In terms of the main factors which potentially caused land subsidence, the numerical model of land subsidence was established. With three groundwater extraction scenarios, the computer program was compiled to predict the land subsidence in the process of dynamic changes of groundwater level. Maintaining the same condition of groundwater exploitation in 2007 (Scenario 1), from 2007 to 2020, with 2% decreases in groundwater exploitation year by year (Scenario 2), with the water from South-to-North Water Transfer Project replacing groundwater exploitation completely (Scenario 3), the maximum accumulative subsidence in Binhai New Area of Tianjin (TBNA) will be 640, 520, office:smarttags" />
