Water resources data for Florida, water year 1978--Volume 4. Northwest Florida
Water Resources Division, U.S. Geological Survey
1979, Water Data Report FL-78-4
Water resources data for the 1978 water year for northeast Florida consist of records of stage, discharge, and water quality of streams; elevation and water quality of lakes and reservoirs; water-levels and water quality of wells; and discharge and water quality of springs. Additional water data were collected at various...
Chemical analyses of surface water in Illinois, 1975-77--Volume III, Ohio River tributaries and Mississippi River tributaries south of Illinois River basin
David Grason, R. W. Healy
1979, Water-Resources Investigations Report 79-25
Samples of surface water were collected and analyzed by the Illinois Environmental Protection Agency. The results from water years 1975 to 1977 are presented in three volumes. The history of sampling and analytical methods used during that period are summarized. Stream discharge data from records of the U.S. Geological Survey...
Streamflow Estimates in Selected Wisconsin Streams
R.P. Novitzki
1979, Open-File Report 79-1282
The Wisconsin Department of natural Resources needs streamflow information in lake basins where lake-rehabilitation programs are implemented but where long-term stream-gaging stations are not justified. The U.S. Geological Survey provided streamflow estimates for 24 streams in Wisconsin. The estimates were made by the use of (1) midmonthly measurements, (2) basin...
Uranium results for 147 water samples from the Elkhorn Wilderness Study Area, Montana
John B. McHugh, William R. Miller
1979, Open-File Report 79-675
One hundred forty seven water samples were corrected from the Elkhorn Wilderness during the summer of 1977 as a part of a mineral resource assessment study. Each sample was analyzed for uranium. Specific conductance and pH were also measured. Sample analyses and site locations are presented in this report....
Documentation of a finite-element two-layer model for simulation of ground-water flow
Michael J. Mallory
1979, Water-Resources Investigations Report 79-18
This report documents a finite-element model for simulation of ground-water flow in a two-aquifer system where the two aquifers are coupled by a leakage term that represents flow through a confining layer separating the two aquifers. The model was developed by Timothy J. Durbin (U.S. Geological Survey) for use in...
Water resources of the southern Powder River area of southeastern Montana
W. Roger Miller
1979, Open-File Report 79-343
The southern Powder River area comprises about 2,230 square miles in southeastern Montana. Sedimentary rocks beneath this area range in age from Cambrian to Holocene and attain a maximum thickness of about 12,000 feet. Rocks exposed in the study area range in age from Late Cretaceous to Holocene.Water for domestic,...
Water in the Elizabethtown area: A study of a limestone terrane in north-central Kentucky
T. W. Lambert
1979, Water-Resources Investigations Report 79-53
The Elizabethtown area of north-central Kentucky contains aquifers and streams that yield adequate quantities of water of suitable quality for most individual domestic needs as well as for industrial, public supply, and irrigation uses.The area consists of typical karst with numerous sinkholes and subsurface drainage. The bedrock structure controls, in...
Primary and secondary faulting in the Najd fault system, Kingdom of Saudi Arabia
John McMahon Moore
1979, Open-File Report 79-1661
The Najd fault system is a major transcurrent (strike-slip) fault system of Proterozoic age in the Arabian Shield. The system is a braided complex of parallel and curved en echelon faults. Complex arrays of secondary structures including strike-slip, oblique-slip, thrust, and normal faults, together with folds and dike swarms, are...
