Multi-temporal InSAR, in combination with ascending and descending Sentinel-1A data, was applied to obtain two-dimensional surface deformation of the Alto Guadalentín basin from January 2020 to December 2022. The time series deformation, which was refined by independent component analysis (ICA), was then integrated with groundwater level data to estimate the aquifer parameters in the study area. The results showed that the main deformation center of the Alto Guadalentín basin was close to Lorca city in the north and the deformation mainly occurred in the vertical direction with the maximum deformation rate of -65 mm/a. Moreover, the Alto Guadalentín basin represented two different spatiotemporal deformation characteristics: long-term linear deformation and seasonal deformation. The skeleton storage coefficient of the aquifer in the study area ranged between 0.66×10-2 and 2.93×10-2, the average annual groundwater storage loss is -3.8×107m3, which was consistent with the previous researches. The research results could provide reference data and information support for groundwater resource management and land subsidence control in the region.
