From abstract: Tests were conducted on a 1:40-scale model of Big Creek to investigate the hydraulic performance of a proposed floodway channel and a section of a modified channel.

This report presents findings on "ground-water well inventory, water level measurements, and water-quality samplings" taken in Geauga County, Ohio. It includes maps showing potentiometric-surface changes.

From introduction: In 1975 a project was begun to provide information on several aspects of coal hydrology in Ohio. The first phase was a reconnaissance of water-quality conditions in coal-mining regions. Phase one had two primary objectives; to document the occurrence of certain inorganic and organic constituents in waters of the coal-mining regions and to determine if the concentrations of those constituents were related to coal mining. The second phase of the project was a more detailed study of four basins sampled during the first phase.

From introduction: This report is part of an overall study to model the flow and to describe the water-quality characteristics of the glacial outwash aquifer in part of the Scioto River basin. The purpose of this report is to describe the development of a transient-state digital-computer model and the simulated water-level resulting from anticipated withdrawal by up to six new municipal wells.

From introduction: The purpose of this report is to provide meteorologic and hydrologic data in more detail than could be given in the monthly and annual summary publications of the National Oceanic and Atmospheric Administration (NOAA), the Ohio Department of Natural Resources, or the USGS.

From introduction: This report summarizes estimates of Ohio water use for 1975. These figures are revisions of data which were compiled by the U.S. Geological Survey in the Circular, "Estimated Water Use in the United States, 1975" (Murray and Reeves, 1976). In that circular, water-use figures were aggregated for the state of Ohio as a whole, and for the U.S. Water Resources Council's Great Lakes and Ohio River hydrologic regions.

Abstract: A glacial outwash aquifer of about 70 square miles in the Scioto River valley southeast of Columbus, Ohio, was modeled as a potentially major source of water. The model was constructed from available hydrologic data: Records of precipitation, well hydrographs, well logs, two ground-water level surveys, and analyses of six aquifer tests. Utilizing this array of data, water levels determined from a series of steady-state simulations of different hydraulic conductivity distributions were calibrated against measured (December 1977) ground-water levels. The simulations that provided the best matches used two hydraulic conductivity distributions: One was an areally varying hydraulic conductivity distribution; the other an areally uniform hydraulic conductivity (40 feet per day) distribution. After these more probable hydraulic conductivity distributions were found, they were utilized in steady state maximal pumping simulations. The maximal well-field yield of these simulations was 20.5 million gallons per day for the areally varying hydraulic conductivity distribution, and 11.3 million gallons per day for the areally uniform hydraulic conductivity. Sensitivity of well yield to changes in well position and streambed leakance changes was investigated also.

From introduction: The purpose of the overall study is to determine impacts of strip mining on local hydrologic systems.

Abstract: Reaeration coefficients of the North Fork Licking River at Utica, Ohio were measured by the radioactive-tracer method. The tests were conducted on a 2.1-mile reach on September 23 and October 7, 1981, during low-flow conditions. Krypton-85 gas and tritium were the radioactive tracers, which were used in conjunction with rhodamine-WT dye. The reaeration coefficients determined on September 23 were 3.09 days^-1 (subreach 1-2) and 3.32 days^-1 (subreach 2-3). On October 7, the values were 2.04 days^-1 and 2.23 days^-1 respectively.
