Flood-Frequency Estimates for Ohio Streamgages Based on Data Through Water Year 2015 and Techniques for Estimating Flood-Frequency Characteristics of Rural, Unregulated Ohio Streams [open pdf - 6MB]
From the Purpose and Scope: "The purpose of this report is to describe the results of a study to (1) estimate flood-frequency characteristics for selected streamgages in Ohio and adjacent states based on data collected through water year 2015; (2) develop and present techniques for estimating flood-frequency characteristics of rural, unregulated streams in Ohio; and (3) implement the estimation techniques in the Ohio StreamStats application. This report supersedes USGS [U.S. Geological Survey] Water-Resources Investigations Report 2006-5312 (Koltun and others, 2006) in that it provides revised flood-frequency estimates for streamgages and presents new methods and equations for estimating flood-frequency characteristics of rural, unregulated streams in Ohio."
