Chemical quality of Michigan streams
Warren W. Wood
1970, Circular 634
Concentrations of chemical constituents of Michigan streams exhibit regional patterns that are primarily a function of geology and evapotranspiration. However, in some areas waste disposal by municipal and industrial organizations has altered the natural distribution and concentrations of dissolved material. Concentration and areal distribution of chemical constitutents were found to...
A review of water resources of the Umiat area, northern Alaska
John R. Williams
1970, Circular 636
Surface-water supplies from the Colville River, small tributary creeks, and lakes are abundant in summer but limited in winter by low or zero flow in streams and thick ice cover on lakes. Fresh ground water occurs in unfrozen zones in alluvium and in the upper part of bedrock beneath the...
A strategy for the geologic exploration of the planets
M. H. Carr
1970, Circular 640
The geology of the planets bears directly on three basic aims of lunar and planetary exploration: determination of the origin and evolution of the solor system; determination of the origin and evolution of life; and clarification of the nature of the processes shaping man's terrestrial environment (National Academy of Sciences, 1966...
Sediment problems in urban areas
Harold P. Guy
1970, Circular 601-E
A recognition of and solution to sediment problems in urban areas is necessary if society is to have an acceptable living environment. Soil erosion and sediment deposition in urban areas are as much an environmental blight as badly paved and littered streets, dilapidated buildings, billboard clutter, inept land use, and...
Water as an urban resource and nuisance
H. E. Thomas, William Joseph Schneider
1970, Circular 601-D
Generally, when people speak of water as a resource, they are considering its good aspects and recognizing that it is essential for life and living. Sometimes or at some places or to some people, the same water may be annoying or unpleasant and thus a nuisance-for example, rain at a...
Water laws and concepts
H. E. Thomas
1970, Circular 629
Throughout human history various laws and customs have developed concerning the individual rights and rights in common to the waters of the earth. Many existing laws and concepts are clearly influenced by the environment in which they originated and reflect the relative abundance or scarcity of water. Many concepts reflect...
Elemental sulfur in Eddy County, New Mexico
Jim S. Hinds, Richard R. Cunningham
1970, Circular 628
Sulfur has been reported in Eddy County, N. Mex., in rocks ranging from Silurian to Holocene in age at depths of 0-15,020 feet. Targets of present exploration are Permian formations in the Delaware Basin and northwest shelf areas at depths of less than 4,000 feet. Most of the reported sulfur...
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...
Hydrologic implications of solid-water disposal
William Joseph Schneider
1970, Circular 601-F
The disposal of more than 1,400 million pounds of solid wastes in the United States each day is a major problem. This disposal in turn often leads to serious health, esthetic, and environmental problems. Among these is the pollution of vital ground-water resources. Of the six principal methods of solid-waste disposal...
