FAN, FEMA's Alluvial Fan Flooding software, is used to define special flood hazard information in areas subject to alluvial fan flooding. The model does not define the extent of the special flood hazard area (SFHA), rather, develops output information that can, in conjunction with soil, topographic, and geomorphic information, be used to divide the SFHA into zones of similar depth and velocity.

The minimum input required is the flood-frequency relation at the apex. Options allow for consideration of multiple flow paths with or without avulsions during flood events.
