Dam Failure Inundation Mapping is a valuable tool to increase community awareness of the risks should a dam fail. Dams have different hazard ratings depending upon the condition of the dam and/or the impact downstream should the dam fail. Hazard creep is a term used for a condition where the hazard rating associated with a dam increases due to development occurring in the hydraulic shadow of a dam.
Several states have developed websites with mapping that shows the inundation boundary based upon the hypothetical failure of dams in their state. Inundation maps are used to develop emergency action plans and the maps are intended to provide general information for emergency planning and response.
This webinar will present information on hazard creep and highlight websites developed by the State of Maryland and the State of California.
