NASA ARSET: Measuring Surface Subsidence due to Groundwater Extraction with InSAR, Part 2/3
SAR for Detecting and Monitoring Floods, Sea Ice, and Subsidence from Groundwater Extraction
Part 2: Measuring Surface Subsidence due to Groundwater Extraction with InSAR
Trainers: Erika Podest (JPL)
Guest Speakers: Eric Fielding (JPL)
Groundwater-related subsidence of land results from groundwater extraction and extreme subsidence from rapid unsustainable extraction often results in major damage to local infrastructure or urban areas where buildings interact with the settlement, and cause cracking, tilting, and other major damage. Monitoring land subsidence through time on the order of centimeters with the use of interferometric synthetic aperture radar (InSAR) can help inform authorities on the surface effects of extraction of groundwater and its potential impact on infrastructure, and help to distinguish unsustainable groundwater extraction from recoverable variations of groundwater levels. This session will provide a summary of InSAR and will focus on how to work with pre-processed interferograms with Jupyter Notebooks and Sentinel-1 data to measure land surface subsidence due to groundwater extraction.
