Geology and ground water in Door County, Wisconsin, with emphasis on contamination potential in the Silurian dolomite
Marvin G. Sherrill
1977, Open-File Report 77-61
Door County, a recreational and fruit-growing area bordering Lake Michigan in northeastern Wisconsin, has had a long history of ground-water contamination from surface and near-surface sources. Contamination is most severe in late summer when fruit-canning operations and the influx of tourists create additional wastes. Silurian dolomite is the upper bedrock...
A compilation of data from the July, 1976 Oroville, California seismic-refraction experiment
Mary Ann Spieth, David P. Hill
1977, Open-File Report 77-881
The August 1, 1975, Oroville, California, earthquake (Mb = 5.7) and its aftershocks focused considerable interest on current tectonic processes operating in the western foothills of the Sierra Nevada range. As part of an intensive study of this earthquake sequence, the United States Geological Survey with support from the California...
SIPB: a seismic refraction inverse modeling program for batch computer systems
James Henry Scott
1977, Open-File Report 77-366
SIPB is an interactive Fortran computer program that was developed for use with a timeshare computer system with program control information submitted from a remote terminal, and output data displayed on the terminal or printed on a line printer. The program is an upgraded version of FSIPI (Scott, Tibbetts, and...
Development of water facilities in the Santa Ana River Basin, California, 1810-1968: a compilation of historical notes derived from many sources describing ditch and canal companies, diversions, and water rights
M.B. Scott
1977, Open-File Report 77-398
This report traces by text, maps, and photographs, the development of the water supply in the Santa Ana River basin from its beginning in 1810 or 1811 to 1968. The value of the report lies in the fact that interpretation of the hydrologic systems in the basin requires knowledge of...
Computer program for the calculation of grain size statistics by the method of moments
Michael B. Sawyer
1977, Open-File Report 77-580
A computer program is presented for a Hewlett-Packard Model 9830A desk-top calculator (1) which calculates statistics using weight or point count data from a grain-size analysis. The program uses the method of moments in contrast to the more commonly used but less inclusive graphic method of Folk and Ward (1957). The...
Simulated changes in ground-water levels resulting from proposed phosphate mining, west-central Florida; preliminary results
William Edward Wilson
1977, Open-File Report 77-882
A digital model of two-dimensional ground-water flow was used to simulate projected changes in the Floridan aquifer potentiometric surface in 1985 and 2000, resulting from proposed ground-water developments by the phosphate mining industry in west-central Florida. The .model was calibrated under steady-state conditions to simulate the September 1975 potentiometric surface....
Well records, water-level measurements, logs of test holes, and chemical analyses of ground water in the Cache River alluvial aquifer-stream system, northeast Arkansas, 1946-76
Paul W. Westerfield
1977, Open-File Report 77-402
Most of the ground-water data for the Cache River alluvial aquifer-stream system in northeast Arkansas were collected between March 1973 and April 1976, but some were collected as early as April 1946. The data includes records of 363 wells and test holes, water-level measurements of 295 wells, logs of 32...
