Interpolating water-table altitudes in west-central Kansas using kriging techniques
L. E. Dunlap, Joseph M. Spinazola
1984, Water Supply Paper 2238
Kriging is a regionalization technique that incorporates the autocorrelation between known data values in its estimation of values at unmeasured sites. This technique is reproducible, accepts irregularly spaced data, uses only measured values closely surrounding points at which values are estimated, is an exact interpolator at measured data points, and...
Hydrogeology of eastern Michaud Flats, Fort Hall Indian Reservation, Idaho
N.D. Jacobson
1984, Water-Resources Investigations Report 84-4201
Groundwater in Michaud Flats, southeastern Idaho, is developed extensively for irrigation and industry. Extensive clay beds overlie the Bighole Basalt and Sunbeam Formation, which yield most of the water for irrigation and industrial wells; artesian aquifers in these rock units have heads below land surface and near those in the...
Geohydrology of the valley-fill aquifer in the Cohocton area, upper Cohocton River, Steuben County, New York
David B. Terry, Timothy S. Pagano, Martha L. Shaw, Arlynn W. Ingram
1984, Water-Resources Investigations Report 85-4040
The Cohocton valley-fill aquifer, composed of outwash, kame, and alluvial sand and gravel, is highly productive and is in hydraulic contact with the Cohocton River. Potential well yields range from 50 to more than 1,000 gallons per minute. Most of the aquifer is under shallow water-table conditions and vulnerable to...
Maps showing altitude of the potentiometric surface and changes in water level of the Sparta sand and Memphis sand aquifers in Eastern Arkansas, spring 1983
Joe Edds, Daniel J. Fitzpatrick
1984, Water-Resources Investigations Report 84-4265
The Sparta Sand and the Memphis Sand aquifers are a major source of industrial and public water supply and a minor but locally significant source of water for agricultural purposes in eastern and south-central Arkansas. The potentiometric surface map for this aquifer, compiled from water-level measurements made during the spring...
Water-table contours, directions of ground-water movement, and measurements of inflow to American Falls Reservoir, southeastern Idaho, April 1984
H.W. Young
1984, Water-Resources Investigations Report 84-4269
In 1978 the U.S. Geological Survey began a 5-year study of the High Plains regional aquifer system to provide hydrologic information for evaluating the effects of long-term development of the aquifer and to develop a capability for predicting aquifer response to alternative changes in ground-water management. By use of a...
Ground water in the Fresno area, California; preliminary report
H. T. Mitten
1984, Water-Resources Investigations Report 83-4246
The U.S. Geological Survey, in cooperation with Fresno County, is developing a computer model of the unconfined aquifer system in the Fresno area. In the area, consolidated rocks are overlain by unconsolidated deposits. The unconsolidated deposits are divided into a lower fine-grained unit and an overlying coarse-grained unit. The system...
Physical and chemical characteristics of water in coal-mine ponds, eastern Oklahoma, June to November 1977-81
L. J. Slack, S. P. Blumer
1984, Open-File Report 84-446
Water at 102 sites in 59 coal-mine ponds in eastern Oklahoma was sampled at lease twice during June to November 1977-81 to determine temperature, specific conductance, dissolved oxygen, pH, and dissolved sulfate, chloride, iron, and manganese--as part of a study of the hydrology of the Oklahoma coalfield. These determinations show...
The evolution of the southern California uplift, 1955 through 1976
Robert O. Castle, Michael R. Elliot, Jack P. Church, Spencer H. Wood
1984, Professional Paper 1342
The southern California uplift culminated in 1974 as a 150- km-wide crustal swell that extended about 600 km eastward and east-southeastward from Point Arguello to the Colorado River and Salton Sea, respectively; it was characterized by remarkably uniform height changes between 1959 and 1974 of 0.30-0.35 m over at least...
Ground-water models as a management tool in Florida
C. B. Hutchinson
1984, Water-Resources Investigations Report 84-4016
Highly sophisticated computer models provide powerful tools for analyzing historic data and for simulating future water levels, water movement, and water chemistry under stressed conditions throughout the ground-water system in Florida. Models that simulate the movement of heat and subsidence of land in response to aquifer pumping also have potential...
