Monitoring of Land Subsidence in Qorveh and Chahardoli Plains of Hamadan and Kurdistan Provinces using PS-InSAR Technique

Land subsidence occurs more slowly and gradually in comparison with other natural hazards, such as floods and earthquakes; therefore, it has received much less attention from human communities. However, the subsidence over time causes irreparable damage to the structure of underground aquifers, vita...

description Land subsidence occurs more slowly and gradually in comparison with other natural hazards, such as floods and earthquakes; therefore, it has received much less attention from human communities. However, the subsidence over time causes irreparable damage to the structure of underground aquifers, vital infrastructure such as roads, power lines, and urban structures. In this study, in order to monitor land subsidence in Chahardoli and Qorveh plains located in Hamadan and Kurdistan Provinces, the method of Permanent Scatterer (PS) was used using 59 images of Sentinel satellite in ascending passage and 58 images in descending passage. According to the average displacement of PSs in the region between Hassan Abad Emam and Ahutapeh villages of Asadabad city located in Chahardoli plain of Hamadan Province, displacement in the form of subsidence for Ahutapeh and Hassan Abad Emam villages respectively about -170 and -166 mm was happened in the time period of 2017-2018. Moreover, the research found that the subsidence in the northern part of Chahardoli plain in Hamadan Province is much more than the subsidence in the southern part of Chahardoli plain in Kurdistan Province. In order to find the cause of subsidence, the approach of examining the information of piezometric wells in the region and their changes over time was used. In this regard, it can be concluded that the land subsidence in Qorveh plain and Chahardoli plain of Hamadan and Kurdistan provinces can be attributed to the uncontrolled extraction of groundwater resources.
