In 1999, the Methods Research and Development Program of the U.S. Geological Survey National Water Quality Laboratory began the process of developing a method designed to identify and quantify human-health pharmaceuticals in four filtered water-sample types: reagent water, ground water, surface water minimally affected by human contributions, and surface...
Simplified Surface Energy Balance (SSEB) approach for estimating actual ET: An evaluation with lysimeter data
Prasanna H. Gowda, Gabriel B. Senay, Paul D. Colaizzi, Terry A. Howell
2008, Conference Paper
Evapotranspiration (ET) is an essential component of the water balance and a major consumptive use of irrigation water and precipitation on cropland. Numerous energy balance (EB) algorithms have been developed to make use of remote sensing data to estimate ET regionally. However, a review of different ET mapping algorithms shows...

Update to the Ground-Water Withdrawals Database for the Death Valley Regional Ground-Water Flow System, Nevada and California, 1913-2003
Michael T. Moreo, Leigh Justet
2008, Data Series 340
Ground-water withdrawal estimates from 1913 through 2003 for the Death Valley regional ground-water flow system are compiled in an electronic database to support a regional, three-dimensional, transient ground-water flow model. This database updates a previously published database that compiled estimates of ground-water withdrawals for 1913-1998. The same methodology is used...
Using the U.S. Geological Survey National Water Quality Laboratory LT-MDL to Evaluate and Analyze Data
Bernadine A. Bonn
2008, Open-File Report 2008-1227
A long-term method detection level (LT-MDL) and laboratory reporting level (LRL) are used by the U.S. Geological Survey?s National Water Quality Laboratory (NWQL) when reporting results from most chemical analyses of water samples. Changing to this method provided data users with additional information about their data and often resulted in...

Mapping of Florida's coastal and marine resources: Setting priorities workshop
Lisa Robbins, Steven Wolfe, Ellen Raabe
2008, Open-File Report 2008-1157
The importance of mapping habitats and bioregions as a means to improve resource management has become increasingly clear. Large areas of the waters surrounding Florida are unmapped or incompletely mapped, possibly hindering proper management and good decisionmaking. Mapping of these ecosystems is among the top priorities identified by...
Bed-material entrainment and associated transportation infrastructure problems in streams of the Edwards Plateau, central Texas
Franklin T. Heitmuller, William H. Asquith
2008, Fact Sheet 2008-3047
The Texas Department of Transportation commonly builds and maintains low-water crossings (LWCs) over streams in the Edwards Plateau in Central Texas. LWCs are low-height structures, typically constructed of concrete and asphalt, that provide acceptable passage over seasonal rivers or streams with relatively low normal-depth flow. They are designed to accommodate...
