Description
Monitoring Surface Water with SAR for Water Resource Management
Part 1: Flood Mapping with NISAR
This session begins with the fundamental principles of how SAR detects inundation—including the distinct radar signatures associated with open water and inundated vegetation—and discusses the advantages of radar observations for monitoring floods regardless of cloud cover or daylight conditions. The session then highlights the unique capabilities of NISAR for flood mapping, including its global coverage, frequent revisit schedule, and L-band sensitivity to vegetation and surface water. Participants will learn which NISAR data products are most appropriate for flood mapping applications and the considerations for selecting and interpreting these products.
The session concludes with a demonstration in QGIS, where participants will learn how to visualize NISAR data and generate a flood map, providing a practical workflow that can be adapted for flood monitoring and disaster response applications.
