Effects of the Drought of 1980-81 on Streamflow and on Ground-Water Levels in Georgia
From purpose and scope: This report examines and discusses the severity, areal extent, and duration of the 1980-81 drought in Georgia. This drought produced the lowest rates of streamflow since 1954 in most areas of the State and the lowest since 1925 in some areas.

Estimating Generalized Flood Skew Coefficients for Michigan
From purpose and scope: The purpose of this report is to compare and evaluate four methods of estimating flood-frequency skew coefficients for Michigan. These methods are based on use of (1) the generalized skew map of the United States, (2) maps showing lines of equal mean skew of Michigan, (3) mean regional station skews, and (4) skew-prediction equations.

From introduction: At the request of the U.S. Bureau of Indian Affairs, the U.S. Geological Survey conducted the present study to estimate natural streamflow in the Jemez River at the boundaries of the various Indian lands. Natural streamflow is defined as the streamflow that would occur if there had been no man-made changes in the hydraulic characteristics of the river basin.

Evaluation of the Effects of Lake Audubon on Ground- and Surface-Water Levels in the Lake Nettie Area, Eastern Mclean County, North Dakota
Purpose and scope: The purpose of this investigation is to describe changes in the ground-water levels and levels of surface-water bodies and to ascertain whether those changes can be ascribed to the raising of the level of Lake Audubon, or to the subsequent filling of the McClusky Canal, or both. The changes will be determined by analysis of water-level records obtained from observation wells.

Evaluation of the Response of the Big Sioux Aquifer to Extreme Drought Conditions in Minnehaha County, South Dakota
From purpose and approach of study: The purpose of this study was to use the digital-computer model developed from the previous study (Koch, 1982) to examine the effects on the aquifer of a pumping rate of 25 million gallons a day under the worst-drought conditions that occurred during 1974-78. A frequency rating was determined for the most severe low-flow condition in the Big Sioux River.

Flood Elevations for the Soleduck River at Sol Duc Hot Springs, Clallam County, Washington
Abstract: Elevations and inundation areas of a 100-year flood of the Soleduck River, Washington, were determined by the U.S. Geological Survey for the area in the vicinity of the Sol Duc Hot Springs resort, a public facility in the Olympic National Park that under Federal law must be located beyond or protected from damage by a 100-year flood. Results show that most flooding could be eliminated by raising parts of an existing dike. In general, little flood damage is expected, except at the southern end of an undeveloped airstrip that could become inundated and hazardous due to flow from s tributary. The airstrip is above the 100-year flood of the Soleduck River.

Flood-Frequency Relations for Urban Streams in Metropolitan Atlanta, Georgia
From abstract: A knowledge of the magnitude and frequency of floods is needed for the design of highway drainage structures, for establishing flood insurance rates, and for many other uses by urban planners and engineers. This report presents a method for estimating the magnitude and frequency of floods on small streams in the Atlanta, Georgia, metropolitan area.

Flood in Kansas City, Missouri and Vicinity, August 12-13, 1982
Purpose and scope: This report has been prepared to document these significant floods for future hydraulic and hydrological planning; to provide streamflow information required for orderly development of river basins where the hazard of extreme flooding exists; and to further the general hydrologic knowledge available for Missouri rivers and streams. Streamflow data in the report include peak stages and discharges, flood hydrographs, flood-crest profiles, flood volumes, and flood-frequency information. Descriptions of the storm and of the damages resulting from these floods are given.

Fortran Computer Programs to Plot and Process Aquifer Pressure and Temperature Data
From introduction: In this report, two programs have been developed for use in managing data derived from an aquifer thermal-energy storage (ATES) project being done by the University of Minnesota. Data are generated from temperature and pressure measuring devices that are read automatically by a datalogger. Up to 100 channels can be scanned every 10 seconds and recorded on magnetic tape or printed as paper output. Time period of up to several years of data may be represented on a single tape.

Front-Tracking Model for Convective Transport in Flowing Ground Water
Abstract: This report describes a finite-difference numerical model that simulates the convective transport of water or tracer particles through porous media. It can be applied to one- or two-dimensional problems involving either steady-state or transient flow. The model tracks representative water or tracer particles, initially located along specified lines, as they move in response to the ground-water velocity field. Aquifer properties may be both anisotropic and nonhomogeneous. Included in the report is a listing of the program along with input formats and test problem results. The front-tracking model provides a useful first approximation for determining the movement of solutes in an aquifer, particularly in cases where dispersion and dilution is of minor consideration.

Geohydrology of the Meadowbrook Artificial-Recharge Site at East Meadow, Nassau County, New York
Purpose and scope: The Meadowbrook artificial-recharge project, a cooperative effort between the U.S. Geological Survey and the Nassau County Department of Public Works (NCDPW) since 1975, is intended to demonstrate the feasibility of using reclaimed wastewater to replenish and improve the quality of Long Island's ground water. This report presents the results of geologic, hydrologic, and hydrochemical studies that were done at the Meadowbrook artificial-recharge site to define conditions prevailing before the start of recharge operations.

Ground-Water Contamination at Wurtsmith Air Force Base, Michigan
From introduction: The U.S. Geological Survey, at the request of the U.S. Air Force, began an investigation of geologic and hydrologic conditions at Wurtsmith Air Force Base in September 1979. The investigation was prompted by the discovery that an underground storage tank containing trichloroethylene (TCE) had leaked, contaminating Base water-supply wells. Subsequent information suggested that the trichloroethylene had moved off-Base.
