3082
The seabed provides habitat for a diverse marine life having commercial, recreational, and intrinsic value. The habitat value of the seabed is largely a function of the geological structure and related geological, biological, oceanologic, and geochemical processes. Of equal importance, the nation's submerged lands contain energy and mineral resources and...

2004, Scientific Investigations Report 2004-5246
Domestic wells tapping shallow ground water are an important source of potable water for rural residents of Lahontan Valley. For this reason, the public has expressed concern over the acquisition of water rights directed by Public Law 101-618. The acquisition has resulted in removal of land from irrigation, which could...

2004, Scientific Investigations Report 2004-5192
Travel times for seven streams tributary to the Mississippi River from St. Cloud to Minneapolis, Minnesota, were estimated for three flow conditions; low, median, and high. Travel times were estimated for Sauk, Elk, Crow, and Rum Rivers, and Elm, Coon, and Rice Creeks. Regression equations based on watershed characteristics of...

Simulation of solute transport of tetrachloroethylene in ground water of the glacial-drift aquifer at the Savage Municipal Well Superfund Site, Milford, New Hampshire, 1960-2000
Philip T. Harte
2004, Scientific Investigations Report 2004-5176
The Savage Municipal Well Superfund site, named after the former municipal water-supply well for the town of Milford, is underlain by a 0.5-square mile plume of volatile organic compounds (VOCs), primarily tetrachloroethylene (PCE). The plume occurs mostly within a highly transmissive sand-and-gravel unit, but also extends to an underlying till...
Death Valley regional ground-water flow system, Nevada and California -- hydrogeologic framework and transient ground-water flow model
Wayne R. Belcher, editor(s)
2004, Scientific Investigations Report 2004-5205
A numerical three-dimensional (3D) transient ground-water flow model of the Death Valley region was developed by the U.S. Geological Survey for the U.S. Department of Energy programs at the Nevada Test Site and at Yucca Mountain, Nevada. Decades of study of aspects of the ground-water flow system and previous less...
Modeling of the Climax Stock and Related Plutons Based on the Inversion of Magnetic Data, Southwest Nevada

2004, Open-File Report 2004-1345
Two models of the Climax and Gold Meadows stocks were generated using a new method of magnetic inversion modeling based on the pseudogravity anomaly. The first model examined the shape of the two stocks and their connection at depth, concluding that the stocks are connected -4000 m below the ground...

Simulated peak inflows for glacier dammed Russell Fiord, near Yakutat, Alaska
Edward G. Neal
2004, Scientific Investigations Report 2004-5234
In June 2002, Hubbard Glacier advanced across the entrance to 35-mile-long Russell Fiord creating a glacier-dammed lake. After closure of the ice and moraine dam, runoff from mountain streams and glacial melt caused the level in ?Russell Lake? to rise until it eventually breached the dam on August 14, 2002....
