South Fork Iowa River watershed selected for a national water-quality study
M.L. Erwin, Stephen J. Kalkhoff
2005, Fact Sheet 2005-3064
The U.S. Geological Survey (USGS) is studying seven watersheds across the Nation to better understand how natural factors and agricultural management practices (AMPs) affect the transport of water and chemicals. Natural factors include climate and landscape (soil type, topography, geology), and AMPs include practices related to tillage, irrigation, and chemical...

2005, Fact Sheet 2004-3067
The U.S. Environmental Protection Agency?s (USEPA) Regional Vulnerability Assessment (ReVA) Program has developed a set of statistical tools to support regional-scale, integrated ecological risk-assessment studies. One of these tools, developed by the U.S. Geological Survey (USGS), is used with available water-quality data obtained from USGS National Water-Quality Assessment (NAWQA) and...
Acoustic doppler velocity monitoring within Main Spring, Barton Springs, Austin, Texas, April-September 2004-enhancing the accuracy of springflow data
W.H. Asquith, M.O. Gary
2005, Fact Sheet 2005-3044
Acoustic Doppler velocity (ADV) meters are sophisticated underwater monitoring instruments that use sound waves to measure water velocity in as many as three directions. In April 2004, an ADV meter was installed inside the principal orifice and discharge point of Main Spring at Barton Springs in Austin, Texas. This instrument...

Did you feel it? : citizens contribute to earthquake science
David J. Wald, James W. Dewey
2005, Fact Sheet 2005-3016
Since the early 1990s, the magnitude and location of an earthquake have been available within minutes on the Internet. Now, as a result of work by the U.S. Geological Survey and with the cooperation of various regional seismic networks, people who experience an earthquake can go online and share information...
USGS California Water Science Center water programs in California
Michael V. Shulters
2005, Fact Sheet 2005-3046
California is threatened by many natural hazards—fire, floods, landslides, earthquakes. The State is also threatened by longer-term problems, such as hydrologic effects of climate change, and human-induced problems, such as overuse of ground water and degradation of water quality. The threats and problems are intensified by increases in population, which...
People and water in the Assabet River basin, eastern Massachusetts
Leslie A. DeSimone
2005, Fact Sheet 2005-3034
An accounting of the inflows, outflows, and uses of water in the rapidly developing Assabet River Basin, along Interstate 495 in eastern Massachusetts, was done to quantify how people's activities alter the hydrologic system. The study identified subbasins and seasons in which outflows resulting from people's activities were relatively large...
Assessing sandhill crane roosting habitatalong the Platte River, Nebraska
