D.A. Olin
1985, Water-Resources Investigations Report 84-4191
Methods are presented to estimate flood magnitude for selected recurrence intervals for urban and rural streams with drainage areas from 1 to 22,000 square miles. Seven hydrologic areas were delineated and regression equations were developed for six areas. Hydrologic data could not be regionalized for the seventh area. Drainage area...

F. R. Twenter, T. R. Cummings
1985, Water-Resources Investigations Report 85-4110
Migration of mineralized water from abandoned subsurface coal mines in Monitor and Williams Townships was thought by many residents to have affected the quality of domestic ground-water supplies in the area. To investigate the possibility, wells were installed to obtain geologic data and water samples for chemical analysis; analysis also...

1985, Water-Resources Investigations Report 85-4299
A digital model of two-dimensional groundwater flow was used to estimate the hydraulic properties of the Edwards Aquifer in a 151 sq mi area near Austin, Texas. The transmissivity, hydraulic conductivity, and specific yield were estimated for the part of the aquifer that discharges at Barton Springs in Austin. The...
Development and calibration of a two-dimensional digital model for the analysis of the ground-water flow system in the San Antonio Creek Valley, Santa Barbara County, California
Peter Martin
1985, Water-Resources Investigations Report 84-4340
A two-dimensional finite-difference model was used to simulate ground-water flow conditions in San Antonio Creek valley. The model was calibrated to simulate steady-state conditions as approximated by ground-water conditions in 1943 and transient conditions during the period 1944-77. The transmissivity of the aquifer and the vertical hydraulic conductivity of the...
Feasibility of artificial recharge to the 800-foot sand of the Kirkwood Formation in the coastal plain near Atlantic City, New Jersey
J.E. May
1985, Water-Resources Investigations Report 85-4063
Renewed development of the Atlantic City area since the mid-1970 's has increased the demand for water. Increased pumpage from the 800-foot sand of the Kirkwood Formation has reversed an antecedent water-level recovery in this aquifer, thus reducing water in storage and increasing the potential for saltwater intrusion. Practicable approaches...
The flood of December 1982 and the 100- and 500-year flood on the Buffalo River, Arkansas
B.L. Neely
1985, Water-Resources Investigations Report 85-4192
Flood profiles, peak discharges, and stages were determined for the December 1982, the 100-year, and the 500-year floods at 17 sites along the Buffalo River, Arkansas. Typical synthetic stage hydrographs for the 100- and 500-year floods were determined for each site. Flow duration data for gaging stations at St. Joe...
Techniques for estimating flood peak discharges for unregulated streams and streams regulated by small floodwater retarding structures in Oklahoma
R. L. Tortorelli, D. L. Bergman
1985, Water-Resources Investigations Report 84-4358
Statewide regression relations for Oklahoma were determined for estimating peak discharge of floods for selected recurrence intervals from 2 to 500 years. The independent variables required for estimating flood discharge for rural streams are contributing drainage area and mean annual precipitation. Main-channel slope, a variable used in previous reports, was...
Availability and quality of ground water in the Piedmont Province of Virginia
John Duane Powell, Joseph M. Abe
1985, Water-Resources Investigations Report 85-4235
The Piedmont Province of Virginia has an ample supply of groundwater, (perhaps as much as 1.5 billion gallons are in storage per sq mi) generally suitable for domestic and small supply needs. The source of this groundwater is precipitation, which is stored in the pore spaces of the regolith and...

Calibration procedure for a daily flow model of small watersheds with snowmelt runoff in the Green River coal region of Colorado
J. M. Norris, R. S. Parker
1985, Water-Resources Investigations Report 83-4263
A calibration procedure was developed for the U.S. Geological Survey 's Precipitation-Runoff Modeling System for watersheds in which snowmelt is the major contributor to runoff. The model uses daily values of air temperature and precipitation as input and the output is mean daily discharge. The procedure appears sufficient to calibrate...
