Measurement of mixing characteristics of the Missouri River between Sioux City, Iowa, and Plattsmouth, Nebraska
Nobuhiro Yotsukura, Hugo B. Fischer, William W. Sayre
1970, Water Supply Paper 1899-G
Measurements of longitudinal dispersion, transverse mixing, channel geometry, and transverse velocity distribution were made in the Missouri River at a flow of about 33,000 cubic feet per second. The results show that the longitudinal dispersion coefficient for the 141-mile reach from Sioux City, Iowa, to Plattsmouth, Nebr., is about 16,000...
Feasibility of surveying pesticide coverage with airborne fluorometer
George Eimert Stoertz, William R. Hemphill
1970, Open-File Report 70-315
Response of a Fraunhofer line discriminator (FLD) to varying distributions of granulated corncobs stained with varying concentrations of Rhodamine WT dye was tested on the ground and from an H-19 helicopter. By design the instrument detected fluorescence specifically at the sodium D2 Fraunhofer line (5890 angstroms). The granules are used...
Analyses of rock and stream-sediment samples from the Sumdum C-4 Quadrangle, Alaska
Allen L. Clark, David A. Brew, Donald A. Grybeck, Raymond Wehr
1970, Open-File Report 70-76
Analytical data for 31 rock and 33 stream-sediment samples from the Sumdum C-4 , 1:63,360 scale quadrangle are presented in this report, together with a statistical treatment of the data. The samples were collected in 1969 as part of the Heavy Metals Program of the U.S. Geological Survey.The most comprehensive...
Bibliography of reports resulting from U.S. Geological Survey participation in the United States Technical Assistance Program: Supplement for 1968-1969
Wenonah E. Bergquist
1970, Open-File Report 70-26
U. S. Geological Survey Bulletin 1263, by Jo Ann Heath and Nancy B. Tabacchi lists the reports that resulted from a wide variety of geologic and hydrologic investigations, .and institutional development programs undertaken by the U. S. Geological Survey and counterpart agencies in 51 foreign countries from 1940-67. This supplementary...
Accoustical survey of Massachusetts and Cape Cod Bays, western Gulf of Maine
Brian E. Tucholke, Robert N. Oldale, C. D. Hollister
1970, Open-File Report 70-331
The accompanying map shows the amount of acoustic penetration achieved in the sediments of the western Gulf of Maine using a 3.5 kHz echo sounding system and illustrates the pronounced control of topography on sediment distribution. Little or no sub-bottom penetration was observed in areas of sand and gravel on...
Geology and mineral evaluation of the Wadi Bidah district, southern Hijaz quadrangle, Kingdom of Saudi Arabia
Robert L. Earhart, Mustafa M. Mawad
1970, Open-File Report 70-116
The Wadi Bidah district in southwest Saudi Arabia contains several ancient mines and mineral-prospects. The Precambian rocks of the district are steeply dipping and highly folded and faulted. They are divided into three major units: (1) older metavolcanic rocks, (2) metasedimentary rocks, and (3) younger metavolcanic rocks. Massive sulfide-type deposits...
