Ground water in the Dickson area of the western Highland Rim of Tennessee
M. W. Bradley
1984, Water-Resources Investigations Report 82-4088
A hydrologic study of the Dickson, Tennessee, area provided additional information on the occurrence of ground water in the Mississippian carbonate rocks of the western Highland Rim. Twenty-six test wells were drilled to determine the occurrence of ground water in relation to topographic position, regolith thickness, streamflow gains or losses,...
Maps showing ground-water units and withdrawal, Basin and Range Province, Texas
B. T. Brady, M. S. Bedinger, John Mikels
1984, Water-Resources Investigations Report 83-4121-A
This report on ground-water units and withdrawal in the Basin and Range province of Texas (see index map) was prepared as part of a program of the U.S. Geological Survey to identify prospective regions for further study relative to isolation of high-level nuclear waste (Bedinger, Sargent, and Reed, 1984), utilizing...
Source, movement, and effects of nitrogen and phosphorus in three ponds in the headwaters of Hop Brook, Marlborough, Massachusetts
John C. Briggs, William D. Silvey
1984, Water-Resources Investigations Report 84-4017
The headwaters of Hop Brook near Marlborough, Massachusetts, contain a series of three in-line ponds--Hager Pond, Brist Millpond, and Carding Millpond--which receive over half of their surface-water inflow as effluent from the Marlborough Easterly Wastewater Treatment Plant. These ponds have a history of summer algal blooms and fish kills. Water...
A reconnaissance study of saltwater contamination in the El Dorado aquifer, Union County, Arkansas
Matthew E. Broom, T. F. Kraemer, William V. Bush
1984, Water-Resources Investigations Report 84-4012
Since 1960 chloride concentrations in the El Dorado aquifer have increased near El Dorado, Arkansas. The aquifer is a major source for municipal and industrial water supply in Union County. Greatest withdrawal occurs near El Dorado. Because of this withdrawal, the potentiometric surface at El Dorado has been lowered more...
Impact of development on availability and quality of ground water in eastern Nassau County, Florida, and southeastern Camden County, Georgia
D.P. Brown
1984, Water-Resources Investigations Report 83-4190
The primary sources of water in the area are from the surficial and Floridan aquifers. The surficial aquifer, consisting of thin permeable zones of sand, shell, and limestone, provides limited water supplies (10-50 gallons per minute). Its estimated transmissivity ranges from less than 100 to 10,000 feet squared per day....
Atmospheric deposition of selected chemicals and their effect on nonpoint-source pollution in the Twin Cities Metropolitan Area, Minnesota
R. G. Brown
1984, Water-Resources Investigations Report 83-4195
Atmospheric deposition and subsequent runoff concentrations of total Kjeldahl nitrogen, dissolved nitrite-plus-nitrate nitrogen, total phosphorus, total sulfate (only for atmospheric deposition), total chloride, and total lead were studied from April 1 to October 31, 1980, in one rural and three urban watersheds in the Twin Cities Metropolitan Area, Minnesota. Seasonal...
Hydrologic effects of impoundments in Sherburne National Wildlife Refuge, Minnesota
R. G. Brown
1984, Water-Resources Investigations Report 84-4175
The hydrologic effects of proposed impoundments in Sherburne National Wildlife Refuge were found to be insignificant with respect to both ground- and surface-water flow patterns and water quality. Monitoring of water levels in 23 observation wells and of discharge in the St. Francis River during 1980 and 1981 has shown...
Flow routing in the Susquehanna River basin: Part V – Flow-routing models for the West Branch Susquehanna River basin, Pennsylvania
S. A. Brua
1984, Water-Resources Investigations Report 82-4049
Digital-computer, daily-flow routing models were developed for four consecutive reaches of the West Branch Susquehanna River between Curwensville and Lewisburg, Pennsylvania. These models will enable water-resources managers to evaluate efficiently the effect of present and future water-resources developments on streamflows at six locations along the West Branch Susquehanna River. The...
Cost-effectiveness of the stream-gaging program in Iowa
I.L. Burmeister, O. G. Lara
1984, Water-Resources Investigations Report 84-4171
This report documents the results of a study of the cost-effectiveness of the stream-gaging program in Iowa. Data uses and funding sources were identified for the 122 surface-water stations (including reservoir, lake, stage only, and miscellaneous stations) operated by the U. S. Geological Survey in Iowa. There are 110 continuous...
Predictive simulation of alternatives for managing the water resources of North Fork Solomon River Valley between Kirwin Dam and Waconda Lake, north-central Kansas
R.D. Burnett
1984, Water-Resources Investigations Report 84-4249
Since 1974 water levels in the alluvial aquifer of the North Fork Solomon River Valley in north-central Kansas have decreased due to increases in ground-water pumpage, decreases in availability of surface water for irrigation, and below-average precipitation. A finite-element model was developed in cooperation with the U.S. Bureau of Reclamation...
Simulated effects of an artificial-recharge experiment near Proctor, Logan County, Colorado
A.W. Burns
1984, Water-Resources Investigations Report 84-4010
An artificial-recharge experiment was conducted near Proctor, Colorado in which a computed 620 acre-feet were pumped from a well during a 4-month period. A computed 420 acre-feet were delivered at the potential reservoir site, and the remaining 200 acre-feet leaked from the pipeline. No pond was created due to the...
Physical basis and potential estimation techniques for soil erosion parameters in the Precipitation-Runoff Modeling System (PRMS)
W. P. Carey, Andrew Simon
1984, Water-Resources Investigations Report 84-4218
Simulation of upland-soil erosion by the Precipitation-Runoff Modeling System currently requires the user to estimate two rainfall detachment parameters and three hydraulic detachmment paramenters. One rainfall detachment parameter can be estimated from rainfall simulator tests. A reformulation of the rainfall detachment equation allows the second parameter to be computed directly....
Leaching study of oil shale in Kentucky: With a section on hydrologic reconnaissance of the oil shale outcrop in Kentucky
Samuel S. Leung, D.W. Leist, R. W. Davis, Steven Cordiviola
1984, Water-Resources Investigations Report 84-4073
Oil shales in Kentucky are rocks of predominantly Devonian age. The most prominant are the Ohio, Chattanooga, and New Albany Shales. A leaching study was done on six fresh oil shale samples and one retorted oil shale sample. Leaching reagents were distilled water, 0.0005 N sulfuric acid, and 0.05 N...
Enhanced job control language procedures for the SIMSYS2D two-dimensional water-quality simulation system
G.A. Karavitis
1984, Water-Resources Investigations Report 84-4052
The SIMSYS2D two-dimensional water-quality simulation system is a large-scale digital modeling software system used to simulate flow and transport of solutes in freshwater and estuarine environments. Due to the size, processing requirements, and complexity of the system, there is a need to easily move the system and its associated files...
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...
