Amazon River investigations, reconnaissance measurements of July 1963
Roy Edwin Oltman, H. O’R. Sternberg, F.C. Ames, L.C. Davis
1964, Circular 486
The first measurements of the flow of the Amazon River were made in July 1963 as a joint project of the University of Brazil, the Brazilian Navy, and the U.S. Geological Survey. The discharge of the Amazon River at Obidos was 7,640,000 cfs at an annual flood stage somewhat lower...
A magnetic anomaly of possible economic significance in southeastern Minnesota
Isidore Zietz
1964, Circular 489
An aeromagnetic survey in southeastern Minnesota by the U. S. Geological Survey in cooperation with the State of Minnesota has revealed a high-amplitude, linear, and narrow magnetic feature that suggests a possible source of Precambrian iron-formation of economic value. For the past few years the U. S. Geological Survey has...
Chemical quality of public water supplies of the United States and Puerto Rico, 1962
Charles N. Durfor, Edith Becker
1964, Hydrologic Atlas 200
Municipal water systems in the United States and Puerto Rico supply water for many commercial and industrial uses as well as for domestic wells. It is generally known that our water resources are unequally distributed throughout the country, but it is not quite so well understood that the quality of...
Hydrology and hydrogeology of Navajo Lake, Kane County, Utah
Milton Theurer Wilson, Harold E. Thomas
1964, Professional Paper 417-C
Navajo Lake, whose entire outflow disappears underground, is on the high Markagurit Plateau where the average annual precipitation is more than 30 inches. It nestles among the headwaters of several streams that flow into arid regions where competition for municipal, industrial, and irrigation water sup- plies is very keen. Several...
Extending Darcy's concept of ground-water motion
H.E. Skibitzke
1964, Professional Paper 411-F
The tensor nature of permeability and its effect in a given ground-water flow regime have been acknowledged by various investigators. The effect on the spread of a given dissolved substance can be qualitatively discussed on the basis of the tensor characteristic of the permeability coefficient. The correlation between the dispersion...
Reconnaissance bedrock geology of the Wabassus Lake quadrangle, Washington County, Maine
David M. Larrabee
1964, Miscellaneous Field Studies Map 282
Generally, shear zones in quadrangles of this area parallel the faults, especially those trending northeasterly. Additional faults and shear zones doubtless present in Wabassus Lake quadrangle but not shown for lack of field work in some areas, and lack of outcrops in others. Some lineaments seen on areal photographs, but...
