Input and output shapefiles used in the hydraulic modeling for the Clear Fork Mohican River and Cedar Fork in Richland County, Ohio

Digital flood-inundation maps for an 18.6-mile (mi) reach of the Clear Fork Mohican River that extends approximately from 100 feet upstream from Gass Road near Lexington, Ohio to 700 feet downstream from Benedict Road in Butler , Ohio, were created by the U.S. Geological Survey (USGS) in cooperation with the Muskingum Watershed Conservancy District as part of a Federal Emergency Management Agency (FEMA) Flood Insurance Study (FIS). The flood-inundation maps show estimates of the areal extent corresponding to the 1% and 0.2% annual-exceedance probability floods. Flood profiles were computed for the stream reach by means of the one-dimensional step-backwater model HEC–RAS. The model was calibrated by using the current stage-discharge [...]
