H. C. Mattraw Jr., John E. Hull, Howard Klein
1978, Water-Resources Investigations Report 78-45
The Northwest 58th Street solid-waste disposal facility, 3 miles west of a major Dade County municipal water-supply well field, overlays the Biscayne aquifer, a permeable, solution-riddled limestone which transmits leachates eastward at a calculated rate of 2.9 feet per day. A discrete, identifiable leachate plume has been recognized under and...
Evaluation of thermograph data for California streams
J.T. Limerinos
1978, Water-Resources Investigations Report 78-66
Statistical analysis of water-temperature data from California streams indicates that, for most purposes, long-term operation of thermographs (automatic water-temperature recording instruments) does not provide a more useful record than either short-term operation of such instruments or periodic measurements. Harmonic analyses were made of thermograph records 5 to 14 years in...

Magnitude and frequency of flooding on the Myakka River, Southwest Florida
K.M. Hammett, J.F. Turner Jr., W. R. Murphy Jr.
1978, Water-Resources Investigations Report 78-65
Myakka River is a coastal stream that drains approximately 550 square miles in southwest Florida. Under natural conditions, Tatum Sawgrass, a large depression, served as a flood overflow area for the upper part of the Myakka River basin. A recently constructed (1974) dike system across the lower part of Tatum...
Appraisal of shallow ground-water resources and management alternatives in the Upper Peace and Eastern Alafia River Basins, Florida
C. B. Hutchinson
1978, Water-Resources Investigations Report 77-124
In southwest Florida, the shallow aquifer system underlying the 1,250-square-mile upper Peace and eastern Alafia River basins is a relatively untapped source of supply. The aquifer system ranges between 50 and 300 feet thick and is composed of a surficial sand unit underlain by a limestone unit. Sand and clay...

1978, IMAP 1111
Two principal physiographic provinces of Mars are represented in the Aeolis quadrangle: (1) Elysium Planitia in the north is part of a broad planet-encircling belt of relatively young lowland plains, and (2) cratered highlands in the south consist<span...
Quantitative hydrogeology of the Upper Republican Natural Resources District, southwest Nebraska
Eric G. Lappala
1978, Water-Resources Investigations Report 78-38
Ground-water use for irrigation from the Ogallala Formation }'as in-creased rapidly in the Upper Republican Natural Resources District in southwest Nebraska. Water levels declined as much as 16 feet between 1952 and 1975. Discharge of the aquifer to streams was reduced by as much as 19 percent between 1967 and...
An analysis of stream temperatures, Green River Basin, Wyoming
H. W. Lowham
1978, Water-Resources Investigations Report 78-13
A method for estimating temperatures of streams in the Green River basin, Wyoming, utilizes a regional model for estimating mean daily temperatures of streams at unmeasured sites. The regional model was developed by describing annual temperature patterns at 43 measured sites and by applying the harmonic function T = M...
Preliminary appraisal of the geohydrologic aspects of drainage wells, Orlando area, central Florida
Joel O. Kimrey
1978, Water-Resources Investigations Report 78-37
The Floridan aquifer contains two highly transmissive cavernous zones in the Orlando area: an upper producing zone about 150-600 feet below land surface; and a lower producing zone about 1,100-1,500 feet below land surface. Natural head differences are downward and there is hydraulic connection between the two producing zones. Drainage...
Unsteady solute-transport simulation in streamflow using a finite-difference model
Larry F. Land
1978, Water-Resources Investigations Report 78-18
This report documents a rather simple, general purpose, one-dimensional, one-parameter, mass-transport model for field use. The model assumes a well-mixed conservative solute that may be coming from an unsteady source and is moving in unsteady streamflow. The quantity of solute being transported is in the units of concentration. Results are...

Ground-water conditions in the Eureka area, Humboldt County, California, 1975
Michael J. Johnson
1978, Water-Resources Investigations Report 78-127
Ground-water conditions in the Eureka area, Calif., were evaluated during 1975 to determine whether significant changes had occurred since 1952, when an earlier reconnaissance was made. No major changes in water levels or water quality were noted at 1975 pumping rates. Recharge to the ground-water system compensates for both artificial...

A low-level radioactive-waste burial site, West Valley, N.Y., operated from 1963 to 1975, contains 12 refuse-filled trenches about 20 feet deep in till. Twenty-eight wells, 1.25 inch in diameter, were driven to selected depths in 11 of the 12 trenches to obtain gas and water samples for chemical and radiochemical...

Electron-microprobe study of chromitites associated with alpine ultramafic complexes and some genetic implications
M. L. Bird
1978, Open-File Report 78-119
Electron-microprobe and petrographic studies of alpine chromite deposits from around the world demonstrate that they are bimodal with respect to the chromic oxide content of their chromite. The two modes occur at 54 ? 4 and 37 ? 3 weight per cent chromic oxide corresponding to chromite designated as high-chromium...
