Overexploitation of groundwater is the major factor responsible for ground subsidence in many areas. The development of the SAR Interferometry (InSAR) technique provides a powerful tool for revealing the detailed evolution of subsidence with the advantages of large coverage, dense spatial sampling and high temporal frequency. In this study, the authors present an example of complex deformation procedure monitoring by time series analysis of coherent point target with small baseline subsets. Taking Dezhou as the study area, the authors analyzed the subsidence evolution during the period from January 2004 to October 2010 by using the ENVISAT ASAR data. The causes of the seasonal subsidence and rebound were investigated by analyzing the groundwater pumping as well as leveling surveying and weather data. It can be concluded that the continuous overexploitation of the groundwater and the yearly rainfall changes are the major factors responsible for seasonal subsidence and rebound, which result in the close temporal relationship between subsidence and water level changes.
