Description:
From abstract: A study was made of the White River between Lake Sequoyah and Beaver Lake to determine the quality of the river under existing conditions and how the effluent from the Fayetteville municipal wastewater-treatment plant, the only point source discharger of waste effluent to the river, affects this quality.

Description:
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 applic…

Description:
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 repo…

Description:
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 …

Description:
This report includes two maps of the same location, one describing water-level contour, well depth in which depth to water was measured, the other describing well from which water sample was collected and irrigated areas. It includes a letter from the district chief of the United States Department of the Interior to users of the geological survey hydrologic data.
Description:
From abstract: The purposes of this report are to determine the low-flow characteristics in the Red Cedar River Basin, where surplus water may be diverted, and to present methods to determine low-flow characteristics at additional sites.
Description:
From abstract: This report examines and compares "the quality of water discharging from a strip-mined basin and a relatively unmined basin on the Cumberland Plateau in Tennessee." They determine that "the chemical and aesthetic quality of these waters will directly affect the chemical and aesthetic quality of the water flowing through a proposed national river and recreation area." It includes maps, graphs, and tables.
Description:
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 t…

Description:
From purpose and scope: There are two principal purposes for this study. The first is to describe the hydrogeologic system of the study area. The second is to develop and demonstrate a capability for evaluating, quantitatively, the effects of different management alternatives on water levels and on streamflow in the study area.
Description:
From purpose and objectives: The purpose of this report is to summarize the hydrologic investigation. The study objective was to provide data and a limited interpretation of surface- and ground-water flow systems.
Description:
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.
Description:
From abstract: This report presents chemical-quality data collected from May 1980 to January 1981 at several locations within the Delaware River estuary and selected New Jersey tributaries.
Description:
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).
Description:
This report uses a digital model to predict the projected increase in ground-water use caused by a population influx for September 1976 in Cortland, New York. It contains maps, tables, and other figures.
Description:
From purpose and scope: One of the objectives of the ongoing U.S. Geological Survey investigation of the Loxahatchee River estuary is to provide baseline information on the estuary. This map report was prepared to fulfill part of this objective. It provides information on bathymetry, hydrology, and benthic sediment and biota.

Description:
From purpose and scope: The purposes of this investigation are (1) to define the ground-water system in the Arikaree Formation, (2) to determine the hydrologic cause-and-effect relationships resulting from the current ground-water development, and (3) to provide a means of indicating the hydrologic effect of future ground-water development.
Description:
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.
Description:
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.

From introduction: In 1978 the U.S. Geological Survey began a 4-year study of aquifers in the northern Great Plains. The purpose of this map, which is a product of that study, is to show the cumulative thickness of sandstone in the Swift Formation.

Description:
From introduction: The objectives of the streambed-materials rials reconnaissance were to: (1) provide baseline concentrations of selected elements sorbed on streambed materials and (2) determine the effect of land use and surficial geology on the concentration of selected elements on streambed materials from southwestern Indiana.
Description:
From abstract: This report presents an evaluation and a list of "potential problems associated with increases in pumpage and urban development" in the Memphis area of Tennessee. These problems include "lowered water levels, contamination of the aquifers, and land subsidence."
