Colorado Flood Database
Study Area: Colorado
Period of Project: October 2010 - September 2016
Project Number: RE00EDY
Project Chief: Michael Kohn, P.E.
Cooperator: Colorado Department of Transportation
The accuracy of flood-frequency estimates can be greatly improved when historical flood information is included with systematically collected flood data (Interagency Committee on Water Data, 1982). Although many reports contain flood information for streams in Colorado, there is no centralized repository for this information, making it difficult to access flood data. Prior to the completion the Web-based flood database, much of the historical flood information for Colorado was stored in numerous published and unpublished reports and files in local, State, and Federal government agencies and the offices of engineering firms and universities. Although considerable research has been conducted using historical flood information in flood-frequency analyses, this information is often underutilized because of the uniqueness of each site and a lack of knowledge of each site’s location. Having an easy-to-use, Web-based geodatabase of historical flood and paleoflood information with links to sources of flood data allows engineers and water-resource managers to fully use these data leading to improved flood-frequency estimates of the largest floods in Colorado.

- To develop a Web-based geodatabase accessible using an Environmental Systems Research Institute ArcGIS map interface for flood information that will facilitate easier access to this information for the compilation of flood data and result in improved flood frequency estimates in Colorado;
- To include the following data sources of flood information: indirect discharge measurements stored in U.S. Geological Survey offices, floods from indirect discharge measurements referenced in U.S. Geological Survey reports, paleoflood studies from peer-reviewed journal articles, and the U.S. Geological Survey National Water Information System peak-streamflow database.
