Flood Monitoring with X-Band and C-Band SAR: A Case Study of the 2021 British Columbia Floods

Floods are among the most common and destructive extreme weather events in the world. Spaceborne synthetic aperture radar (SAR) systems are well-suited for monitoring flood events given their ability to operate in near all-weather and all-time conditions. We present a case study classifying imagery from both the commercial very high resolution (VHR) Capella Space X-band constellation and the public C-band Sentinel-1 mission. We use inferred flood extents from these disparate sources to investigate the progression of unprecedented inundation over Abbotsford, British Columbia in November - December 2021.
