HAZUS-MH FAQs: Flood Model Operation and Analysis

What should I do if I get Failed Reaches in Hydraulics?

At the end of running the Hydraulics (Delineate Floodplain) analysis, a new layer, Failed Reaches, designated by the color purple might appear.  To remove them, rerun the Hydraulic analysis.  The runtime will be shorter since HAZUS caches and skips over the "good" reaches and analyzes only the failed reaches.  Several runs might be needed to remove all of the problem reaches.

For additional information, the HAZUS User's Manuals and guidance materials are available for download from the HAZUS Resources on this site.
