Abstract

In this study, the permanent scatterer InSAR (PS-InSAR) technique was utilized to monitor land subsidence in Asadabad city and the adjoining plains located in the west of Iran using Sentinel-1A satellite images in the 2015–2018 period. Based on the results, the Bad Khoreh area exhibited the maximum subsidence rate of about 224 mm/year among the examined areas in the county in the selected period. Also, the rate of land subsidence had increased from the urban areas toward the plains. Moreover, the processing of underground water level data of piezometric wells in the study area indicates that land subsidence in Asadabad city and the adjacent plains has a direct relationship with the overexploitation of groundwater resources during the 2015–2018 period. Furthermore, subsurface geology and land subsidence were analyzed based on information gathered from eleven wells with a total depth of 614 m. The examination of borehole logs and profiles demonstrated that the areas composed of fine clay and sand had undergone severer subsidence than those composed of coarse-grained sediment due to the greater consolidation and compressibility of the grain sediment.
