HEC-FIA may be used in HEC-RTS 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).
    Figure 2 Individual Structure Damage Report
  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). 
    Figure 3 Aggregated Consequence Report
  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. 


Detailed Life Loss Report

The Detailed Life Loss Report is dependent on the HEC-FIA model alterative being setup to compute life loss. This report provides information about how HEC-FIA calculated life loss for the watershed.

To view the Detailed Life Loss Report:

  1. From the Modeling module, to view the Detailed Life Loss Report, make sure you have an active forecast and at least one forecast run selected (checkbox) for viewing results. From the Forecast Runs Detail section, select an HEC-FIA model alternative (Real-Time), from the Forecast tabs, click Reports.
  2. Click Life Loss, the Detailed Life Loss Report (Figure 7) displays by Total. The Detailed Life Loss Report provides information about how HEC-FIA calculated life loss for the watershed. For further details on this HEC-FIA report, refer to the HEC-FIA User's Manual.
  3. From the View By list (Figure 7) you can also view the Detailed Life Loss Report by Emergency Planning Zone, Damage Category, and Occupancy Type.
  4. To close the Detailed Life Loss Report, click Close, and the Detailed Life Loss Report dialog will close (Figure 7).

ECAM Reports

The ECAM Report is dependent on the HEC-FIA model alterative being setup to compute life loss and ECAM. For the example HEC-RTS watershed being used in this User's Manual, the HEC-FIA model alternative (Real-Time) is not setup for an ECAM compute, therefore no results.

To view ECAM reports:

  1. From the Modeling module, to view the ECAM reports, make sure you have an active forecast and at least one forecast run selected (checkbox) for viewing results. From the Forecast Runs Detail section, select an HEC-FIA model alternative (Real-Time), from the Forecast tabs, click Reports.
  2. There are two ECAM reports (tabs) - Output and Employment. When the Output tab is selected, the ECAM Indirect Economics Output Report displays. The ECAM Indirect Economics Output Report provides information about the output of the economy, by sector (e.g., forestry, food processing, general manufacturing, etc.) for a selected county (County list). When the Employment tab is selected, the ECAM Indirect Economics Employment Report displays. The ECAM Indirect Economics Employment Report provides information representing the changes in labor employed by sector (e.g., forestry, food processing, general manufacturing, etc.) for a selected county (County list).
  3. To close either ECAM report, click Close, and the ECAM report will close. For further details on this HEC-FIA report, refer to the HEC-FIA User's Manual.

Impact Response By Rule Report

The Impact Response By Rule Report is dependent on the HEC-FIA model alterative having an impact response element defined. This report displays the hydrograph at the location of the rule, and the threshold elevation relative to the hydrograph. The Impact Response By Rule Report displays each rule independently.

To view the Impact Response by Rule Report (Figure 8):

Figure 8 HEC-FIA - Impact Response by Rule Report

  1. From the Modeling module, to view the Impact Response by Rule Report, make sure you have an active forecast and at least one forecast run selected (checkbox) for viewing results. From the Forecast Runs Detail section, select an HEC-FIA model alternative (Real-Time), from the Forecast tabs, click Reports.
  2. Click Impact Response By Rule, a dialog will open (Figure 8). From the list at the top of the dialog (Figure 8), select which rule you would like to review (e.g., Russian River near Hopland Moderate Flood Stage (Gage 24.00)). A plot of the hydrograph at the location of the rule is displayed (Figure 8). In addition, both the Impact and Response boxes provide details. For further details on this HEC-FIA report, refer to the HEC-FIA User's Manual.
  3. To close the Impact Response By Rule Report, click OK, and the dialog will close (Figure 8).

Critical Infrastructure Report

The Critical Infrastructure Report is dependent on the HEC-FIA model alterative having a critical infrastructure inventory defined. The report only includes critical infrastructure elements which were inundated.

To view the Critical Infrastructure Report:

  1. From the Modeling module, to view the Critical Infrastructure Report, make sure you have an active forecast and at least one forecast run selected (checkbox) for viewing results. From the Forecast Runs Detail section, select an HEC-FIA model alternative (Real-Time), from the Forecast tabs, click Reports.
  2. Click Critical Infrastructure, the Critical Infrastructure Report (Figure 9) displays. For each critical infrastructure, the Critical Infrastructure Report provides information about elevations at ground, water surface, depth, arrival, and duration. For further details on this HEC-FIA report, refer to the HEC-FIA User's Manual.

  3. To close the Critical Infrastructure Report, click Close, and the Critical Infrastructure Report will close (Figure 9).

Flood Damage Reduction Reports

The flood damage reduction reports are dependent on the HEC-FIA model alterative being setup with the necessary hydraulic data and holdout inundation configuration. For the example HEC-RTS watershed being used in this User's Manual, the HEC-FIA model alternative (Real-Time) is not setup properly for generating flood damage reduction reports.

To view flood damage reduction reports:

  1. From the Modeling module, to view the flood damage reduction reports, make sure you have an active forecast and at least one forecast run selected (checkbox) for viewing results. From the Forecast Runs Detail section, select an HEC-FIA model alternative (Real-Time), from the Forecast tabs, click Reports.
