Hydrologic unit maps
Paul R. Seaber, F. Paul Kapinos, George L. Knapp
1987, Water Supply Paper 2294
A set of maps depicting approved boundaries of, and numerical codes for, river-basin units of the United States has been developed by the U.S . Geological Survey. These 'Hydrologic Unit Maps' are four-color maps that present information on drainage, culture, hydrography, and hydrologic boundaries and codes of (1) the 21...
Data-collection methods and data summary for the assessment of water quality in Cedar Creek, west-central Illinois
R.D. McFarlane, W.O. Freeman, A.R. Schmidt
1987, Open-File Report 87-543
A water-quality, data-collection network on a 26.2-mile reach of Cedar Creek in west-central Illinois was operated from May through December 1985 and from March through October 1986. The study reach drains a 60.8-square-mile area of predominantly agricultural land. However, the city of Galesburg contributes combined- and storm-sewer discharge to the...
Mineralogical characterization of the Shelburne Marble; a Vermont marble test stone used to study the effects of acid rain
E. S. McGee
1987, Open-File Report 87-447
The Shelburne Marble of Vermont has been used extensively in buildings and monuments and for this reason has been selected as a test stone for the National Acid Precipitation Assessment Program (NAPAP) stone exposure studies. Mineralogical characterization of fresh Shelburne Marble provides a basis for recognizing mineralogical changes that may...
