Flood profile study, Squaw Creek, Linn County, Iowa
Water Resources Division, U.S. Geological Survey
1968, Open-File Report 68-302
This report is the result of a cooperative agreement between the city of Cedar Rapids and the U.S. Geological Survey that provides for the collection of hydrologic data by the Geologic Survey on small streams in and near the city. The city furnished the large-scale topographic map showing a stream...
Vertical mass transfer in open channel flow
Harvey E. Jobson
1968, Open-File Report 68-146
The vertical mass transfer coefficient and particle fall velocity were determined in an open channel shear flow. Three dispersants, dye, fine sand and medium sand, were used with each of three flow conditions. The dispersant was injected as a continuous line source across the channel and downstream concentration profiles were...
Geology of the Golden Zone mine area, Alaska
C. C. Hawley, Allen L. Clark, J. Alan Benfer
1968, Open-File Report 68-122
The Golden Zone mine area, in the upper Chulitna district, is underlain mainly by siltstone and tuff, volcanic conglomerate and breccia, and limestone. These rocks were invaded, probably in the Tertiary, by dikes and a small stock of porphyry. The ore deposits of the area are the Golden Zone breccia...
Color photographs for water resources studies
William J. Schneider
1968, Photogrammetric Engineering (34) 257-262
Air-photo interpretation is very well suited to water resources studies where limited observations of hydrologic data must be extended to regional characteristics for large areas. It is also useful in monitoring the hydrologic regimen of an area to detect possible changes. Color aerial photography is generally superior to black-and-white photography...
Geological interpretation of a Gemini photo
William R. Hemphill, Walter Danilchik
1968, Photogrammetric Engineering (34) 150-154
Study of the Gemini V photograph of the Salt Range and Potwar Plateau, West Pakistan, indicates that small-scale orbital photographs permit recognition of the regional continuity of some geologic features, particularly faults and folds that could he easily overlooked on conventional air photographs of larger scale. Some stratigraphic relationships can...
Evaporation study at Warm Springs Reservoir, Oregon
D.D. Harris
1968, Report
The mass transfer-water budget method of computing reservoir evaporation was tested on Warm Springs Reservoir, whose contents and surface area change greatly from early spring to late summer. The mass-transfer coefficient computed for the reservoir is two to three times greater than expected and results in a computed evaporation much...
Ground-water resources of Monmouth County, New Jersey
Leo A. Jablonski
1968, New Jersey Division of Water Policy and Supply Special Report 23
Monmouth County includes an area of 538 square miles in east-central New Jersey. The climate is characterized by moderate temperature, moderate humidity, and moderate precipitation. The exposed rocks in the area are chiefly sands and clays, which range in age from Late Cretaceous through Recent. The formations strike northeast-southwest and dip...
