Investigating the causes of subsidence is important in order to prevent its progression, and decisions should be based on the characteristics of each region. While the drop in groundwater level is an important factor affecting subsidence, there is no direct linear relationship between changes in groundwater level and subsidence due to the complexity of other influencing factors. Therefore, this research aims to investigate the relationship between subsidence and changes in groundwater levels in the Esfarayen region of plain during the period of 2015 to 2021. The study analyzed the time series of radar interferometry and the water level of piezometric wells in the area of Esfarayen. The results show that there is a correlation between the decrease in groundwater level and the increase in subsidence in the studied area. However, due to the complexity of the relationship between subsidence and its contributing factors, further investigation and more comprehensive models are necessary.
