To apply FIAT in a Delft-FEWS workflow, you will need an inundation mapstack (e.g. satellite image or flood inundation model like Delft-FM or 3Di-subgrid) to hand over to FIAT. When providing a max-depth map to FIAT it can calculate the (financial) damage per category on the map or as a total value for the entire area . This max-depth map
The default setup is based on the maximum depth over the entire time horizon, that needs to be prepared in FEWS as a mapstack series with one timestep (e.g. using the statisticalSummary transformation). When you also provide a flood wave (mapstack series with multiple timestep) to FIAT, it can compute the human impact (mortality and casualties) by internal conversion of the wave into (vertical) rise rate and an arrival time map.
As of October 2019, the FIAT-adapter can also accommodate the computation of impact over time by providing a mapstack which holds the maximum depth that has occured from the beginning of the simulation up to the current timestep. FIAT-adapter
The FIAT-adapter (fews_wrapper.py) is wrapped around the FIAT computational core and available in the FIAT distribution. To accommodate portability without python installation troubles, a self-contained executable (FIAT.exe) is available on request with Edwin Bos at Deltares.
