Abstract:

THe optimal best flood-damage-mitigation plan, from the national economic development standpoint, is the plan that yields the maximum net economic benefit consistent with environmental, institutional, social, and financial requirements. To identify this optimal plan, candidate measures for various locations in a catchment are proposed, and plans that include combinations of those measures are evaluated and compared. Hydrologic Engineering Center HEC computer programs can be used for this plan evaluation. All possible combinations of the measures can be evaluated and compared but such total enumeration is time-consuming and costly. A branch-and-bound procedure is a more efficient approach. With this procedure, the entire set of plans is divided repeatedly into subsets which are evaluated in the detail necessary to determine that the optimal plan is not in the subset or to identify it if it is. This document describes, in detail, the procedure for selecting the optimal combination of flood-damage-mitigation measures and illustrates how the HEC programs can be used in the analysis. An example is presented in which the optimal plan is determined for a hypothetical catchment. Author
