Ground-water-use trends in the Twin Cities metropolitan area, Minnesota, 1880-1980
M.A. Horn
1983, Water-Resources Investigations Report 83-4033
Detailed ground-water-use information from 1880 to 1980 has been collected and analyzed for the Twin Cities metropolitan area. Interpretation of historic water-use data was required to help water-resource planners and managers assess future trends in water use. Data were also needed for three computer-simulation models of ground-water flow being developed...

1983, Water-Resources Investigations Report 83-4146
Five Jurassic and Cretaceous formations in the Judith basin of central Montana were investigated with a three-dimensional model to improve the understanding of water flow in the Kootenai aquifer. To accomplish this objective, of water flow in the aquifers and two intervening confining layers was constructed from existing data. A...
Injection of treated wastewater for ground-water recharge in the Palo Alto Baylands, California, hydraulic and chemical interactions — Preliminary report
S. N. Hamlin
1983, Water-Resources Investigations Report 82-4121
An injection-extraction well network in the Palo Alto Baylands along the San Francisco Bay, California, was designed to flush the shallow aquifer system of saline water and prevent further inland saline contamination. Clogging processes and solution migration in the vicinity of one injection well were studied. Cyclic evaporative concentration of...

A two-dimensional graphing program for the Tektronix 4050-series graphics computers
K.L. Kipp
1983, Water-Resources Investigations Report 83-4087
A refined, two-dimensional graph-plotting program was developed for use on Tektronix 4050-series graphics computers. Important features of this program include: any combination of logarithmic and linear axes, optional automatic scaling and numbering of the axes, multiple-curve plots, character or drawn symbol-point plotting, optional cartridge-tape data input and plot-format storage, optional...
Source, use, and disposition of water in Florida, 1980
S.D. Leach
1983, Water-Resources Investigations Report 82-4090
An average of 21,206 million gallons of water was withdrawn for use in Florida each day for the combined use for public supplies , rural domestic and livestock, industrial self-supplied, irrigation, and thermoelectric power generation. This amount, broken down into 7,309 millions gallons per day of freshwater and 13,897 million...
Computer routines for probability distributions, random numbers, and related functions
W. Kirby
1983, Water-Resources Investigations Report 83-4257
Use of previously coded 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...
Reconnaissance of surface-water resources in the Kobuk River basin, Alaska, 1979-80
J.M. Childers, D.R. Kernodle
1983, Water-Resources Investigations Report 83-4027
Surface water data were collected at selected sites in the Kobuk River Basin in northwest Alaska in August 1979 and April 1980. In August 1979, frequent heavy rains caused abnormally high flows in the basin; unit runoff values, computed from discharge measurements at 25 sites, ranged from 0.08 to 12.2...

Water resources of the Santa Fe River basin, Florida
J. D. Hunn, L. J. Slack
1983, Water-Resources Investigations Report 83-4075
The Santa Fe River basin is a 1,384 square-mile area in north-central Florida. The principal source of water is the Floridan aquifer, a sequence of limestone beds, the upper 300 to 800 feet of which contain potable water. The western part of the basin has the greatest potential yields for...

Edward A. du Bray
1983, Open-File Report 83-370
Sixteen well-defined geochemical anomalies associated with felsic plutons and (or) muscovite-bearing plutons of Proterozoic age have been identified in the eastern and southeastern Arabian Shield.
