Hydrogeology, chemical quality, and availability of ground water in the Upper Floridan aquifer, Albany area, Georgia
D.W. Hicks, H.E. Gill, S.A. Longsworth
1987, Water-Resources Investigations Report 87-4145
Large withdrawals of groundwater in the 1500 sq mi Albany area of southwestern Georgia have lowered water levels in deep aquifers as much as 140 ft. This study was conducted to evaluate the development potential of the shallow Upper Floridan aquifer as an alternate source of groundwater, especially for public...
Water resources of Walworth County, South Dakota
Jack Kume, Lewis Howells
1987, Water-Resources Investigations Report 85-4015
The water resources of Walworth County, South Dakota are for the most part undeveloped. In 1978, only about 10,000 acre-feet of water was used for irrigation, stock, domestic, and public supplies; most of this water came form Lake Oahe on the Missouri River, and was used for irrigation. The lake...
Flooding of December 29, 1984 through January 2, 1985, in northern New York State, with flood profiles of the Black and Salmon rivers
Richard Lumia, P. M. Burke, William H. Johnston
1987, Water-Resources Investigations Report 86-4191
Precipitation, snowmelt, and resultant flooding throughout northern New York from December 28 through January 2, 1985, were investigated through a detailed analysis of 56 precipitation stations, 101 stage and/or discharge gaging stations, and 9 miscellaneous measurement sites. Flood damage to property and roads and bridges exceeded $5 million. Lewis and...
Ground-water resources of Flagler County, Florida
A. S. Navoy, L. A. Bradner
1987, Water-Resources Investigations Report 87-4021
Groundwater is the only significant source of potable water in Flagler County. Usable water occurs in the Upper Floridan aquifer, the intermediate population is expected to place stresses on the water resources of the county. Although rainfall averages almost 50 in/yr, most of the water leaves as evapotranspiration and streamflow....

Discharge ratings for control gates at Mississippi River lock and dam 21, Quincy, Illinois
A.J. Heinitz
1987, Water-Resources Investigations Report 87-4155
The water levels of the navigation pools on the Mississippi River are maintained by the operation of tainter and roller gates at the locks and dams. Discharge ratings for the gates on Lock and Dam 21, at Quincy, Illinois, were developed from current meter discharge measurements made in the forebays...
Discharge ratings for control gates at Mississippi River Lock and Dam 18, Gladstone, Illinois
A.J. Heinitz
1987, Water-Resources Investigations Report 87-4110
The water level of the navigation pools on the Mississippi River are maintained by the operation of tainter and roller gates at the locks and dams. Discharge ratings for the gates on Lock and Dam 18, at Gladstone, Illinois, were developed from current meter discharge measurements made in the forebays...
Method for estimating the magnitude and frequency of floods at ungaged sites on unregulated rural streams in Iowa
O. G. Lara
1987, Water-Resources Investigations Report 87-4132
This report provides techniques and procedures for estimating the probable magnitude and frequency of floods at ungaged sites on Iowa streams. Physiographic characteristics were used to define the boundaries of five hydrologic regions. Regional regression equations that relate the size of the drainage area to flood magnitude are defined for...

Documentation of computer program VS2D to solve the equations of fluid flow in variably saturated porous media
E.G. Lappala, R. W. Healy, E.P. Weeks
1987, Water-Resources Investigations Report 83-4099
This report documents FORTRAN computer code for solving problems involving variably saturated single-phase flow in porous media. The flow equation is written with total hydraulic potential as the dependent variable, which allows straightforward treatment of both saturated and unsaturated conditions. The spatial derivatives in the flow equation are approximated by...
Review of literature on the finite-element solution of the equations of two-dimensional surface-water flow in the horizontal plane
Jonathan K. Lee, David C. Froehlich
1987, Circular 1009
Published literature on the application of the finite-element method to solving the equations of two-dimensional surface-water flow in the horizontal plane is reviewed in this report. The finite-element method is ideally suited to modeling two-dimensional flow over complex topography with spatially variable resistance. A two-dimensional finite-element surface-water flow model with...

Rb-Sr isotopic studies of postorogenic granites from the eastern Arabian Shield, Kingdom of Saudi Arabia
J. S. Stuckless, Kiyoto Futa
1987, Open-File Report 87-507
Thirteen Rb-Sr whole-rock isochrons for postorogenic granites of the eastern Arabian Shield yield ages that range from 567 to 617 Ma, a similar range to that previously determined ages for leucocratic, evolved granites in that region. The dated plutons range widely in terms of degree of petrologic evolution from primitive...
