Abstract

Cangzhou-Hengshui-Nangong subsidence, located in the southeast of North China Plain, has become the largest subsidence bowl with the maximum rates of subsidence and influenced regions in North China Plain. We employ PSInSAR and SBAS algorithms to retrieve deformation time series of Cangzhou-Hengshui-Nangong subsidence area, in order to research its spatial-temporal distribution characteristic of subsidence. Meanwhile, we discuss the correlation between groundwater depth, groundwater funnel areas and land subsidence and the deep-confined groundwater overexploitation bring about large-scale subsidence.
