Land subsidence is a natural hazard characterized by gradual movement, resulting in financial losses and, occasionally, loss of life. This research employs interferometric radar techniques to study morphological changes in the Kahrez Plain aquifer. The extent of land subsidence in the Kahrez Plain aquifer is investigated using Sentinel-1 satellite imagery from 2014 to 2023. This aquifer is situated in the western subsidence of Lake Urmia and is predominantly composed of limestone lithology. The geological structure in the area comprises inclined layers and the effects of fault activity. Microscopic examinations of rocks from the region reveal dual fractures, displacement, collision, and simultaneous rotational phenomena, indicating the role of tectonics in shaping the existing structures in the area. According to the interferometric analysis results, no land subsidence has been observed in the Kahrez Plain aquifer during the study period, and the uplift ranges from 0.34 to 1.51 meters. Regional deformation, resulting from changes in landforms such as earthquakes or tectonic activities, could be a significant factor contributing to the notable uplift. [ABSTRACT FROM AUTHOR] |
