Physical exposure to flood
The metric for the natural hazard risk used in INFORM is the annual average exposed population (AAEP) or, when hazard maps for different return periods are not available, annual exposed population (AEP). The Source of the data are taken from the GAR 2015 flood hazard maps 25, 50, 100, 500, 1000 years RP. The score of the Flood component is based on the AAEP risk metrics. The GAR 2015 flood hazard map displays probable inundated areas related to a specific return period. Inundated areas are not broken down into different water height levels, so only binary information is provided for each point, which is positive if the location is inundated and negative if not. The hazard zones are derived from all inundated areas for each return period. |
