Progress in the application of landform analysis in studies of semiarid erosion
Stanley Alfred Schumm, R. F. Hadley
1961, Circular 437
The analysis of topographic and hydrologic data gathered during studies of erosion in semiarid areas of Western United States show the following relation: (a) Mean annual sediment yield from small drainage basins is related to a ratio of basin relief to length; (b) mean annual runoff from small drainage basins...
Availability of ground water in the Gallup area, New Mexico
Samuel Wilson West
1961, Circular 443
A thick succession of sedimentary rocks (about 6,000 feet) underlies the town of Gallup and crops out nearby. Although all the sedimentary rocks are capable of yielding some water, only a few units of sandstone and limestone yield water in sufficient quantity and of acceptable quality to be considered as...
Sonic depth sounder for laboratory and field use
E.V. Richardson, Daryl B. Simons, G.J. Posakony
1961, Circular 450
The laboratory investigation of roughness in alluvial channels has led to the development of a special electronic device capable of mapping the streambed configuration under dynamic conditions. This electronic device employs an ultrasonic pulse-echo principle, similar to that of a fathometer, that utilizes microsecond techniques to give high accuracy in...
Preliminary estimate of water used in southeast river basins, 1960
Kenneth Allen MacKichan, John Craig Kammerer
1961, Circular 449
The estimated withdrawal use of water in the Southeast River Basins during 1960 was about 3,900 mgd exclusive of water used to develop waterpower and exclusive of water used by the Savannah River Plant of the U.S. Atomic Energy Commission. This estimated use amounts to 770 gallons per capita per...
Urban growth and the water regimen
John Savini, J.C. Kammerer
1961, Water Supply Paper 1591-A
The continuing growth and concentration of population and industry in urban and suburban areas in recent decades has caused a complex merging of social, economic, and physical problems, The interrelationships of man and his use and development of the land and water resources is a particularly significant aspect of urbanization,...
Occurrence of minor elements in water
W. H. Durum, Joseph Haffty
1961, Circular 445
Three basic studies, using spectrographic methods, have been used to establish the occurrence of minor elements in natural waters. One study, of oceanborne chemicals in principal rivers, has established a method for the quantitative analysis of many minor elements. Strontium, barium, lithium, rubidium, chromium, nickel, copper, lead, boron, titanium, molybdenum,...
Availability of ground water in Lyon County, Minnesota
Harry G. Rodis
1961, Circular 444
Lyon County is in southwestern Minnesota, about 150 miles southwest of Minneapolis and St. Paul The basement rocks in the area consist of granite and quartzite of Precambrian age. These materials are in turn overlain by shale and sandstone of Cretaceous age, glacial drift of Pleistocene age, and alluvium of...
Floods in New York, magnitude and frequency
F. Luman Robison
1961, Circular 454
This report presents a practical means of predicting the probable magnitude of floods on streams in New York State. Because of the limited amount of data on small drainage basins this method is not applicable to sites where the drainage area is less than 10 square miles or to streams...
