Converting a NEXRAD Rainfall Map into a Flood Inundation Map by ...

and then use it as the field value of the Rater to Polygon operation. The finalraster outcome should be comparable with the previous raster and the duration ofthis alternative is also comparable. The schematic of this second alternativeapproach in ModelBuilder is shown in Figure 4.51.Figure 4.51 Create Flood Inundation Map Model Workflow (Option 2)Therefore, the modeler may try different alternatives for the delineation ofthe floodplain map to make sure the final scheme satisfies calibration, andvalidation criteria.Even though the above discussion about each of the individualcomponents of the Map2Map application is for the case of historical precipitationevents from NEXRAD sources, most of the individual processes can be reused forother use cases due to the modular character of the application.
