Sean M. Quigley 2003 Version 1.0 digital map Water-Resources Investigations Report USGS WRIR 03-4164 Columbus, Ohio U.S. Geological Survey http://water.usgs.gov/lookup/getspatial?floodregions This coverage was used to determine the flood region associated with stream basins in Ohio. This information is required to use regression equations presented by Koltun (2003). Koltun, G.F., 2003, Techniques for Estimating Flood-Peak Discharges of Rural, Unregulated Streams in Ohio: U.S. Geological Survey Water-Resources Investigations Report 03-4164 This data set was developed to facilitate determination of the flood region in which a basin's centroid is located. Information on the flood region is required to select the proper coefficient to be used in regression equations for developing flood-frequency estimates.
