Late Cenozoic stratigraphy and structure of the western margin of the central San Joaquin Valley, California
William R. Lettis
1982, Open-File Report 82-526
Late Cenozoic Stratigraphy Late Cenozoic deposits in the west-central San Joaquin Valley and adjacent foothills of the Diablo Range consist mainly of unconsolidated, poorly-sorted to well-sorted gravel, sand, silt and clay derived primarily from the Diablo Range and secondarily from the Sierra Nevada. Sedimentary structures, such as channeled contacts, laminated...
Geohydrology of principal aquifers in the Republican River basin, Kansas
L. E. Dunlap
1982, Open-File Report 82-79
Principal aquifers in the Republican River basin in Kansas are unconsolidated alluvial deposits. One such aquifer is formed by the Ogallala Formation of Miocene age which covers most of the western part of the area. Because saturated thickness of the aquifer decrease northeastward, maximum yields to irrigation wells decrease in...
Digital classification of Landsat data for vegetation and land-cover mapping in the Blackfoot River watershed, southeastern Idaho
L. R. Pettinger
1982, Professional Paper 1219
This paper documents the procedures, results, and final products of a digital analysis of Landsat data used to produce a vegetation and landcover map of the Blackfoot River watershed in southeastern Idaho. Resource classes were identified at two levels of detail: generalized Level I classes (for example, forest land and...
Effects of flooding upon woody vegetation along parts of the Potomac River flood plain
T.M. Yanosky
1982, Professional Paper 1206
A two-part study along the Potomac River flood plain near Washington, D.C., was undertaken to investigate the effects of flooding upon woody vegetation. Floods abrade bark, damage branches and canopies, and often uproot trees. The first study was of vegetation in five monumented flood-plain plots which differed in the frequency...
Geochemical survey of the Ramseys Draft Addition, Augusta and Highland counties, Virginia
Frank G. Lesure
1982, Miscellaneous Field Studies Map 1369-B
The U.S. Geological Survey (USGS) made a reconnaissance geochemical survey of the Ramseys Draft Addition (fig.1) to test for indistinct or unexposed mineral deposits that might be recognized by their geochemical halos.  Thirty-three stream-sediment, two soil, and 22 rock samples were collected from the addition during the earlier study of...
Water resources data for Florida, water year 1981; Volume 1. Northeast Florida
Water Resources Division, U.S. Geological Survey
1982, Water Data Report FL-81-1
Water resources data for the 1981 water year for northeast Florida consist of records of stage, discharge, and water quality of streams; elevation and water quality of lakes and reservoirs; water levels and water quality of wells; and discharge and water quality of springs. Additional water data were collected at...
Map showing how the potentiometric surface of the Magothy Aquifer of August 1980 differed from the potentiometric surface of September 1977, in southern Maryland
Frederick K. Mack Jr., J. C. Wheeler, Stephen E. Curtin
1982, Open-File Report 81-631
The map is based on the differences between two sets of water-level measurements made in 65 observation wells. One set was made in 1977, a relatively dry year, and the other set was made in 1980, another relatively dry year. The map shows that the potentiometric surface was higher in...
Locality map for scintillometer and analytical data collected in 1981, Ugashik and Karluk quadrangles, Alaska
Robert L. Detterman, W.H. Allaway Jr., G.W. Day, D.M. Hopkins, R. M. O’Leary, Edward Svec
1982, Open-File Report 82-53
Scintillometer data were collected routinely in 1981 as part of the field investigations in the Ugashik and Karluk quadrangles. The instrument used was a Geometrics Model GR-101A, mounted in the helicopter. The data, in counts per second (cps), were obtained at most of the sites by the helicopter pilot (Svec)...
Percentage change in saturated thickness of the High Plains Aquifer, west-central Kansas, 1950 to average 1980-82
Marilyn E. Pabst
1982, Open-File Report 82-1010
A statistical technique, called kriging, was programmed for a computer to interpolate hydrologic data based on a network of 296 measured values in west-central Kansas and eastern Colorado. The computer program generated estimated values of selected hydrologic data at the center of each 1-mile section in the Western Kansas Groundwater...
