User guide for the PULSE program
A. T. Rutledge
2002, Open-File Report 2002-455
This manual describes the use of the PULSE computer program for analysis of streamflow records. The specific instructions included here and the computer files that accompany this manual require streamflow data in a format that can be obtained from U.S. Geological Survey (USGS) sites on the World Wide Web. The...
Revised Protocols for Sampling Algal, Invertebrate, and Fish Communities as Part of the National Water-Quality Assessment Program
Stephen R. Moulton II, Jonathan G. Kennen, Robert M. Goldstein, Julie A. Hambrook
2002, Open-File Report 2002-150
Algal, invertebrate, and fish communities are characterized as part of ecological studies in the U.S. Geological Survey.s National Water-Quality Assessment Program. Information from these ecological studies, together with chemical and physical data, provide an integrated assessment of water quality at local, regional, and national scales. Analysis and interpretation of water-quality...
Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-A method supplement for the determination of Fipronil and degradates in water by gas chromatography/mass spectrometry
James F. Madsen, Mark W. Sandstrom, Steven D. Zaugg
2002, Open-File Report 2002-462
A method for the isolation and detemrination of fipronil and four of its degradates has been developed. This method adapts an analytical method created by the U.S. Geological Survey National Water Quality Laboratory in 1995 for the determination of a broad range of high-use pesticides typically found in filtered...
A bibliography of terrain modeling (geomorphometry), the quantitative representation of topography: Supplement 4.0
Richard J. Pike
2002, Open-File Report 2002-465
Terrain modeling, the practice of ground-surface quantification, is an amalgam of Earth science, mathematics, engineering, and computer science. The discipline is known variously as geomorphometry (or simply morphometry), terrain analysis, and quantitative geomorphology. It continues to grow through myriad applications to hydrology, geohazards mapping, tectonics, sea-floor and planetary exploration, and...

Water-Resources Investigations in Wisconsin, 2002
K. A. Hueschen (compiler), S.Z. Jones, J. A. Fuller
2002, Open-File Report 2002-300
The statewide average precipitation of 34.83 inches for the 2001 water year was 3.15 inches greater than the normal annual precipitation of 31.68 inches for water years 1961–90. Average precipitation values affecting streamflow conditions ranged from 92 percent in northeast Wisconsin to 122 percent in southwest Wisconsin with a statewide...
