Paleoflood Investigations to Improve Flood-Frequency Estimates for Eastern Colorado

The peak-streamflow regional-regression equations (PSRREs) in the Plains hydrologic region in eastern Colorado have the largest uncertainty of any hydrologic region in Colorado. Reliable peak-streamflow information is critical for the proper design of stream-related infrastructure, such as bridges and dams, and flood-plain inundation maps. In an effort to provide more reliable peak-streamflow...
