HEC-FIA may be used in CWMS to predict the consequences for a specific event based on output developed with HEC-MetVue, HEC-HMS, HEC-ResSim, and HEC-RAS. This section briefly describes the HEC-FIA reports accessible from the CAVI. For more detail about the reports, please see the HEC-FIA Users Manual. 

HEC-FIA is also used within CWMS to calculate flood damages reduced by using a Holdout Alternative in HEC-FIA. More information on calculating flood damages reduced is available through the Guide to Computing Flood Damages Reduced using CWMS.

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, and you can cycle through the various locations using the dropdown list or the forward/reverse arrows at the top of the dialog.

HEC-FIA - Impact Response by Rule Report

To view the Impact Response by Rule Report:

  1. From the Modeling module, make sure you have an active forecast and one forecast run selected (checkbox) for viewing results. Select an HEC-FIA model alternative and click on the Reports tab.
  2. Click Impact Response By Rule, a dialog will open. From the list at the top of the dialog, select the desired rule (for example Russian River near Hopland Moderate Flood Stage (Gage 24.00)). A plot of the hydrograph at the location of the rule is displayed. In addition, both the Impact and Response boxes provide pre-defined information about the rule. For further details on this HEC-FIA report, refer to the HEC-FIA User's Manual.
  3. Click OK, and the dialog will close.

Flood Damage Reduction Reports

The flood damage reduction reports are dependent on the HEC-FIA model alterative being set up with the necessary hydraulic data and holdout inundation configuration. More information on calculating flood damages reduced within CWMS is available through the Guide to Computing Flood Damages Reduced using CWMS.

To view flood damage reduction reports:

  1. From the Modeling module, make sure you have an active forecast run selected (checkbox) for viewing results. Select an HEC-FIA model alternative, and click on the Reports tab.
  2. Click Flood Damage Reduction Aggregated Report. The Flood Damage Reduction Aggregated Report by default displays the computed impacts by the holdout distribution area and by reservoirs for the structure damage reduction allocation.

  3. Click Flood Damage Reduction Project Report. The Flood Damage Reduction Project Report by default displays the computed impacts by project and by reservoirs for the structure damage reduction allocation.

  4. To close either report, click Close.

Critical Infrastructure Report

The Critical Infrastructure Report is dependent on the HEC-FIA model 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, make sure you have an active forecast and at least one forecast run selected (checkbox) for viewing results. Select an HEC-FIA model alternative and click on the Reports tab.
  2. Click Critical Infrastructure, and the report will open.
    Critical Infrastructure Report
  3. For each critical infrastructure point, the Critical Infrastructure Report provides information about ground elevations, water surface elevations, depth of water, arrival time, and duration. For further details on this HEC-FIA report, refer to the HEC-FIA User's Manual.
  4. Click Close, and the Critical Infrastructure Report will close.

Individual Structure Damage Report

The Individual Structure Damage 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. 

To view the Individual Structure Damage Report: 

  1. From the Modeling module, make sure you have an active forecast and at least one forecast run selected (checkbox) for viewing results. Select an HEC-FIA model alternative and click on the Reports tab.

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

Aggregated Consequence Report

The Aggregated Consequence Report allows the user to aggregate results by any boundary. The default is to aggregate by the Emergency Planning Zones defined within HEC-FIA. 

To view the Aggregated Consequence Report: 

  1. From the Modeling module, make sure you have an active forecast and at least one forecast run selected (checkbox) for viewing results. Select an HEC-FIA model alternative and click on the Reports tab.
  2. Click Aggregated Consequence Damages, and the report will open.
    Aggregated Consequence Report
  3. In the View By list, select the boundary category you wish to view results by; the default is Emergency Planning Zones.
  4. Select the results tab you wish to view. By default the report will display the Economic tab. The report also provides a Structures tab, an Agriculture tab, a Life Loss tab, and a Summary tab. The Summary tab provides information on urban damages, agricultural damages, total damage, acreage flooded, structures flooded, and population impacted.

  5. You can save the report to a text file or print the report. Click Close, and the report will close. 

Detailed Life Loss Report

The Detailed Life Loss Report is dependent on the HEC-FIA model alterative being configured to compute life loss. This report provides information about how HEC-FIA calculates life loss for the watershed. For further details on this HEC-FIA report, refer to the HEC-FIA User's Manual.

To view the Detailed Life Loss Report:

  1. From the Modeling module, make sure you have an active forecast and at least one forecast run selected (checkbox) for viewing results. Select an HEC-FIA model alternative and click on the Reports tab.
  2. Click Life Loss, and the report will open.
    Detailed Life Loss Report
  3. By default, the Detailed Life Loss Report displays by Total. 
  4. From the View By list you can also view by Emergency Planning Zone, Damage Category, and Occupancy Type.
  5. Click Close, and the dialog will close.

ECAM Reports

The ECAM Report is dependent on the HEC-FIA model alterative being setup to compute life loss and the Economic Consequences Assessment Model (ECAM).

To view ECAM reports:

  1. From the Modeling module, make sure you have an active forecast and at least one forecast run selected (checkbox) for viewing results. Select an HEC-FIA model alternative and click on the Reports tab.
  2. Select ECAM, and the report will open.
  3. 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).
  4. Click Close, and the ECAM report will close. For further details on this report, refer to the HEC-FIA User's Manual.
