Impacts of the Tampa Bypass Canal system on the areal hydrology, Hillsborough County, Florida
R. L. Knutilla, M. A. Corral
1984, Water-Resources Investigations Report 84-4222
Construction of the Tampa Bypass Canal, Florida has resulted in an increase in streamflow from the canal area. Base-flow discharge is more than twice preconstruction amounts. Discharge from springs has decreased by one half or more. Ground-water levels show an increase of up to 4 feet near structure S-160 due...
Comment on the International Atomic Energy Agency Report on the Advisory Group Meeting on Stable Isotope Reference Samples for Geochemical and Hydrological Investigation, Vienna, Austria, September 19-21, 1983
T.B. Coplen, Irving Friedman, J. R. O’Neil
1984, Water-Resources Investigations Report 84-4136
According to U.S. Geological Survey records, a report prepared by R. Gonfiantini summarizing the findings and recommendations of the 1983 Advisory Group Meeting on Stable Isotope Reference Samples for Geochemical and Hydrologic Investigations held in Vienna does not accurately represent the consultants ' consensus on three important points. The consultants...
Trace metals in Suisun Bay, California: A preliminary report
S. N. Luoma, P. V. Cascos, R. M. Dagovitz
1984, Water-Resources Investigations Report 84-4170
A 5-month partial study (February to July 1983) was completed in Suisun Bay, a shallow embayment of San Francisco Bay, Calif., to determine characteristic heavy metal concentrations present in sediments and organisms (Corbicula clams) prior to possible discharge of San Luis Drain irrigation tile return water. Preliminary results show sediments...
Use of selected basin characteristics to estimate mean annual runoff and peak discharges for ungaged streams in drainage basins containing strippable coal resources, northwestern New Mexico
H.R. Hejl
1984, Water-Resources Investigations Report 84-4260
Equations in this report can be used to estimate mean annual runoff and peak discharges for 2-, 5-, 10-, 25-, and 100-year recurrence intervals for ungaged streams in drainage basins containing strippable coal resources in northwestern New Mexico. These streamflow characteristics are related to basin characteristics that were found to...
Hydrogeology of well-field areas near Tampa, Florida, phase 2 — Development and documentation of a quasi-three-dimensional finite-difference model for simulation of steady-state ground-water flow
C. B. Hutchinson
1984, Water-Resources Investigations Report 84-4002
This report describes a quasi-three-dimensional finite-difference model for simulation of steady-state ground-water flow in the Floridan aquifer over a 932-square-mile area that contains 10 municipal well fields. The over-lying surficial aquifer contains a water table and is coupled to the Floridan aquifer by leakage term that represents flow through a...
Ground-water resources of the White River basin, Randolph County, Indiana
W.W. Lapham, L. D. Arihood
1984, Water-Resources Investigations Report 83-4267
The two major aquifer systems in Randolph County, Indiana are sand and gravel and bedrock (limestone, dolomite, and shale of Silurian to Odovician age). The average thickness of the sands and gravels is 15 ft, and the aquifers are areally discontinuous. The bedrock aquifer underlies the entire study area and...
Evaluation of the potential for artificial ground-water recharge in eastern San Joaquin County, California — Phase 2
R. L. Ireland
1984, Water-Resources Investigations Report 83-4207
In response to the increasing demand on water supplies and declining water levels in eastern San Joaquin County, the U.S. Geological Survey, in cooperation with the San Joaquin County Flood Control and Water Conservation District, is evaluating the potential for artificially recharging the aquifer system in eastern San Joaquin County,...
Effects of surface coal-mine reclamation on stream quality in a small watershed near Nelsonville, southeastern Ohio
S. M. Hindall
1984, Water-Resources Investigations Report 84-4179
Abandoned surface coal mines in southeastern Ohio have caused degradation of the area's water resources. A study began in 1981 to determine the effects of abandoned-mine reclamation on water quality in the 'Yost tract' near Nelsonville, Ohio. Data on streamflow, water quality, and sedimentation were collected in Yost Run before,...
The ground-water resources in the Ross Barnett Reservoir area, Mississippi
W. T. Oakley
1984, Water-Resources Investigations Report 84-4160
The Ross Barnett Reservoir area occupies about 78 sq mi of a 490 sq mi study area northeast of the City of Jackson, MS. For several years, water use in the area has increased and during 1983 about 0.57 mil gal/day were obtained from groundwater sources. Virtually all groundwater in...
Low-flow transport models for conservative and sorbed solutes — Uvas Creek, near Morgan Hill, California
A. P. Jackman, R. A. Walters, V. C. Kennedy
1984, Water-Resources Investigations Report 84-4041
Models describing low-flow transport of conservative (nonreactive) and reactive solutes, which adsorb on the streambed, are developed and tested. Temporary storage within the bed plays an important role in solute movement. Three different models of bed-storage processes are developed for conservative solutes. One model assumes the bed is a well-mixed,...
Potential ground-water level changes in the Mississippi River alluvial aquifer in response to proposed navigation improvements on the Yazoo River in Mississippi
A. G. Lamonds, J. M. Kernodle
1984, Water-Resources Investigations Report 84-4039
A proposed navigation project on the Yazoo River between Vicksburg and Greenwood, Mississippi, will increase minimum river stages by more than 19 feet at the site of the proposed lock and dam near Vicksburg, and will decrease minimum river stages by 2 to 7 feet in much of the upper...
Effects of hydraulic borehole mining on ground water at a test site in northeast St Johns County, Florida
P. S. Hampson
1984, Water-Resources Investigations Report 83-4149
An experimental mining project was conducted in northeast St. Johns County, Florida, to determine the feasibility of extracting deeply buried phosphate ore by hydraulic borehole mining techniques. The phosphate zone is between 232 and 250 feet below land surface and consists of approximately equal proportions of fine-grained phosphate, sand, and...

R. D. Lamke
1984, Water-Resources Investigations Report 84-4096
This report documents the results of a study of the cost-effectiveness of the stream-gaging program in Alaska. Data uses and funding sources were identified for the 110 continuous stream-gaging stations that were being operated in September 1983 with a budget of about $1,700,000 per year.However, for the purposes of the...

A.H. Handy, J. R. Stark
1984, Water-Resources Investigations Report 83-4253
Sleeping Bear Dunes National Lakeshore in a water-rich area. It borders Lake Michigan and several small streams flow through the park to the lake. Small lakes are numerous within the park and near its boundaries. Ground water is available at most places in the park and wells yield as much...
Geohydrologic reconnaissance of drainage wells in Florida
J. O. Kimrey, L.D. Fayard
1984, Water-Resources Investigations Report 84-4021
Drainage wells are used to inject surface waters directly into an aquifer, or shallow ground waters directly into a deeper aquifer, primarily by gravity. Such wells in Florida may be grouped into two broad types: (1) surface-water injection wells, and (2) interaquifer connector wells. Drainage wells of the first type...

J. E. Kircher, Richard S. Dinicola, R.F. Middelburg
1984, Water-Resources Investigations Report 84-4048
Monthly values were computed for water-quality constituents at four streamflow gaging stations in the Upper Colorado River basin for the determination of trends. Seasonal regression and seasonal Kendall trend analysis techniques were applied to two monthly data sets at each station site for four different time periods. A recently developed...
