Abstract:

Based on the hydrogeological conceptual model and land subsidence model according to the hydrogeological mechanisms of groundwater system and land subsidence mechanisms in the development zone along the Yangtze River in Jiangsu Province, a three-dimensional numerical model for groundwater withdrawal and land subsidence is established. Aiming at controlling the land subsidence, the optimal exploitation scheme for each aquifer is presented, which provides a scientific foundation for exploiting groundwater reasonably and controlling land subsidence in the area.
