The traditional approach of the U.S. Army Corps of Engineers to flood damage reduction studies is compared to risk-based analysis, a method of performing studies in which uncertainty in technical data is explicitly taken into account. Use of the risk-based method results in explicit consideration of uncertainty in estimated flow-blood frequency, flood stage, and flood damage, and hence in project flood damage reduction benefits. Several examples are cited.
