EVALUATING POTENTIAL LAND SUBSIDENCE INDUCED BY GROUND WATER WITHDRAWAL FROM THE INDIAN WELLS VALLEY, CA USING INSAR
Interferometric Synthetic Aperture Radar (InSAR) is a proven tool to assess ground surface response to aquifer depletion. InSAR provides a much better spatial coverage than classic surveying techniques. Radar data have been acquired over this area since 1992 and the arid climate of this region is very favorable for InSAR processing. This study attempts to utilize multiple year, stacked Interferometric Synthetic Aperture Radar (InSAR) results to identify portions of the valley that have subsided since 1992 in an effort to better delineate the portions of the local aquifers that are the most heavily stressed by groundwater production.
