This dataset represents projected inundation depths for two future extreme rainfall scenarios across Jackson County of Florida. The scenarios were modeled using the Inundate! tool, focusing on both flow-based (drainflow) and ponding (fluvial) flooding. These GIS raster surfaces - Drainflow and Ponding show the depth of rainfall-driven inundation in inches under two future time horizons: the year 2040 (for near-term) and 2070 (for far-term).
Drainflow type of inundation represents projected fluvial flooding caused by rainfall and overland flow. Ponding type of inundation represents localized flooding (aka “blue-spot” or fluvial flooding) due to rainfall accumulation in low-lying areas.
