Stephen E. Curtin, David C. Andreasen, Judith C. Wheeler
2002, Open-File Report 2002-447
This report presents a map showing the change in the potentiometric surface of the Upper Patapsco aquifer in the Upper Patapsco Formation of Cretaceous age in Southern Maryland for September 1990 and September 2001. The map, based on water level measurements in 35 wells, shows that during the 11-year period,...
An Intelligent Systems Approach to Automated Object Recognition: A Preliminary Study
Brian G. Maddox, Casey L. Swadley
2002, Open-File Report 2002-461
Attempts at fully automated object recognition systems have met with varying levels of success over the years. However, none of the systems have achieved high enough accuracy rates to be run unattended. One of the reasons for this may be that they are designed from the computer's point of view...
Selected effects of the Conservation Reserve Program on program participants: A report to survey respondents
Mark W. Vandever, Arthur W. Allen, Natalie R. Sexton
2002, Open-File Report 2002-476
The Conservation Reserve Program (CRP) established under the 1985 Food Security Act was initially designed to provide the agricultural community economic assistance while protecting highly erodible cropland. Many of the environmental benefits to soil, water, and wildlife resources have been documented (Dunn and others, 1993; Ryan and others, 1998; Flather...
Water-quality data for pharmaceuticals, hormones, and other organic wastewater contaminants in U.S. streams, 1999-2000
Kimberlee K. Barnes, Dana W. Kolpin, Michael T. Meyer, E. Michael Thurman, Edward T. Furlong, Steven D. Zaugg, Larry B. Barber
2002, Open-File Report 2002-94
Water-quality data collected during 1999 and 2000 as part of the first nationwide reconnaissance of the occurrence of pharmaceuticals, hormones, and other organic wastewater contaminants (OWCs) are presented in this report.
