Whole-rock chemical composition of some samples from two drill hole cores in the Capps coal field, Beluga coal area, south-central Alaska
T. K. Hinkley, K. S. Smith, J. L. Peard, M.L. Tompkins
1982, Open-File Report 82-672
Whole-rock chemical analysis was done on samples from drill cores of rocks lying atop and between coal beds in the Beluga coal area, south-central Alaska. The samples were classified as sandstone, siltstone or claystone at time of hand specimen description. Chemical data were compared to those from corresponding rocks from...
Floods of October 1977 in southern Arizona and March 1978 in central Arizona
B. N. Aldridge, J.H. Eychaner
1982, Open-File Report 82-687
Major floods occurred in October 1977 and March 1978 in Arizona. As much as 14 inches of rain fell during October 6-9, 1977, over the mountains of southern Arizona and northern Mexico and caused the highest discharge since at least 1892 on the Santa Cruz River upstream from Tucson. The...
Hydrologic data-verification management program plan
C.W. Alexander
1982, Open-File Report 82-374
Data verification refers to the performance of quality control on hydrologic data that have been retrieved from the field and are being prepared for dissemination to water-data users. Water-data users now have access to computerized data files containing unpublished, unverified hydrologic data. Therefore, it is necessary to develop techniques and...
Distributed routing rainfall-runoff model; version II
W.M. Alley, P. E. Smith
1982, Open-File Report 82-344
A computer program of a watershed model for routing storm runoff through a branched system of pipes and (or) natural channels using rainfall as input is described. The model provides detailed simulation of storm-runoff periods selected by the user and a daily soil-moisture accounting between storms. A drainage basin is...
Multi-event urban runoff quality model
W.M. Alley, P. E. Smith
1982, Open-File Report 82-764
A computer model is presented for simulating the quality of surface runoff from urban watersheds. The model can simulate impervious area, pervious area, and precipitation contributions to runoff quality as well as the effects of street sweeping and (or) detention storage. Within-storm variations of runoff quality are simulated for user-specified...
Effects of processed oil shale on the element content of Atriplex cancescens
B.M. Anderson
1982, Open-File Report 82-1051
Samples of four-wing saltbush were collected from the Colorado State University Intensive Oil Shale Revegetation Study Site test plots in the Piceance basin, Colorado. The test plots were constructed to evaluate the effects of processed oil shale geochemistry on plant growth using various thicknesses of soil cover over the processed...
Water quality of Lake Granbury, north-central Texas
Freeman L. Andrews, Jeffrey L. Strause
1982, Open-File Report 82-676
During water years 1970-79, the concentrations of the major dissolved constituents in Lake Granbury on the Brazos River in north-central Texas averaged about 1,800 milligrams per liter of dissolved solids, 700 milligrams per liter of chloride, and 350 milligrams per liter of sulfate. The water was generally very hard (hardness...
Selected hydrologic data for northern Utah Valley, Utah, 1935-82
Cynthia L. Appel, David W. Clark, Paul E. Fairbanks
1982, Open-File Report 82-1023
This report contains hydrologic data collected in northern Utah Valley from 1935 to 1982. Northern Utah Valley is approximately the northern half of an alluvial-filled basin partly occupied by Utah Lake in north-central Utah. The report area is bounded by the Wasatch Range on the east, the Lake Mountains on...
