Federal Guidelines for Inundation Mapping of Flood Risks Associated with Dam Incidents and Failures (FEMA P-946)
{{{author}}}, {{{date}}}
The purpose of this document is to provide dam safety professionals with guidance on how to
prepare dam breach inundation modeling studies and conduct mapping that can be used for
multiple purposes, including dam safety, hazard mitigation, consequence evaluation, and
emergency management including developing EAPs. This guidance is intended to provide a
consistent approach that can be applied across the country... Topics
include conducting breach assessments, methods for estimating breach parameters and
generating breach hydrographs, downstream inundation modeling, and generation of consistent
inundation maps. This guidance document is intended to aid in the areas of dam safety, hazard
mitigation planning, consequence and loss estimation, and emergency management.
