CWMS has the capability to compute flood damages reduced by reservoirs and levees from a CAVI forecast using HEC-FIA. Each year USACE districts are required to report the Annual Flood Damages Reduced (AFDR) by each of their their flood risk reduction projects. AFDR is a monetary estimate that represents the amount of property damages that were averted by USACE reservoirs and levees. In the most basic sense, computing the flood damages reduced for an event involves comparing damages for the regulated (with project) condition to the unregulated (without project) condition. The methodology to compute flood damages reduced can vary drastically and selection of the best suited method is dependent on the complexity of the system, the characteristics of the watershed, and level of detail desired. This type of analysis requires technical expertise in hydrology, hydraulics, and economics to produce and interpret results. Refer to the Guide to Computing Annual Flood Damages Reduced documentation for more information on how to set up and run CWMS models to compute AFDR.
