HEC-FIA may be used in CWMS to predict the consequences associated with conditions predicted with HEC-HMS, HEC-ResSim, and HEC-RAS. There are two reports available of HEC-FIA results – Individual Structure Damage Report and Aggregated Structure Damages Report. See the HEC-FIA User's Manual for more detail on results.

Individual Structure Damage Report

This report provides information by individual structure, this information includes structure, content, car, other, total damage for each structure, depth of flooding, population at risk (day and night), percent not mobilized, percent caught evacuating, percent clear, and loss of life (day and night) information is also available for each structure. If your alternative is set to run a deterministic computation, this will display a single deterministic answer. However, if your alternative is set to run a Monte Carlo computation, this report will display the average for all of the iterations.

To view the Individual Structure Damage Report: 

  1. You must be in the Modeling tab in the Watershed Pane.
  2. To view this report make sure you have an active forecast, and at least one forecast run selected (checkbox) for viewing results (Figure 1).
  3. From the Reports tab, click Individual Structure Damage Report, the Individual Structure Damage Report will open (Figure 2).

  4. The report displays by structure the damages, flooding depth, life loss and other consequences associated with the defined forecast.
  5. Click Close, the Individual Structure Damage Report will close (Figure 2).

Aggregated Consequence Report

The Aggregated Consequence Report allows you to aggregate results by any boundary, or the impact area set you used to compute results. This functionality uses a point in polygon test on your results files, so be patient if you have many polygons or many structures, it can take a few seconds.

To view the Aggregated Consequence Report: 

  1. You must be in the Modeling tab in the Watershed Pane.
  2. To view this report make sure you have an active forecast, and at least one forecast run selected (checkbox) for viewing results (Figure 1).
  3. From the Reports tab, click Aggregated Consequence Damages. The Aggregated Consequence Report will open (Figure 3).

  4. In the View By list, select the boundary category you wish to view results by; the default is impact area.
  5. Select the results tab you wish to view. By default the report will display the Economic Damages by impact area tab. The report also provides a Structure Flooded tab, an Agricultural Damages tab, a Critical Infrastructure Damages tab, and a Summary Report tab. The Summary tab (Figure 4) provides information on urban damages, agricultural damages, total damage, acreage flooded, structures flooded, and population impacted.

  6. You can save the report to a text file or print the report. Click Close, the Aggregated Consequence Report will close.
