On the basis of Darcy-Gersevanov generalized flow relation between aquifer solid and interstitial water,we have derived the analytical expressions of horizontal aquifer movement and strains induced by fixed-drop withdrawal of ground water from a single well in a Theis-Theim confined system.The numerical calculation demonstrate that,with ground water pumping,the aquifer would radically move inward,and along with pumping time increasing,the velocity of aquifer movement would exponentially decay and the corres...
