The USGS is using a GIS to model the spatial distribution of post-fire debris flow potential. Debris flow models are based on terrain and soils information, rainfall conditions, and burn–severity data representing recently burned areas.
The USFS is using a GIS to model burn–severity in recently burned areas.
