Document Type: Proceeding Paper

Part of: Engineering Hydrology


The study described here represents a unique collaboration and cost-sharing effort between two Federal agencies: the U.S. Army Corps of Engineers (USACE) and the Federal Emergency Management Agency (FEMA). The nature and timing of this effort was made possible by the evolution of computer aided drafting (CAD) and digital mapping technology. The body of work can be partitioned into three specific objectives. The first is to generate new, high quality digital mapping of the entire Monongahela River corridor. The second is to use this mapping as the basis for a complete hydrologic reanalysis of the corridor. The final target is the development of new flood insurance study (FIS) reports for the many communities within this highly urbanized and industrialized watershed.
