Water security-National and global issues
James A. Tindall, Andrew A. Campbell
2010, Fact Sheet 2010-3106
Potable or clean freshwater availability is crucial to life and economic, environmental, and social systems. The amount of freshwater is finite and makes up approximately 2.5 percent of all water on the Earth. Freshwater supplies are small and randomly distributed, so water resources can become points of conflict. Freshwater availability...

Cyclic ground tilt associated with the 2004–2008 eruption of Mount St. Helens
K. Anderson, Michael Lisowski, P. Segall
2010, Journal of Geophysical Research B: Solid Earth (115)
The long‐term behavior of the 2004–2008 effusive eruption of Mount St. Helens was characterized by a gradual decline in the rates of seismicity, dome growth, and broad‐scale ground deformation, but shallow near‐periodic “drumbeat” earthquakes over timescales of minutes indicated episodic short‐term behavior. In part to better characterize this behavior and...

Occurrence of phosphorus in groundwater and surface water of northwestern Mississippi
Heather L. Welch, James A. Kingsbury, Richard H. Coupe
2010, Conference Paper, Proceedings from the 2010 Mississippi water resources conference
Previous localized studies of groundwater samples from the Mississippi River Valley alluvial (MRVA) aquifer have demonstrated that dissolved phosphorus concentrations in the aquifer are much higher than the national background concentration of 0.03 milligram per liter (mg/L) found in 400 shallow wells across the country. Forty-six wells screened in the...

A multibeam echo sounder mapping system was used to obtain channel-bed elevations...
Quantity and sources of base flow in the San Pedro River near Tombstone, Arizona
Jeffrey R. Kennedy, Bruce Gungle
2010, Scientific Investigations Report 2010-5200
Base flow in the upper San Pedro River at the gaging station (USGS station 09471550) near Tombstone, Arizona, is an important factor in the long-term sustainability of the river's riparian ecosystem. Most base flow occurs during the non-summer months (typically, from November to May), because evapotranspiration (ET) is greater...

Summary of Bed-Sediment Measurements Along the Platte River, Nebraska, 1931-2009
P.J. Kinzel, J.T. Runge
2010, Fact Sheet 2010-3087
Rivers are conduits for water and sediment supplied from upstream sources. The sizes of the sediments that a river bed consists of typically decrease in a downstream direction because of natural sorting. However, other factors can affect the caliber of bed sediment including changes in upstream water-resource development, land use,...
