FLOOD DAMAGE ANALYSIS (HEC-FDA)
1. Purpose and objectives
The program computes expected annual damage (commonly referred to as average annual damage) which is needed in the economic evaluation of flood plain management plans. Risk and uncertainty can also be evaluated.
Damage may be computed in two modes: (1) the expected annual damage obtained by integrating the damage v. the exceedance probability function and (2) the equivalent annual flood damage associated with a particular discount rate and period of analysis. The computations are made for each
Graphic user interface prompts users for input. The data required for
damage calculations by EAD consists of sets of the following for each
floodplain management plan: exceedance probability vs. flows or stages, stages vs. flow for rating curves, and stage vs. damage.
The computed values for damage are displayed by damage category. There
is also a summary table of the results for the base year and most likely
future condition year. Extensive graphics are provided.
5. Operational requirements and restrictions
The program has a windows graphical user interface and is operational on Windows 95, 98, NT and UNIX.
6. Form of presentation
CD or download from www.hec.usace.army.mil . Support documentation consists of a user manual, which is also on the CD and website.
7. Operational experience
Extensive -- public agencies and private consultants, mostly U.S., some foreign.
8. Originator and technical support
The Hydrologic Engineering Center, HEC, U.S. Army Corps of Engineers.
10. Conditions on use
Internet download is free. A standard handling fee is charged for the CD and documentation.
