| Abstract: | We demonstrate the effectiveness of long‐term continuous interferometric Synthetic Aperture Radar (InSAR) monitoring for local resource management. Sustainable yield is a key concept in groundwater management to ensure sustainable, low‐impact groundwater extraction. This study proposes to estimate sustainable yield using InSAR, combined with local groundwater production data. We apply this method to the Hollywood Basin in Los Angeles, California, leveraging nearly 30 years of InSAR data (1992–2023) to investigate ground deformation linked to groundwater extraction. High spatial InSAR measurements reveal deforming regions linked to anthropogenic activities previously not well‐characterized by in situ observation networks. By integrating InSAR data with production records, we estimate the sustainable yield for the basin to be 1.44 to 1.67 million cubic meters per year, significantly lower than the current operating safe yield of 3.70 million cubic meters per year. Utilizing Independent Component Analysis, we are able to distinguish hydrological signals originating from the deep and shallow aquifers in the Hollywood Basin. Our findings demonstrate the effectiveness of InSAR for long‐term monitoring of anthropogenic deformation and for supporting urban planning and resource management. Key Points: A 30‐year interferometric Synthetic Aperture Radar (InSAR)‐derived deformation time‐series yields critical insights into anthropogenic impacts uncharacterized by in situ networksInSAR measurements and production records can effectively guide sustainable yield determinations for groundwater productionWe identify aquifer responses from different depths in the Hollywood Basin using Independent Component Analysis [ABSTRACT FROM AUTHOR] |
