Drainage area and river mileage of Nebraska streams part I
Gordon G. Jamison
1974, Open-File Report 7404
The value of stream discharge data for hydrologic studies is enhanced by the availability of accurate information on size of area drained, distance between selected sites along stream course, and hydraulic gradients. Information on the location of cultural and natural features that affect streamflow also is valuable for hydrologic studies,...
Hydrologic Unit Map -- 1974, State of Michigan
Water Resources Division, U.S. Geological Survey
1974, Hydrologic Unit 22
This map and accompanying table show Hydrologic Units that are basically hydrographic in nature.  The Cataloging Units shown will supplant the Cataloging Units previously used by the U.S. Geological Survey in its Catalog of Information on Water Data (1966-72).  The previous U.S. Geological Survey Catalog-Indexing System was by map number...
Floods of January 1974 in Washington
R.J. Longfield
1974, Report
Record floods occurred in parts of Washington during January 14-21, 1974. The floods resulted from runoff from warm, moderately heavy rain that continued most of the week, augmented by runoff from the rapid melting of a near-record snowpack that extended to low elevations. New record peak flows occurred at many...
Stratigraphic nomenclature in reports of the U.S. Geological Survey
George V. Cohee
1974, Report
The Geologic Names Committee of the United States Geological Survey was first organized on February 17, 1899, " ... to consider all names of geologic formations or other divisions of rock classifications with a view to determining whether they comply with the rules of nomenclature adopted for the Survey publications...
Prehnite- and pumpellyite-bearing mineral assemblages, west side of the Appalachian metamorphic belt, Pennsylvania to Newfoundland
E-an Zen
1974, Journal of Petrology (15) 197-242
Prehnite- and/or pumpellyite-bearing meta-igneous rocks are found on the west side of the Appalachian metamorphic belt (1) near Jonestown, south-eastern Pennsylvania; (2) on Rensselaer Plateau, eastern New York; (3) near Quebec City, Quebec; and (4) at Little Port, Humber Arm, western Newfoundland. The assemblages critical to determining the conditions...
Sandstone distribution patterns in the Pocahontas Formation of southwest Virginia and southern West Virginia
Kenneth J. Englund
G. Briggs, editor(s)
1974, Book chapter, Carboniferous of the southeastern United States
The Pocahontas Formation is a clastic wedge of sandstone, siltstone, shale, coal, and underclay that is transitional between underlying marine strata of Mississippian age and overlying continental beds of Pennsylvanian age. It attains a maximum thickness of 750 ft. at the southeastern edge of the Appalachian coal field and thins...
Water-management studies of a stream-aquifer system, Arkansas River Valley, Colorado
O. James Taylor, Richard R. Luckey
1974, Groundwater (12) 22-38
A mathematical model was developed and used to simulate the stream-aquifer system in the Arkansas River valley in southeastern Colorado, from Pueblo to the Colorado-Kansas State line. The model simulates the interrelations among ground water and surface water including reservoirs, losses, and transmountain diversions, utilizing various water-distribution rules. The model...
A note on costs of collecting hydrometric flow data in the United States
W. B. Langbein, G. E. Harbeck Jr.
1974, Hydrological Sciences Bulletin (19) 227-229
Information for comparing costs of collecting hydrometric data in different countries may promote efficiency of operations. The hydrometric programme in the United States consists of 8400 full-record stations and an equal number of partial-record stations operated by 47 district offices. A sampling of four districts selected to represent the range...
Determination of selenium in water
M. Lansford, E. M. McPherson, Marvin J. Fishman
1974, Atomic Absorption Newsletter (13) 103-105
The determination of selenium by hydride generation atomic absorption spectrophotometry using zinc is widely used. Very little is mentioned, however, on possible interferences. In an attempt to use this technique for the determination of selenium in natural waters, interferences were found. The most serious interference occurred when arsenic was present....
