Portrayal of drainage and vegetation on topographic maps
W.J. Schneider, J. C. Goodlett
1962, Open-File Report 62-121
Accurate measurements of drainage networks are necessary for studies in many scientific disciplines, especially hydrology. To this end, topographic maps must show accurate classification as well as a consistent pattern of the stream network.A recent study in Georgia has developed two photo-interpretive keys which permit accurate drainage classification during the...
Floods at Mount Clemens, Michigan
S.W. Wiitala, Arlington D. Ash
1962, Hydrologic Atlas 59
The approximate areas inundated during the flood of April 5-6, 1947, by Clinton River, North Branch and Middle Branch of Clinton River, and Harrington Drain, in Clinton Township, Macomb County, Mich., are shown on a topographic map base to record the flood hazard in graphical form. The flood of April...
Water supply for a fish hatchery site, Clearwater Valley, Idaho
M.J. Mundorff, W. I. Travis
1962, Open-File Report 62-94
A fish hatchery proposed for the lower Clearwater River basin would require a continuous water supply of 10 to 12 cubic feet per second. Limitations on maximum and minimum temperatures and on turbidity are such that a combination surface-and ground-water supply probably would be required. Six prospective sites were examined with...
Stream composition of the conterminous United States
Francis Hays Rainwater
1962, Hydrologic Atlas 61
This atlas is comprise of three maps of the conterminous United States which show separately the prevalent dissolved-solids concentrations, prevalent chemical type, and average sediment concentration of rivers. The river-composition data shown on plates 1-3 provide a starting point for evaluating our surface-water resources on a nationwide scale, indicate regions...
Data on uranium and radium in ground water in the United States, 1954 to 1957
R. C. Scott, F. B. Barker
1962, Professional Paper 426
This report is one of a series resulting from a study by the U.S. Geological Survey to determine the occurrence and distribution of naturally radioactive substances in water. From 1954-57 uranium and radium concentrations were determined in 561 samples, mainly of ground water, having wide geologic and geographic distribution. These...
The concept of entropy in landscape evolution
Luna Bergere Leopold, Walter Basil Langbein
1962, Professional Paper 500-A
The concept of entropy is expressed in terms of probability of various states. Entropy treats of the distribution of energy. The principle is introduced that the most probable condition exists when energy in a river system is as uniformly distributed as may be permitted by physical constraints. From these general...
