Geology and ground-water resources of Laramie County, Wyoming
Marlin E. Lowry, Marvin A. Crist, John R. Tilstra
1967, Water Supply Paper 1834
Laramie County, an area of 2,709 square miles, is in the southeast corner of Wyoming. Rocks exposed there range in age from Precambrian to Recent. The most extensive aquifers in the county are the White River Formation of Oligocene age, which is as much as 500 feet thick and consists...
Roughness characteristics of natural channels
Harry Hawthorne Barnes
1967, Water Supply Paper 1849
Color photographs and descriptive data are presented for 50 stream channels for which roughness coefficients have been determined. All hydraulic computations involving flow in open channels require an evaluation of the roughness characteristics of the channel. In the absence of a satisfactory quantitative procedure this evaluation remains chiefly an art....
Ground-water hydrology of the Punjab region of West Pakistan, with emphasis on problems caused by canal irrigation
D.W. Greenman, W.V. Swarzenski, G.D. Bennett
1967, Water Supply Paper 1608-H
Rising water tables and the salinization of land as the result of canal irrigation threaten the agricultural economy of the Punjab. Since 1954 the Water and Soils Investigation Division of the West Pakistan Water and Power Development Authority has inventoried the water and soils resources of the Punjab and investigated...
Water requirements of the iron and steel industry
Faulkner B. Walling, Louis Ethelbert Otts Jr.
1967, Water Supply Paper 1330-H
Twenty-nine steel plants surveyed during 1957 and 1958 withdrew from various sources about 1,400 billion gallons of water annually and produced 40.8 million tons of ingot steel. This is equivalent to about 34,000 gallons of water per ton of steel. Fifteen iron ore mines and fifteen ore concentration plants together...
Geology and hydrology between Lake McMillan and Carlsbad Springs, Eddy County, New Mexico
Edward Riley Cox
1967, Water Supply Paper 1828
The hydrology of the Pecos River valley between Lake McMillan and Carlsbad Springs, Eddy County, N. Mex., is influenced by facies changes in rocks of Permian age. Water stored for irrigation leaks from Lake McMillan into evaporite rocks, principally gypsum, of the Seven Rivers Formation and from Lake Avalon into...
Determination of phenoxy acid herbicides in water by electron-capture and microcoulometric gas chromatography
D.F. Goerlitz, William L. Lamar
1967, Water Supply Paper 1817-C
A sensitive gas chromatographic method using microcoulometric titration and electron-capture detection for the analysis of 2,4-D, silvex, 2,4,5-T, and other phenoxy acid herbicides in water is described. The herbicides are extracted from unfiltered water samples (800-1,000 ml) by use of ethyl ether ; then the herbicides are concentrated and esterilied....
Specific yield: compilation of specific yields for various materials
A.I. Johnson
1967, Water Supply Paper 1662-D
Specific yield is defined as the ratio of (1) the volume of water that a saturated rock or soil will yield by gravity to (2) the total volume of the rock or soft. Specific yield is usually expressed as a percentage. The value is not definitive, because the quantity of...
Geology and ground water of the Savannah River Plant and vicinity, South Carolina
George E. Siple
1967, Water Supply Paper 1841
The area described in this report covers approximately 2,600 square miles in west-central South Carolina and includes the site of the Savannah River Plant, a major production facility of the U.S. Atomic Energy Commission. The climate, surface drainage, and land forms of the study area are typical of the southern...
Definition of stage-discharge relation in natural channels by step-backwater analysis
James F. Bailey, H.A. Ray
1967, Water Supply Paper 1869-A
The step-backwater method was investigated as a technique for defining the upper part of stage-discharge relation in a natural channel. State-discharge relations at 28 sites were computed by using this technique and compared with corresponding stage-discharge relations defined by current-meter measurements. In general, the agreement is remarkably good, and the...
Summary of hydrologic and physical properties of rock and soil materials, as analyzed by the hydrologic laboratory of the U.S. Geological Survey, 1948-60
D. A. Morris, A.I. Johnson
1967, Water Supply Paper 1839-D
The Hydrologic Laboratory was established in 1948 to serve as the central testing laboratory for the Water Resources Division of the U.S. Geological Survey. Since then, thousands of samples of rock and soil materials have been analyzed in the laboratory. Analytical data on samples from 42 States and for the...
Analysis of aquifer tests in the Punjab region of West Pakistan
Gordon D. Bennett, Ata-Ur-Rehman, Ijaz Ahmed Sheikh, Sabire Alr
1967, Water Supply Paper 1608-G
The results of 141 pumping tests in the Punjab Plain of West Pakistan are reported. Methods of test analysis are described in detail, and an outline of the theory underlying these methods is given. The lateral permeability of the screened interval is given for all tests; the specific yield of...
Ground-water resources of the Pascagoula River basin, Mississippi and Alabama
Roy Newcome
1967, Water Supply Paper 1839-K
Abundant ground-water resources underlie the Pascagoula River basin. These resources have been developed intensively in only a few places--namely, Hattiesburg, Laurel, Meridian, and Pascagoula. Seepage from the ground water reservoirs sustains the base flows of the Leaf, Chickasawhay, Pascagoula, and Escatawpa Rivers and their tributaries. The fresh-water-bearing section is 300...
Water resources of the Marquette Iron Range area, Michigan
Sulo Werner Wiitala, Thomas Gwyn Newport, Earl L. Skinner
1967, Water Supply Paper 1842
Large quantities of water are needed in the beneficiation and pelletizing processes by which the ore mined from low-grade iron-formations is upgraded into an excellent raw material for the iron and steel industry. Extensive reserves of low-grade iron-formation available for development herald an intensification of the demands upon the area's...
Swatara Creek basin of southeastern Pennsylvania: An evaluation of its hydrologic system
Wilbur Tennant Stuart, William J. Schneider, James W. Crooks
1967, Water Supply Paper 1829
Local concentrations of population in the Swatara Creek basin of Pennsylvania find it necessary to store, transport, and treat water because local supplies are either deficient or have been contaminated by disposal of wastes in upstream areas. Water in the basin is available for the deficient areas and for dilution...
