Preliminary delineation of salty ground water in the northern Atlantic Coastal Plain
Harold Meisler
1980, Open-File Report 81-71
Salty ground water underlies freshwater in the eastern part of the northern Atlantic Coastal Plain. The transition zone between freshwater and saltwater is represented in this report by a series of maps showing the depths to chloride concentrations of 250, 1,000, 10,000, and 18,000 milligrams per liter. The maps are...
Hydrology of Jumper Creek Canal basin, Sumter County, Florida
Warren Anderson
1980, Open-File Report 80-208
In 1960, floods caused extensive damage to agribusiness in Jumper Creek Canal basin. In 1962, a plan was developed for a proposed project to reduce the threat of floods. In 1976, a study of the hydrology of the basin was proposed to help evaluate this plan and to serve as...
Relationships between basic soils-engineering equations and basic ground-water flow equations
Donald G. Jorgensen
1980, Water Supply Paper 2064
The many varied though related terms developed by ground-water hydrologists and by soils engineers are useful to each discipline, but their differences in terminology hinder the use of related information in interdisciplinary studies. Equations for the Terzaghi theory of consolidation and equations for ground-water flow are identical under specific conditions....
Ground-water models for water resources planning
John E. Moore
1980, Open-File Report 80-581
In the past decade hydrologists have emphasized the development of computer-based mathematical models to aid in the understanding of flow, the transport of solutes, transport of heat, and deformation in the groundwater system. These models have been used to provide information and predictions for water managers. Too frequently, groundwater was...
Hydrogeologic data for the Mississippi Embayment of southeastern Missouri
Richard R. Luckey, Dale L. Fuller
1980, Open-File Report 79-421
The Mississippi embayment of southeastern Missouri is a 4 ,000-square-mile agricultural area that is presently (1979) undergoing rapid development for irrigation. In July 1974, a project was initiated to evaluate the water resources of the area, determine the extent of irrigation, and to assess the future potential for irrigation supplies....
Computer routines for probability distributions, random numbers, and related functions
W.H. Kirby
1980, Open-File Report 80-448
Use of previously codes and tested subroutines simplifies and speeds up program development and testing. This report presents routines that can be used to calculate various probability distributions and other functions of importance in statistical hydrology. The routines are designed as general-purpose Fortran subroutines and functions to be called from...
Ground-water appraisal of sand plains in Benton, Sherburne, Stearns, and Wright counties, central Minnesota
Gerald F. Lindholm
1980, Open-File Report 80-1285
Surficial-sand aquifers in 960 square miles of central Minnesota have been studied to determine the occurrence, availability, and suitability of the surficial aquifer as a source of water. The aquifer is being increasingly developed for irrigation. During the drought of 1976, nearly 24,000 acre-feet of ground water was withdrawn for irrigation,...
Hydrologic budget for Eagle Lake near Willmar, Minnesota
C. F. Myette
1980, Open-File Report 80-163
Eagle Lake occupies 890 acres of a 9,000-acre watershed in central Minnesota. Because of its proximity to Willmar, many homes and summer cabins have been built around the lake. Presently (1978), the shore is more than 90 percent developed. One effect of this development is accelerated eutrophication, most commonly shown...
Ground-water hydrology of James City County, Virginia
John F. Harsh
1980, Open-File Report 80-961
Urbanization and increase in water demand prompted a 2-year study of groundwater availability and quality in the county of James City. The coastal-plain sediments, parts of which underlie the county, are the largest source of groundwater in Virginia. Four aquifers form the complex aquifer system. Hydraulic characteristics vary from aquifer...
Basic elements of ground-water hydrology with reference to North Carolina
Ralph Carr Heath
1980, Open-File Report 80-44
This report was prepared as an aid to developing a better understanding of the groundwater resources of North Carolina. It consists of 46 essays grouped into five parts. The topics covered by these essays range from the most basic aspects of ground-water hydrology to the identification and correction of problems...
Water-resources investigations of the U.S. Geological Survey in Montana, October 1979 through September 1980
Water Resources Division, U.S. Geological Survey
1980, Open-File Report 80-222
This report describes water-resources investigations of the U.S. Geological Survey in Montana, October 1979 through September 1980. Programs consist of (1) collecting hydrologic data on a continuing basis, (2) conducting water-resources appraisals of surface and ground water, (3) conducting supportive research in hydrology and related fields, (4) disseminating water data...
Drainage areas of selected surface-water sites in Florida
Donald W. Foose
1980, Open-File Report 80-957
Drainage areas for about 1,500 surface-water sites on streams and lakes in Florida are contained in this report. Sites are described in relation to a nearby city or town, and are located by county, by latitude-longitude, and by topographic map on which it is located. In addition, the surface areas...
Hydrologic data from upper Grange Hall Creek basin, Northglenn, Adams County, Colorado
Dennis C. Hall, A.C. Duncan
1980, Open-File Report 80-578
Hydrologic data collected during 1977-79 as part of a water-resources investigation of storm runoff in Upper Grange Hall Creek basin, Adams County, Colo., are presented in this report. Data presented in tabular form consist of: (1) Estimated daily precipitation at one site (April through October, 1978 and 1979); (2) mean...
Quality of runoff from small watersheds in the Twin Cities Metropolitan Area, Minnesota - A project plan
M. A. Ayers, G. A. Payne, Gary L. Oberts
1980, Open-File Report 80-592
A program of water-quality sampling to define the relationships between land use, watershed characteristics, and the quantity, quality, and timing of runoff has been started for the Twin Cities metropolitan area of Minnesota. Ten major watersheds were chosen as representative of conditions in the metropolitan area. Each will be sampled...
Hydrologic evaluation of a hypothetical coal-mining site near Chrisney, Spencer County, Indiana
John S. Zogorski, Daniel S. Ramey, Paul W. Lambert, Jeffrey D. Martin, Robert E. Warner
