Man-Induced Channel Adjustment in Tennessee Streams
Preface: This report is an attempt to relate the effects of channel modifications to the resulting instabilities in the fluvial system. The primary objective is to provide the Tennessee Department of Transportation with information concerning channel stability in relation to river crossing structures. Several new analytical techniques are presented that can aid in the understanding of channel adjustment to natural and man-induced stress. The methods of analyses presented herein should be applicable to other areas with alluvial, sand-bed channels, especially in the Gulf Coastal Plains States.

Hydrogeologic and Water-Quality Characteristics of the Ironton-Galesville Aquifer, Southeast Minnesota
Introduction: The U.S. Geological Survey began a study in 1980 of the quality of water in the principal aquifers of Minnesota. The U.S. Environmental Protection Agency funded the study as part of the Underground Injection Control Program, which deals with disposal of liquid wastes beneath land surface. The initial report designated 14 aquifers in the State and provided general information about their geologic, hydrologic, and water-quality characteristics (Adolphson and others, 1981). This report, one in a series that describes individual aquifers in more detail, concerns the Ironton-Galesville aquifer.

Base Flow of Streams on Long Island, New York
Purpose and scope: The purpose of this report is to quantify the base flow of 19 continuously gaged Long Island streams during 1960-75, which includes the 1962-66 drought. These base-flow data will be used in calibrating computer models designed to predict the response of Long Island streams to hydrologic stresses such as the lowering of ground-water levels in response to large-scale sanitary sewering. The data will also be used to assess the long-term impact expected to result from storm- and sanitary-sewer systems on base flow of streams.

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.

Effects of Urbanization on Floods in the Dallas, Texas Metropolitan Area
From abstract: The analyses indicate that in a fully-developed residential area, the flood peaks with be 1.2 to 1.4 times those from an undeveloped area; and the annual direct runoff will be about double that from an undeveloped area. Data were not sufficient to determine the increase in runoff from a highly industrialized area where the effective imperviousness approaches 100 percent.

Water Resources of Hanson and Davison Counties, South Dakota
From introduction: In July 1977, the South Dakota Geological Survey and the U.S. Geological Survey began a 4-year study to evaluate the water resources and geology of Hanson and Davison Counties. The purpose of this report is to provide hydrogeologic information for future water development and planning in the counties. This study is part of an evaluation of the water resources and geology of eastern South Dakota (fig. 1).

Magnitude and Frequency of Floods in Eastern Oregon
From purpose and scope: This report describes methods for estimating the magnitude and frequency of floods at ungaged sites on streams with unregulated flow in eastern Oregon. The purpose is to provide a method to estimate flood magnitude and frequency and to present the supporting data. The report is based on data from nearly all unregulated streams (or data from regulated streams prior to their regulation) where gaging stations have been operated.

Digital Models of a Glacial Outwash Aquifer in the Pearl-Sallie Lakes Area, West-Central Minnesota
From purpose and scope: The purpose of this investigation is to 1) study the hydrologic system in a glaciated terrain typified by numerous lakes, with particular focus on the effects of lake-ground-water interchange, 2) simulate the natural system by using two digital modeling methods--areal (map view) and vertical section, and 3) evaluate the utility of the models and determine the kinds and amount of basic data needed to obtain reasonable simulations.

Ground-Water Appraisal of the Pineland Sands Area, Central Minnesota
Purpose and scope: The major purpose of this study is to evaluate the ground-water resources in the Pineland Sands area and their potential for development. The study focuses mainly on the surficial aquifer, the single most readily available source of ground water. Primary objectives of the study are (1) map the areal extent and thickness of the surficial aquifer, (2) determine its ability to transmit water to wells and define the availability of the water, (3) describe the chemical quality of the water, and (4) model the aquifer and simulate probable effects of future development. By evaluating the adequacy of the surficial aquifer, this study should aid in the proper development and management of water resources in the Pineland Sands area.
