Setting Inland Flood Options

During a catastrophe peril analysis, the inland flood peril applies to precipitation events that cause inland flooding due to river overflow, as well as to overflow caused by inadequate drainage systems. Flood zones are based on FEMA and AIR flood zone categories.

Note:

Storm surge is not accounted for in the flood model.

When you import or enter location-surrounding details for exposures, you can specify the custom flood zone to which each exposure belongs. Then, when you configure a catastrophe peril analysis that includes the inland flood peril for Europe, you select any of the following flood zones that you want to include in the analysis:

  • Zone 1

  • Zone 2

  • Zone 3

  • Zone 4

Touchstone also provides a Default option that enables you to include in an analysis exposures that have not been assigned to a specific custom flood zone.

Note:

The Flood Zones options in the Loss Analysis Options: Inland Flood dialog box apply only to flood analyses for Europe. These settings do not apply to models in other regions. Selecting the flood zones has no impact on the results outside Europe. The Source of Flooding options in the Loss Analysis Options: Inland Flood dialog box apply only to flood analyses in the United States and have no effect on other regions.
