Ground-water levels in the alluvial aquifer in eastern Arkansas, 1985
Maria Plafcan
1986, Open-File Report 86-242
This report, prepared by the U.S. Geological Survey in cooperation with the Arkansas Soil and Water Conservation Commission, the U.S. Soil Conservation Service and local Conservation Districts, contains groundwater level measurements in 485 wells tapping the Mississippi River Valley alluvial aquifer of eastern Arkansas. The measurements were made by district...
Predictive spatial modeling of narcotic crop growth patterns
Frederick A. Waltz, D. G. Moore
1986, Open-File Report 86-7
Spatial models for predicting the geographic distribution of marijuana crops have been developed and are being evaluated for use in law enforcement programs. The models are based on growing condition preferences and on psychological inferences regarding grower behavior. Experiences of local law officials were used to derive the initial model,...
Geochemical maps showing distribution and abundance of bismuth and beryllium in the nonmagnetic fraction of stream-sediment concentrates, Silver City 1 degree by 2 degrees Quadrangle, New Mexico and Arizona
Kenneth C. Watts, Jerry R. Hassemer, Carl L. Forn, David F. Siems
1986, Miscellaneous Field Studies Map 1183-H
These maps (Maps A and B) show the distribution and abundance of bismuth and beryllium in the nonmagnetic fraction of heavy-mineral concentrates from stream sediments collected in the Silver City 1o x 2o quadrangle, New Mexico and Arizona. Geochemical maps showing the distribution and abundance of nine other selected key elements...
Geochemical maps showing distribution and abundance of barium in two fractions of stream-sediment concentrates, Silver City 1 degree by 2 degrees Quadrangle, New Mexico and Arizona
Kenneth C. Watts, Jerry R. Hassemer, Carl L. Forn, David F. Siems
1986, Miscellaneous Field Studies Map 1183-K
These maps (Maps A and B) show the distribution and abundance barium in the nonmagnetic and magnetic fractions of heavy-mineral concentrates from stream sediments collected in the Silver City 1o x 2o quadrangle, New Mexico and Arizona. Geochemical maps showing the distribution and abundance of 10 other selected key elements and the mineral...
Geohydrologic data along the Salt-Gila aqueduct of the central Arizona project in Maricopa and Pinal counties, Arizona
B.L. Wallace, B.M. Wrege, H. H. Schumann
1986, Open-File Report 86-236
The U.S. Geological Survey, in cooperation with the U.S. Bureau of Reclamation, is conducting an investigation of land subsidence and earth fissures along the Salt-Gila aqueduct to identify hazard zones and to provide design data for the Central Arizona Project aqueducts. Thirty-three test holes were drilled along the Salt-Gila aqueduct...
Traveltime and dispersion in the Shenandoah River and its tributaries, Waynesboro, Virginia, to Harpers Ferry, West Virginia
K.R. Taylor, R.W. James, B.M. Helinsky
1986, Water-Resources Investigations Report 86-4065
Two traveltime and dispersion measurements using rhodamin dye were conducted on a 178-mile reach of the Shenandoah River between Waynesboro, Virginia, and Harpers Ferry, West Virginia. The flows during the two measurements were at approximately the 85% and 45% flow durations. The two sets of data were used to develop...
Selected drill-stem test data for the Upper Colorado River basin
R.W. Teller, D. T. Chafin
1986, Water-Resources Investigations Report 84-4146
Permeability data from aquifers and confining layers may be available from drill-stem tests made during the course of petroleum exploration. During the drill-stem test, the stratigraphic interval of interest is isolated in the hole by the use of packers attached to the drill string. Fluid flows into the drilling pipe...
