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...
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...

Water-quality indices for specific water uses
J.D. Stoner
1978, Circular 770
Water-quality indices were developed to assess waters for two specific uses--public water supply and irrigation. The assessment for a spcific water use is based on the availability f (of (1) a set of limits for each water quality property selected, (2) a rationale for selection, and (3) information that permits...
Flow characteristics of streams in Tutuila, American Samoa
Iwao Matsuoka
1978, Water-Resources Investigations Report 78-103
The island of Tutuila is the economic and population center of American Samoa. It lies in the tropics and rainfall is abundant. Annual rainfall at upper Faga'alu reservoir averaged 207 inches during the period 1904-75. Available records show that altitude is a significant factor affecting the amount of rainfall. Small,...

1978, Water-Resources Investigations Report 78-34
This map depicts the approximate top of the rock that composes the Floridan aquifer. The contours represent the elevation of the top of the Floridan aquifer to mean sea level. Rock units recognized to be part of the Floridan aquifer are limestone and dolomite ranging from middle Eocene to early...
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...
Source, use, and disposition of water in Florida, 1975
Stanley D. Leach
1978, Water-Resources Investigations Report 78-17
On the average, 18,420 million gallons of water was withdrawn for use in Florida each day in 1975--an increase of 3,107 million gallons per day (Mgal/d) rate since 1970. The 1975 daily total was made up of 11,502 million gallons of saline water and 6,918 million gallons of freshwater. The...

Monthly fluctuations in the quality of ground water near the water table in Nassau and Suffolk Counties, Long Island, New York
Brian G. Katz, Stephen E. Ragone, Juli B. Lindner-Lunsford
1978, Water-Resources Investigations Report 78-41
Water samples from wells in a sewered and an unsewered suburban area and an unsewered rural area on Long Island, N.Y. were collected and analyzed monthly from August 1975 to July 1976 to determine the concentrations of chloride, sulfate, and nitrate in ground water near the water table. Short-term and...
Dissolved-solids budget of Lake Okeechobee, Florida, October 1964 to September 1974
David V. Maddy
1978, Water-Resources Investigations Report 77-97
Lake Okeechobee is a major surface-water storage facility for south Florida. A dissolved-solids budget for Lake Okeechobee was computed for Oct. 1964 to Sept. 1974, a 10-year budget period. Calculations were based on records of daily discharge, daily specific conductance measurements, and regression equations relating dissolved-solids concentrations and specific conductance....
Availability and quality of water from shallow aquifers in Duval County, Florida
Lawson V. Causey, G. G. Phelps
1978, Water-Resources Investigations Report 78-92
The shallow-aquifer system in Duval County, Fla., overlies the Florida aquifer and is composed chiefly of sand, clay, sandy clay, and limestone. Thickness of the system ranges from about 300 to 600 feet. The upper 150 feet of deposits, consisting of the water-table and shallow-rock zones, are the most dependable...
