Effects of urban runoff and wastewater effluent on Wilsons Creek and James River near Springfield, Missouri
Wayne R. Berkas
1980, Water-Resources Investigations Report 80-27
Statistical analysis on water-quality parameters from James River upstream and downstream from the confluence of Wilsons Creek shows a significant difference for all parameters except temperature and dissolved silica at the 0.05 probability level. Regression analysis shows correlation for discharge with dissolved sodium, dissolved chloride, and dissolved potassium, and for...
Technique for estimating magnitude and frequency of floods in Maryland
David H. Carpenter
1980, Open-File Report 80-1016
A method is presented for estimating flood magnitudes for natural drainage basins without urban development or regulated flow. The method was developed by multiple-regression techniques and applies to floods with recurrence intervals from 2 to 100 years.The State is divided into three regions, and sets of equations for calculating peak...
Summaries of data on and lists of references to metallic and selected nonmetallic mineral deposits in fifteen quadrangles in southwestern and west-central Alaska
Edward Huntington Cobb
1980, Open-File Report 80-909
These summaries of data on metallic and selected nonmetallic mineral occurrences and lists of selected references to them in Geological Survey, U.S. Bureau of Mines, and State of Alaska Division of Geological and Geophysical Surveys (and predecessor State and Territorial agencies) reports and maps released before Jan. 1, 1980, and...
Hydrologic data from upper Grange Hall Creek basin, Northglenn, Adams County, Colorado
Dennis C. Hall, A.C. Duncan
1980, Open-File Report 80-578
Hydrologic data collected during 1977-79 as part of a water-resources investigation of storm runoff in Upper Grange Hall Creek basin, Adams County, Colo., are presented in this report. Data presented in tabular form consist of: (1) Estimated daily precipitation at one site (April through October, 1978 and 1979); (2) mean...
The Quality of Water Discharging From the New River and Clear Fork Basins, Tennessee
R. S. Parker, W. P. Carey
1980, Water-Resources Investigations Report 80-37
The quality of water discharging from a strip-mined basin and a relatively unmined basin on the Cumberland Plateau in Tennessee are examined and compared. The chemical and aesthetic quality of these waters will directly affect the chemical and aesthetic quality of the water flowing through a proposed national river and...
Minisparker profiles from Jeffreys Ledge and adjacent areas in the western Gulf of Maine
Diane M. Eskenasy, Norman G. Bailey
1980, Open-File Report 80-320
A total of 250 kilometers of single-channel seismic-reflection data (28 minisparker profiles) were collected in the coastal waters of Massachusetts, north of and immediately south of Cape Ann, and on the western flank of Jeffreys Ledge, western Gulf of Maine, during the September 1978 cruise of the R/V ASTERIAS. The...
Quantitative analysis versus semiquantitative optical emission spectrographic analysis of chromium, nickel, zinc, vanadium, and molybdenum in organic-rich Paleozoic marine strata, Western United States
George A. Desborough, F. G. Poole, Edwin K. Maughan, H.L. Groves, Gregory N. Green
1980, Open-File Report 80-1271
Comparison of analytical results between the quantitative method and the semiquantitative six-step optical-emission spectrographic method commonly shows significantly lower values for the semiquantitative method. The lower values are most obvious for splits from the same samples of fine-grained organic-rich rocks where the concentrations of the metals chromium, nickel, zinc, vanadium,...
