Characterization of selected biological, chemical, and physical conditions at fixed sites in the Upper Colorado River basin, Colorado, 1995-98
Jeffrey R. Deacon, Scott V. Mize, Norman E. Spahr
1999, Water-Resources Investigations Report 99-4181
Biological community samples were collected at 15 sites in the Upper Colorado River Basin (UCOL) in Colorado as part of the National Water-Quality Assessment (NAWQA) Program. Sites sampled in two physiographic provinces, the Southern Rocky Mountains and the Colorado Plateau, represented agriculture, mining, urban and recreation, and mixed land uses...
Baseline water quality and preliminary effects of artificial recharge on ground water, south-central Kansas, 1995–98
Andrew C. Ziegler, Victoria G. Christensen, Heather C. Ross
1999, Water-Resources Investigations Report 99-4250
To investigate the feasbility of artificial recharge as a method of meeting future water-supply needs and to protect the Equus Beds aquifer from saltwater intrusion from natural and anthropogenic sources to the west, the Equus Beds Ground-Water Recharge from Demonstration Project was begun in 1995. The project is a cooperative...

Inorganic chemistry of water and bed sediment in selected tributaries of the south Umpqua River, Oregon, 1998
Stephen R. Hinkle
1999, Water-Resources Investigations Report 99-4196
Ten sites on small South Umpqua River tributaries were sampled for inorganic constituents in water and streambed sediment. In aqueous samples, high concentrations (concentrations exceeding U.S. Environmental Protection Agency criterion continuous concentration for the protection of aquatic life) of zinc, copper, and cadmium were detected in Middle Creek at Silver...
Learning to live with geologic and hydrologic hazards

The Seattle, Washington, area is known for its livability and its magnificent natural setting. The city and nearby communities are surrounded by an abundance of rivers and lakes and by the bays of Puget Sound. Two majestic mountain ranges, the Olympics and the Cascades, rim the region. These splendid natural...
Generalized water-table and water-level data at the US Air Force plant 42 and vicinity, Palmdale, California, March-April, 1997

1999, Water-Resources Investigations Report 99-4262
The U.S. Air Force Plant 42 (Plant 42) which is in the Antelope Valley about 1.5 miles northeast of Palmdale and 3 miles southeast of Lancaster in Los Angeles County. Historically, ground water has been the primary source of water owing, in large part, to the scarcity of surface water...

A physically-based earthquake recurrence model for estimation of long-term earthquake probabilities
William L. Ellsworth, Mark V. Matthews, Robert M. Nadeau, Stuart P. Nishenko, Paul A. Reasenberg, Robert W. Simpson
1999, Open-File Report 99-522
A physically-motivated model for earthquake recurrence based on the Brownian relaxation oscillator is introduced. The renewal process defining this point process model can be described by the steady rise of a state variable from the ground state to failure threshold as modulated by Brownian motion. Failure times in this model...
USGS Map-on-Demand Printing
Water Resources Division, U.S. Geological Survey
1999, Fact Sheet 074-99
Currently, the U.S. Geological Survey (USGS) uses conventional lithographic printing techniques to produce paper copies of most of its mapping products. This practice is not economical for those products that are in low demand. With the advent of newer technologies, high-speed, large-format printers have been coupled with innovative computer software...

Areal-reduction factors for the precipitation of the 1-day design storm in Texas
William H. Asquith
1999, Water-Resources Investigations Report 99-4267
The reduction of the precipitation depth from a design storm for a point to an effective (mean) depth over a watershed often is important for cost-effective design of hydraulic structures by reducing the volume of precipitation. A design storm for a point is the depth of precipitation that has a...
