Evaporation from Lake Michie, North Carolina 1961-71
W.L. Yonts, G. L. Giese, E. F. Hubbard
1973, Water-Resources Investigations Report 73-38
The Geological Survey, in cooperation with the city of Durham, N. C., collected evaporation data at Lake Michie, Durham's 480-acre water-supply reservoir, for 10 consecutive years from September 1961 to September 1971. Wind speed, air temperature, and water temperature-collected continuously-were used in conjunction with water-budget data to calibrate the semi-empirical...
Floods in the Iowa River basin upstream from Coralville Lake, Iowa
Albert J. Heinitz
1973, Open-File Report 73-106
Flood information is reported for 207 miles of the main stem, 23 miles on the West Branch, and 23 miles on the East Branch, of the Iowa River. The information will be of use to those concerned with the design of bridges and other structures and the conduct of various...
Floods in the Rock River basin, Iowa
Albert J. Heinitz
1973, Open-File Report 74-1047
This report contains flood information for the Rock River basin in Iowa, it updates and supersedes the 1967 report "Floods in Rock River basin, Iowa" by P. J. Carpenter. The occurrence of an outstanding flood in 1969 and the acquisition of additional flood data in the basin prompted the preparation of...
Velocity and depth measurements for use in computation of reaeration coefficients
John S. Zogorski, Peter W. Anderson, Owen O. Williams
1973, Open-File Report 73-369
Empirical computation of reaeration coefficients generally requires knowledge of mean velocity and mean depth of a stream. A practical method for obtaining this knowledge is described herein. The method involves time-of-travel, streamflow, and cross-sectional measurements, the development of discharge-velocity curves, streamflow profiles, and the computation of cross-sectional areas. Values for...
A national study of the streamflow data-collection program
Manuel A. Benson, Rolland William Carter
1973, Water Supply Paper 2028
The streamflow data program of the U.S. Geological Survey was evaluated in a nationwide study during 1970. The principal elements of the study were (1) establishing the objectives and goals of the program, (2) analyzing all available data to determine which of the goals have already been met, (3) considering...
Valley fill in the Roswell-Artesia area, New Mexico
Forest P. Lyford
1973, Open-File Report 73-163
Drill samples from 225 water and oil wells in an area 70 miles long and 20 miles wide in the Roswell-Artesia area, southeastern New Mexico were examined. A thickness map and a saturated thickness map of the valley-fill sediments were constructed. Maximum depth of valley fill is about 300 feet...
Review of wastewater problems and wastewater-management planning in the San Francisco Bay region, California
Walter G. Hines
1973, Open-File Report 73-112
The San Francisco Bay region has suffered adverse environmental effects related to the discharge of municipal-, industrial-, and agricultural- wastewater and storm-water runoff. Specific pollutional properties of theses discharges are not well understood in all cases although the toxic materials and aquatic-plant nutrients (biostimulants) found in municipal and industrial...
Salt structure and sediment thickness, Texas-Louisiana continental slope, northwestern Gulf of Mexico
Raymond G. Martin Jr.
1973, Open-File Report 73-179
The objectives of this study were to determine the general configuration of the salt surface beneath the Texas-Louisiana continental slope and to isopach the Mesozoic-Cenozoic sedimentary section lying upon it. The structure contour map discloses that the entire slope province between the shelf edge and Sigsbee Escarpment is underlain by salt...
