Computation of water-surface profiles in open channels
Jacob Davidian
1984, Techniques of Water-Resources Investigations 03-A15
The standard step-backwater method of computing water-surface profiles is described in this chapter. The hydraulic principles and assumptions are reviewed, and the field data requirements are described. Certain special cases of backwater curves and certain special field conditions are discussed in detail. The technique is used to establish or extend...

Effects of storm-water runoff on water quality of the Edwards Aquifer near Austin, Texas
Freeman L. Andrews, Terry L. Schertz, Raymond M. Slade Jr., Jack Rawson
1984, Water-Resources Investigations Report 84-4124
Analyses of samples collected from Barton Springs at approximately weekly Intervals and from Barton Creek and five wells in the Austin area during selected storm-runoff periods generally show that recharge during storm runoff resulted in significant temporal and area! variations in the quality of ground water in the recharge zone...
Potentiometric surface of the upper Floridan Aquifer in the St. Johns River Water Management District and vicinity, Florida, September 1984
George R. Schiner, Eugene C. Hayes
1984, Open-File Report 84-865
This map shows the potentiometric surface of the Upper Floridan aquifer in the St. Johns River Water Management District and vicinity for September 1984. The Upper Floridan aquifer is the principal source of potable water in the area. Water-level measurements were made on approximately 1,000 wells and on several springs....
Ground-water levels in Arkansas, spring 1984
Joe Edds
1984, Open-File Report 84-711
This report contains about 680 ground-water level measurements made in observation wells in Arkansas in the spring of 1984. In addition, the report contains well hydrographs relating to the alluvial aquifer and the Sparta Sand and Memphis Sand aquifers, the most important aquifers with respect to ground-water availability and use...

Ground-water level data and preliminary potentiometric-surface maps, Yucca Mountain and vicinity, Nye County, Nevada
J. H. Robison
1984, Water-Resources Investigations Report 84-4197
The report contains a table of ground-water level data and two preliminary potentiometric-surface maps for the Yucca Mountain area. The water-level surface shown on the maps generally represents water-table (unconfined) conditions. The water table in the Yucca Mountain area occurs in ash-flow and air-fall tuffs of tertiary age. West of...

Mapping of forested wetland: Use of seasat radar images to complement conventional sources
John L. Place
1984, Open-File Report 84-312
Distinguishing forested wetland from dry forest using aerial photographs has been handicapped because photographs often do not reveal the presence of water below the tree canopies. Images obtained during the summer months of 1978 by the Seasat satellite's L-band (23-cm) radar reveal forested wetland as patterns of high radar reflection in the Atlantic coastal...
