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...

Peak-streamflow , Mean-streamflow , and Low-streamflow Equations for Western Colorado

Reliable peak-streamflow data are critical to design transportation infrastructure, such as bridges, culverts, dams, and floodplain inundation maps. At gaged sites, where sufficient long-term streamflow data have been collected, statistics can be obtained from available publications, by an analysis of available data in the U.S. Geological Survey (USGS) National Water Information System (NWIS)...
