Water-Quality Assessment of the San Joaquin-Tulare Basins: Entering a new decade
Jo Ann M. Gronberg, Charles R. Kratzer, Karen R. Burow, Joseph L. Domagalski, Steven P. Phillips
2004, Fact Sheet 2004-3012
In 1991, the National Water-Quality Assessment (NAWQA) Program of the U.S. Geological Survey began to address the need for consistent and scientifically sound information for managing the Nation's water resources. The long-term goals of this program are to assess the status of the quality of freshwater streams and aquifers, to...
Mapping a flood before it happens
Joseph L. Jones
2004, Fact Sheet 2004-3060
What's missing from flood forecasts? Maps—The only maps generally available today are maps used for planning. They are maps of theoretical floods, not maps of flooding forecast for an approaching storm. The U.S. Geological Survey (USGS) and the National Weather Service (NWS) have developed a way to bring flood...
Sources of water to the Rio Grande upstream from San Marcial, New Mexico
Stephanie J. Moore, Scott K. Anderholm, Tara Williams-Sether, John M. Stomp
2004, Fact Sheet 110-03
The Rio Grande watershed is a complex hydrologic system that includes numerous tributaries, inflow from transmountain diversions, irrigation diversions, agricultural return lows, reservoirs, and ground-water inflows and outflows. Many people depend on and are affected by the Rio Grande, which is the largest river of the surface-water system draining the...
The value of long-term monitoring in the development of ground-water-flow models
Daniel T. Feinstein, David J. Hart, James T. Krohelski
2004, Fact Sheet 116-03
As environmental issues have come to the forefront of public concern, so has the awareness of the importance of ground water in the overall water cycle and as a source of the Nation’s drinking water. Heightened interest has spawned a host of scientific enterprises (Taylor and Alley, 2001). Some...
SAM 2.1—A computer program for plotting and formatting surveying data for estimating peak discharges by the slope-area method
J.E. Hortness
2004, Fact Sheet 2004-3028
The U.S. Geological Survey (USGS) measures discharge in streams using several methods. However, measurement of peak discharges is often impossible or impractical due to difficult access, inherent danger of making measurements during flood events, and timing often associated with flood events. Thus, many peak discharge values often are calculated after...
