Summary of hydrologic data collected during 1977 in Dade County, Florida
John E. Hull
1979, Open-File Report 79-514
During 1977 rainfall was 1.52 inches above the long-term average in Dade County, Fla. Ground-water levels ranged from 0.3 foot above to 0.1 foot below average. The highest and lowest ground-water levels for the year were 1 foot below and 1 foot above their long-term average. In the Hialeah-Miami Springs...
A plan for study of flood hydrology of foothill streams in Colorado
Jerald F. McCain, John L. Ebling
1979, Open-File Report 79-1276
A comprehensive plan is presented for researching methods of flood-data analysis and informatin transfer for foothill areas, and for establishing a hydrologic data-collection network in the foothill areas of Colorado. The research will concentrate on three areas: (1) Developing methods to analyze flood peaks in foothill areas by using gaging-station...
Design of a network for monitoring ground-water quality in Minnesota
Marc F. Hult
1979, Open-File Report 79-1164
A network for monitoring the quality of water in the 13 principal aquifers in Minnesota has been designed and more than 400 wells and springs selected for sampling. The network organization includes four major elements; (1) point sampling, (2) point monitoring, (3) regional monitoring, and (4) site-specific monitoring. These elements...
Hydrogeologic features of the alluvial deposits in the Nowood River drainage area, Bighorn Basin, Wyoming
M. E. Cooley, William J. Head
1979, Open-File Report 79-1291
In the Nowood River drainage area, Wyoming, the principal deposits comprising the alluvial aquifer include the flood-plain and younger (generally undissected) alluvial-fan deposits and a unique boulder-fan gravel. Other deposits mapped, but virtually nonwater yielding, are the older (dissected) alluvial-fan, pediment, and terrace deposits. Terraces are capped by gravel and...
Ground-water monitoring at Santa Barbara, California: Phase 1— Coastal monitor-well installation and initial measurements
C. B. Hutchinson
1979, Open-File Report 79-923
Plans to reduce natural ground-water storage in the 7-square-mile Santa Barbara groundwater basin have caused concern about possible saltwater intrusion into the coastal freshwater aquifer. To give advance warning of such intrusion, two multipiezometer wells were installed along the coast, about half a mile and 1 mile from the pumping...
A proposed U.S. resource classification system
Charles D. Masters
1979, Open-File Report 79-1553
Energy is a worldwide problem calling for worldwide communication to resolve the many supply and distribution problems. Essential to a communication problem is a definition and comparability of elements being communicated. The U.S. Geological Survey, with the cooperation of the U.S. Bureau of Mines and the U.S. Department of Energy,...
Elevations and discharges produced by a simulated flood wave on the lower Sabine River, Louisiana and Texas, caused by a theoretical dam failure
Braxtel L. Neely, Gloria J. Stiltner
1979, Open-File Report 79-678
The Toledo Bend Reservoir is located on the lower Sabine River between Louisiana and Texas. The objective of this study was to calculate the flood wave that would result from the theoretical failure of 25 percent of Toledo Bend Dam and route the wave downstream to Orange, Tex. Computations assumed...
Near-surface heat flow in Saline Valley, California
Charles W. Mase, S.P. Galanis, Robert J. Munroe
1979, Open-File Report 79-1136
With the exception of values from one borehole drilled at Palm Spring and three boreholes drilled around Saline Valley dry lake, eight new heat-flow values in Saline Valley, California, are within or somewhat below the range one would expect for this region of the Basin and Range heat-flow province. The...
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...
Titaniferous magnetite in the layered intrusive complex at Lakathah, Kingdom of Saudi Arabia
Conrad Martin, Ralph Jackson Roberts, D. B. Stoeser
1979, Open-File Report 79-1210
The Lakathah layered intrusive complex about 90 km east of Qunfudhah contains significant resources of low-grade titanium-bearing rock. The complex is about 10 km in diameter and consists of three principal units: an outer syenite ring, an intermediate diorite-gabbro zone, and a central pyroxenite-hornblendite core. The principal mineralization zone is...
