ARSET - SAR for Detecting and Monitoring Floods, Sea Ice, and Subsidence from Groundwater Extraction

Organizer(s) National Aeronautics and Space Administration



October 24, October 31, and November 1, 2023


11:00-13:00 EDT (UTC-4)


This training is a follow-on to the SAR training held in October 2022, which covered detection and monitoring of oil spills, landslides, and floods. This training will expand on the theory and applications of SAR data to detect and monitor floods through the use of SAR time-series in order to more closely monitor the increase/recession of flood waters. This training will also cover two new application areas: the use of InSAR to measure subsidence due to groundwater extraction, and the use of SAR to detect and monitor sea ice. These application areas are important for environmental managers from local, regional, and federal governments concerned with 1.) the impact of groundwater extraction on infrastructure as well as diminishing hydrological resources; 2.) the risk of sea ice on ships and shipping routes as well as the impact of diminishing sea ice on coastal erosion - especially as related to indigenous communities in Alaska and Canada; and 3.) the impact of floods and how monitoring their extent and increase/decrease can help with disaster response activities. This training will address these applications through the use of open-source tools and SAR data to inform on disaster awareness and response and how to best allocate resources to mitigate their impacts.

This training is also available in Spanish.


By the end of this training attendees will be able to:

  1. Generate subsidence maps due to groundwater extraction to inform risk and resource management
  2. Detect and monitor sea ice to identify potential risks to shipping and coastal erosion
  3. Detect and monitor floods in order to more closely monitor increase/recession of flood waters and better inform disaster response and management


Disaster management agencies, including domestic and international government agencies, aid organizations, indigenous communities, students, and academics.
