Temperature in streams of New Mexico for the period October 1964 to September 1969
Ralph W. Clement
1978, Water-Resources Investigations Report 78-140
Harmonic equations were developed to describe stream temperatures at 144 sites in New Mexico using periodically observed water temperatures collected from October 1964 through September 1969. The harmonic equations explained at least 80 percent of the variability at 70 of the sites. Standard errors of estimate ranged from 1.3 to...
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...
Ground-water quality near the northwest 58th Street solid-waste disposal facility, Dade County, Florida
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...

Henry G. Healy
1978, Water-Resources Investigations Report 78-95
An estimated 15,000 uncontrolled flowing wells, many discharging water of poor quality are wastefully discharging about 790 million gallons per day by surface and internal flow. Internal flow in principal problem areas have been identified in Brevard, Charlotte, Clay, De Soto, Duval, Flagler, Glades, Hendry, Hillsborough, Lee, Manatee, Martin, Nassau,...
Nitrogen, phosphorus, organic carbon, and biochemical oxygen demand: in Florida surface waters, 1972
Matthew I. Kaufman, J.E. Dysart
1978, Water-Resources Investigations Report 78-43
Water samples were collected during spring and autumn 1972 from about 100 surface-water sites in Florida. The samples were analyzed for the plant nutrients, nitrogen and phosphorus. In most waters, nitrogen concentrations are less than 2.0 milligrams per liter as nitrogen, and organic nitrogen is dominant. Median total nitrogen concentration...
Interpretation of well logs in a carbonate aquifer
L.M. MacCary
1978, Water-Resources Investigations Report 78-88
This report describes the log analysis of the Randolph and Sabial core holes in the Edwards aquifer in Texas, with particular attention to the principles that can be applied generally to any carbonate system. The geologic and hydrologic data were obtained during the drilling of the two holes, from extensive...
Ten-year low mean monthly discharge determinations for ungaged streams near waste-stabilization ponds in Wisconsin
Stephen J. Field
1978, Water-Resources Investigations Report 78-49
Communities that use fill-and-draw waste-water treatment lagoons or waste-stabilization ponds are required to discharge during the spring and fall of the year at a rate that does not exceed the assimilative capacity of the receiving stream. The 10-year low mean monthly discharge (MMQ10) for October, November, April, and May for...

Sediment discharge from highway construction near Port Carbon, Pennsylvania
Robert E. Helm
1978, Water-Resources Investigations Report 78-35
The effects of highway construction on suspended-sediment loads were studied in the upper reaches of the Schuylkill River basin, Schuylkill County, Pennsylvania, from April 1975 to March 1977. From March 1975 to October 1976, 4.3 miles of State Route 209 was relocated through the upper reaches of the basin, a...
Digital-model simulation of the glacial-outwash aquifer, Otter Creek-Dry Creek basin, Cortland County, New York
O. J. Cosner, J. F. Harsh
1978, Water-Resources Investigations Report 78-71
The city of Cortland, New York, and surrounding areas obtain water from the highly productive glacial-outwash aquifer underlying the Otter Creek-Dry Creek basin. Pumpage from the aquifer in 1976 was approximately 6.3 million gallons per day and is expected to increase as a result of population growth and urbanization. A...
Ground-water storage in the Johnson Valley area, San Bernardino County, California
James J. French
1978, Water-Resources Investigations Report 77-130
The Mojave Water Agency includes several desert basins where ground water in storage is many times as great as the average annual recharge. The Johnson Valley area in San Bernardino County, Calif., was evaluated for (1) the quantity of ground water in storage, (2) the chemical quality of the ground...
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...
Transit losses and traveltimes of reservoir releases along the Arkansas River from Pueblo Reservoir to John Martin Reservoir, southeastern Colorado
Russell K. Livingston
1978, Water-Resources Investigations Report 78-75
The need for accurate information regarding the transit losses and traveltimes associated with releases from Pueblo Reservoir has been stimulated by construction of the U.S. Bureau of Reclamation's Fryingpan-Arkansas Project and a proposed winter-water storage program in Pueblo Reservoir. To meet this need, the U.S. Geological Survey, in cooperation with...

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...
