DESCRIPTION:As climate change progresses\, we are experiencing an increase 
 in the frequency and severity of extreme weather events in many parts of t
 he world. Climate models predict the frequency and severity of these weath
 er events to continue to increase in the future as surface air temperature
 s rise.\n \nIn 2021\, the Canadian province of British Columbia (BC) exper
 ienced one of the most severe fire seasons on record which destroyed commu
 nities and ecosystems across the province. In the same year\, an “atmosp
 heric river” precipitation event led to widespread flooding causing seve
 re damage to roads and communities across BC. There is a correlation betwe
 en severe wildfires and increased runoff following precipitation events in
  some regions.\n \nThere is a need for better prediction\, monitoring\, an
 d management of fire and flood events to mitigate the damages caused by po
 st-wildfire flooding. Remote sensing data and analysis techniques play a k
 ey role in monitoring climate-related natural disasters and helping unders
 tand and mitigate risks to communities\, ecosystems\, and infrastructure i
 n areas that may be exposed to flooding. Free remote sensing datasets alon
 g with free and open source software can greatly reduce the costs and incr
 ease availability of this monitoring capability\, increasing stakeholder a
 ccess to geospatial intelligence.\n\nThis talk presents a tool developed a
 t Sparkgeo for automated mapping of burn severity and extent within waters
 heds of interest. The tool uses multi-source public remote sensing data in
  a cloud-based workflow\, taking advantage of recent open source initiativ
 es including the SpatioTemporal Asset Catalog (STAC). The tool can help as
 sess flood risk from significant rainfall events and may offer essential f
 lood mitigation and risk management knowledge. We present the tool’s dep
 loyment to map 2021 wildfires in several British Columbia watersheds.
