Quadratic spline subroutine package
Lowell A. Rasmussen
1982, Water-Resources Investigations Report 82-41
A continuous piecewise quadratic function with continuous first derivative is devised for approximating a single-valued, but unknown, function represented by a set of discrete points. The quadratic is proposed as a treatment intermediate between using the angular (but reliable, easily constructed and manipulated) piecewise linear function and using the smoother...

Origins and distribution of saline ground waters in the Floridan Aquifer in coastal southwest Florida
W.C. Steinkampf
1982, Water-Resources Investigations Report 82-4052
Twenty-three ground-water samples from the Floridan aquifer in coastal southwest Florida show that water quality deteriorates to the south and west.

L.J. Torak
1982, Water-Resources Investigations Report 82-4025
This report describes modifications incorporated into the finite-difference model for simulation of groundwater flow in three dimensions. These modifications extend the application of this model to simulations involving head-dependent sources and sinks (i.e., rivers, evapotranspiration, and springs or drains). Other modifications are made that enhance the iterative-solution process of the...

Ground water from aquifers in all rock units is generally composed of calcium, magnesium, and bicarbonate...
Method for relating suspended-chemical concentrations to suspended-sediment particle-size classes in storm-water runoff
Joseph F. Rinella, Stuart W. McKenzie
1982, Water-Resources Investigations Report 82-39
A method has been developed to relate suspended-chemical concentrations (associated with suspended sediments) in storm-water runoff to suspended-sediment particle-size classes. These classes are based on settling velocities in quiescent native water. This method requires processing 20 liters of water having a suspended-sediment concentration greater than 500 milligrams per liter. However,...

A national water-use information program
William B. Mann, John E. Moore, Edith B. Chase
1982, Open-File Report 82-862
The U.S. Geological Survey has compiled estimates of water use every five years since 1950. These estimates have been derived from many sources, and have a wide range of accuracy. Therefore, they fall short of providing a national data base that is both current and reliable. In 1977, the Congress...
