Landslide Risk Potential Mapping after wildfires

 

Landslide Risk potential Mapping after wildfires

Wildfires make the landscape more susceptible to landslides when rainstorms pass through an area after wildfires. Post-fire debris flows are particularly hazardous because they can occur with little warning, can exert great impulsive loads on objects in their paths, and can strip vegetation, block drainage ways, damage structures, and endanger human life. Often there is not enough time between a fire and a rainstorm to implement an effective emergency response plan. However, various post-fire debris-flow hazard assessment models have been developed to estimate the probability and volume of debris flows that may occur in response to a storm.

 We can use of ArcGIS Pro to create a landslide risk map after wildfire. Through the use of Raster function chain in ArcGIS Pro we can derive a burn severity map, topographic slope map, and a land-cover index map. With the help of Weighted overly function can integrate the all these map to map the landslide potential risk map after wildfire of an area.
