Flood characteristics of urban watersheds in the United States
Vernon B. Sauer, W.O. Thomas Jr., V.A. Stricker, K. V. Wilson
1983, Water Supply Paper 2207
A nationwide study of flood magnitude and frequency in urban areas was made for the purpose of reviewing available literature, compiling an urban flood data base, and developing methods of estimating urban floodflow characteristics in ungaged areas. The literature review contains synopses of 128 recent publications related to urban floodflow....
Use of flumes in measuring discharge
F. A. Kilpatrick, V.R. Schneider
1983, Techniques of Water-Resources Investigations 03-A14
Flumes for measuring discharge are usually of two general groups-critical-flow flumes and supercritical-flow flumes. In this chapter, the underlying design principles for each group are discussed; the most commonly used flumes are described and their discharge ratings presented. There is also discussion of considerations in choosing and fitting the appropriate...
Ground-water quality in the western Snake River basin, Swan Falls to Glenns Ferry, Idaho
D. J. Parliman
1983, Water-Resources Investigations Report 83-4062
Water-quality data were collected from 92 wells in the western Snake River basin, Swan Falls to Glenns Ferry, Idaho. Current data were compiled with pre-1980 data from 116 wells to define water-quality conditions in major aquifers. Factors affecting water quality are composition of aquifer materials, water temperature, and source of...
Comparative physiographic diagrams of Mount St. Helens, Washington, and Crater Lake, Oregon
Tau Rho Alpha, Jim M. Morley
1983, Miscellaneous Field Studies Map 1403
These physiographic diagrams provide a visual comparison of two Cascade Range volcanoes which have had their tops destroyed in different ways -- Mount St. Helens in 1980, Mount Mazama (whose site is now occupied by Crater Lake) about 6,800 years ago. Both volcanoes are viewed from the north from 30...
Initial assessment of time of travel and mixing through Gulf Island Pond and the lower Androscoggin River, Maine
G.W. Parker, G.S. Hunt
1983, Water-Resources Investigations Report 83-4020
Flow-stratification patterns were observed in Gulf Island Pond during time-of-travel studies in May and August 1980. The stratification patterns in this 70 million cubic-meter impoundment were due to a temperature differences between inflowing water and reservoir water. Separation was observed at temperature differences of 0.5 degrees C in May 1980...
Quality-assurance data for routine water analysis in the laboratories of the US Geological Survey for water-year 1982
Dale B. Peart, Nancy Thomas
1983, Water-Resources Investigations Report 83-4264
The U.S. Geological Survey maintains a quality-assurance program based on the analysis of reference samples for its two water-analysis laboratories located in Atlanta, Georgia, and Denver, Colorado. Reference samples containing inorganic constituents are prepared at the U.S. Geological Survey 's Ocala , Florida, office and disguised as routine samples, and...
Meteorological, water-temperature, and discharge data for the Mattole River basin, Humboldt County, California
R.D. Noble, Alan P. Jackman
1983, Water-Resources Investigations Report 78-81
To overcome a major difficulty in the testing of the validity of river-temperature models - the lack of adequate precise synoptic data for an entire river basin - synoptic meteorologic, water-temperature, and discharge data were obtained in the Mattole River Basin in northern California during the period June 10 through...
Quality-assurance data for routine water analysis in the laboratories of the US Geological Survey; 1981 annual report
D.B. Peart, Nancy Thomas
1983, Water-Resources Investigations Report 83-4090
The U.S. Geological Survey maintains a quality-assurance program based on the analysis of reference samples for its two water-analysis laboratories located in Atlanta, Georgia and Denver, Colorado. Reference containing inorganic constituents are prepared at the U.S. Geological Survey 's Ocala, Florida, office and disguised as routine samples, and sent daily...
Hydrology of the Little Androscoggin River Valley aquifer, Oxford County, Maine
D. J. Morrissey
1983, Water-Resources Investigations Report 83-4018
The Little Androscoggin River valley aquifer, a 15-square-mile sand and gravel valley-fill aquifer in southwestern Maine, is the source of water for the towns of Norway, Oxford, and South Paris. Estimated inflows to the aquifer during the 1981 water year were 16.4 cubic feet per second from precipitation directly on...
Hydrogeology of parts of the Central Platte and Lower Loup Natural Resources Districts, Nebraska
J. M. Peckenpaugh, J. T. Dugan
1983, Water-Resources Investigations Report 83-4219
Water-level declines of at least 15 feet have occurred in this heavily irrigated area of central Nebraska since the 1930's, and potential for additonal declines is high. To test the effects of additional irrigation development on water levels and streamflow , computer programs were developed that represent the surface-water system,...
Mineral resource assessment of the Iron River 1° x 2° quadrangle, Michigan and Wisconsin
William F. Cannon
1983, Circular 887
The Iron River 1? x 2? quadrangle contains identified resources of copper and iron. Copper-rich shale beds in the north part of the quadrangle contain 12.2 billion pounds (5.5 billion kilograms) of copper in well-studied deposits including 9.2 billion pounds (4.2 billion kilograms) that are economically minable by 1980 standards....
Geophysical investigations of the Umm ar Rummf copper prospect, Al Qunfudhah Quadrangle, Kingdom of Saudi Arabia
Hamdy S. Sadek, H. Richard Blank
1983, Open-File Report 83-298
The Umm ar Rummf copper prospect, located about 30 km east of Al Qunfudhah, Kingdom of Saudi Arabia, consists of zones of malachite disseminations and fracture fillings in outcrops of north-trending impure quartzite of the Bahah group. Systematic Crone electromagnetic and self-potential surveys indicate that weakly conductive tabular bodies having...
Environmental-stratigraphic cross sections of the Cretaceous Fox Hills Sandstone and Hell Creek Formation and Paleocene Fort Union Formation, Richland and Roosevelt Counties, Montana
R. M. Flores, C.L. Lepp
1983, Miscellaneous Field Studies Map 1554
This study was conducted to determine the stratigraphic, lithofacies, and deopsitional relationships of the Cretaceous Fox Hills Sandstone and Hell Creek Formation and The Paleocene Fort Union Formation. These relationships, shown in sections A-A', B-B', C-C', and D-D', we established form nearly continuous exposures in the Missouri River valley in...
Description of slides showing aeromagnetic and gravity data for regional mineral exploration in Colorado, New Mexico, and Arizona
Douglas P. Klein
1983, Open-File Report 83-703
Examples of aeromagnetic and gravity data over 1? x 2? areas are presented for regions near the Cripple Creek mining area, Colorado, and the Lordsburg-Tyrone-Silver City mining areas, southern New Mexico and Arizona. These data indicate broad crustal structures and compositional variations that are marked by magnetization and density contrasts....
