摘要

This paper describes a consequence estimation approach that is applied to dam break flood modeling studies being conducted by the U.S. Army Corps of Engineers (USACE) Modeling, Mapping, and Consequence (MM&C) Production Center in support of the USACE Dam Safety Program and the USACE Critical Infrastructure Protection and Resilience Program (CIPR). Focus will be on methodology and application of the Hydrologic Engineering Center's Flood Impact Analysis Model (HEC-FIA), which provides capabilities to efficiently estimate various consequences for a specific flood event.rnHEC-FIA is a stand-alone, GIS-enabled model for estimating flood impacts due to a specific flood event. The software tool can generate required economic and population data for a study area from readily available data sets and use those data to compute urban and agricultural flood damage, area inundated, number of structures inundated, population at risk and loss of life. All damage assessments in HEC-FIA are computed on a structure-by-structure basis using inundated area depth grids.rnWhile the focus of this paper is on estimating life loss for dam failure, the approach described herein is also applicable for levee safety risk assessments. HEC-FIA is the consequence engine in HEC's new Flood Risk Management tool (HEC-FRM) that is being developed to facilitate a comprehensive system-wide risk assessment for levees.
