Peak flow rate and recession-curve characteristics of a karst spring in the Inner Bluegrass, central Kentucky
G.K. Felton, J.C. Currens
1994, Journal of Hydrology (162) 99-118
The flow rate at the terminal spring of a 1929 ha karst ground-water catchment has been continuously monitored for 2 years, and 108 identifiable events were analyzed. The peak flow rates followed a beta frequency distribution with parameters α = 0.365 and γ = 1.135. Events were separated into high-flow and low-flow. High-flow events...
Documentation of a computer program to simulate transient leakage from confining units using the modular finite-difference, ground-water flow model
S. A. Leake, P.P. Leahy, A. S. Navoy
1994, Open-File Report 94-59
Transient leakage into or out of a compressible fine-grained confining unit results from ground- water storage changes within the unit. The computer program described in this report provides a new method of simulating transient leakage using the U.S. Geological Survey modular finite- difference ground-water flow model (MODFLOW). The new...

Methods for estimating magnitude and frequency of floods in the southwestern United States
B. E. Thomas, H. W. Hjalmarson, S. D. Waltemeyer
1994, Open-File Report 93-419
Methods have been developed for estimating magni- tude and frequency of floods at gaged and ungaged sites on streams in the southwestern United States. Estimating equations for ungaged sites that apply to small drainage basins were developed by transferring information from ungaged sites using techniques such as multiple regression...
Using analytical services at the National Water Quality Laboratory
L.K. Pratt
1994, Open-File Report 94-26
The National Water Quality Laboratory (NWQL) offers a variety of analytical services for the determination of constituents in samples of water, sediment, and biological material. As technology has advanced, many new methods have been introduced but not always incorporated into plans and schedules developed in the districts. The strengths and...

Rainfall, evapotranspiration, total soil-water potential, and soil-water content at a sagebrush site and a replacement-vegetation site near Fort Defiance, Arizona, 1989-91
C. L. Thomas
1994, Open-File Report 94-43
The Navajo Nation Forestry Department established a growth of four species of native grasses and two species of native shrubs on formerly sagebrush- covered land about 6 miles north of Fort Defiance, Arizona. The native grasses and shrubs grew under conditions of natural precipitation and soil fertility. This provided alternate...
Ground-water quality for Grainger County, Tennessee
J.D. Weaver, A.R. Patel, A.C. Hickey
1994, Open-File Report 93-365
The residents of Grainger County depend on ground water for many of their daily needs including personal consumption and crop irrigation. To address concerns associated with ground-water quality related to domestic use, the U.S. Geological Survey collected water samples from 35 wells throughout the county during the summer 1992....

Gravitational stresses in long symmetric ridges and valleys in anisotropic rock
E. Pan, B. Amadei, W. Z. Savage
1994, International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts (31) 293-312
The effect of topography and rock mass anisotropy on gravitational stresses in long isolated symmetric ridges and valleys is modeled using an analytical method proposed earlier by the first two authors. The rock mass deforms under a condition of plane strain. A parametric study is presented on the effect of...
Stimulated anoxic biodegradation of aromatic hydrocarbons using Fe(III) ligands
Derek R. Lovley, J.C. Woodward, F. H. Chapelle
1994, Nature (370) 128-131
Contamination of ground waters with water-soluble aromatic hydrocarbons, common components of petroleum pollution, often produces anoxic conditions under which microbial degradation of the aromatics is slow. Oxygen is often added to contaminated ground water to stimulate biodegradation, but this can be technically difficult and expensive. Insoluble Fe(III) oxides, which are...
Overview of environmental and hydrogeologic conditions at King Salmon, Alaska
C. F. Waythomas
1994, Open-File Report 94-323
The Federal Aviation Administration is conducting preliminary environmental assessments at most of its present or former facilities in Alaska. Information about environmental conditions at King Salmon, Alaska are presented in this report. This report gives an overview of the geology, hydro- logy, and climate of the King Salmon area...

1994, Open-File Report 94-80
A map of the September 1993 potentiometric surface of the intermediate aquifer system in west- central Florida depicts water levels for the annual high water-level period. Water levels measured in September 1993 were generally below those reported for September 1992. In 134 wells with paired measurements, the September 1993 level...
Hydrogen peroxide as a fungicide for fish culture
V. K. Dawson, J.J. Rach, Theresa M. Schreier
1994, Bulletin of the Aquaculture Association of Canada (94) 54-56
Antifungal agents are needed to maintain healthy stocks of fish in the intensive culture systems currently employed in fish hatcheries. Malachite green has been the most widely used antifungal agent; however, its potential for producing teratology in animals and fish precludes further use in fish culture. Preliminary studies...

In Montana, Wyoming, North and South Dakota, and Minnesota, Cretaceous strata are preserved in the asymmetric Western Interior foreland basin. More than 5,200 m (17,000 ft) of Cretaceous strata are present in southwestern Montana, less than 300 m (1,000 ft) in eastern South Dakota. The asymmetry resulted from varying rates...
