Velocity profile, water-surface slope, and bed-material size for selected streams in Colorado
J.P. Marchand, R.D. Jarrett, L.L. Jones
1984, Open-File Report 84-733
Existing methods for determining the mean velocity in a vertical sampling section do not address the conditions present in high-gradient, shallow-depth streams common to mountainous regions such as Colorado. The report presents velocity-profile data that were collected for 11 streamflow-gaging stations in Colorado using both a standard Price type AA...
Measurement of discharge using tracers
Frederick A. Kilpatrick, Ernest D. Cobb
1984, Open-File Report 84-136
The development of fluorescent dyes and fluorometers that can measure these dyes at very low concentrations has made dye-dilution methods practical for measuring discharge. These methods are particularly useful for determining discharge under certain flow conditions that are unfavorable for current meter measurements. These include small streams, canals, and pipes...
Hydrogeologic data from a test well at Kathryn Abbey Hanna Park, City of Jacksonville, Florida
D.P. Brown, R.A. Johnson, J.S. Baker
1984, Open-File Report 84-143
A 2,026-foot test well was drilled at Hanna Park, City of Jacksonville, Florida, to obtain hydrogeologic data. Drill cuttings and water samples were collected, and water-level measurements and lithologic and geophysical logs were made. The well is constructed with 6-inch diameter casing from land surface to a depth of 1,892...
Hydrologic data for urban studies in the Austin, Texas, metropolitan area, 1982
R.M. Slade, J.E. Veenhuis, M.E. Dorsey, S.L. Stewart, L.M. Ruiz
1984, Open-File Report 84-61
Hydrologic investigations of urban watersheds in Texas were begun by the U.S. Geological Survey in 1954. Studies are now in progress in Austin, and Houston. Studies have been completed in the Dallas, Fort Worth, and San Antonio areas. The Geological Survey, in cooperation with the Texas Department of Water Reources, began...
