The Sparta aquifer system in Mississippi
Roy Newcome Jr.
1976, Water-Resources Investigations Report 76-7
A large amount of information is available on the aquifers of Mississippi.  Reports resulting from various areal studies have described the ground-water resources of the areas concerned, but no reports dealing specifically with the entire Mississippi occurrence of individual aquifer systems have previously been prepared.  A series of "aquifer atlases"...
Middle Tertiary plutonism in the Santa Catalina and Tortolita Mountains, Arizona
S.C. Creasey, Norman G. Banks, R. P. Ashley, Ted G. Theodore
1976, Open-File Report 76-262
Recent reconnaissance geologic mapping in the Santa Catalina and Tortolita Mountains of southeastern Arizona, supplemented by new and published potassium-argon and fission-track ages, suggests that a large middle Tertiary (about 25 m.y.) composite batholith crops out extensively in both mountains. More than two-thirds of the batholith and the contiguous wallrocks...
Maps showing ground-water conditions in the Concho, St. Johns, and White Mountains areas, Apache and Navajo Counties, Arizona, 1975
R.W. Harper, T. W. Anderson
1976, Water-Resources Investigations Report 76-104
The Concho, St. Johns, and White Mountains areas cover about 2 ,300 sq mi in eastern Arizona. Ground water is present in several aquifers that are made up of one or more formations. The maps show ground-water conditions in the Coconini aquifer; in the Triassic, Cretaceous, and Tertiary rocks; and...
Hydrologic relations between lakes and aquifers in a recharge area near Orlando, Florida
William F. Lichtler, G.H. Hughes, F. L. Pfischner
1976, Water-Resources Investigations Report 76-65
The three lakes investigated in Orange County, Florida, gain water from adjoining water-table aquifer and lose water to Floridan aquifer by downward leakage. Net seepage (net exchange of water between lake and aquifers) can be estimated by equation S = AX + BY, where S is net seepage, X represents...
Sediment discharge from highway cut-slopes in the Lake Tahoe Basin, California, 1972-74
Carl G. Kroll
1976, Water-Resources Investigations Report 76-19
Streamflow and fluvial-sediment discharge data were collected at selected streams and highway gutters in the Lake Tahoe basin to determine the extent of erosion from highway cuts and to attempt to evaluate the effects of various land-treatment practices to reduce erosion.Estimate of long-term annual total-sediment discharge from six streams into...
Magnitude and frequency of floods in North Carolina, technique for estimating the magnitude and frequency of floods on natural streams in North Carolina
N.M. Jackson Jr.
1976, Water-Resources Investigations Report 76-17
Methods are provided to estimate the magnitude and frequency of floods on natural North Carolina streams with drainage areas greater than 0.5 square mile (1.3 square kilometers). For 257 gaged sites, the magnitudes of floods having recurrence intervals from 2 to 100 years are provided in tables. For ungaged sites,...
