Abstract
The rise of "sponge city" construction in China has promoted the development of recharge facilities such as rainwater gardens and rainwater seepage wells, but there is a lack of research on the impact of practical projects on groundwater. Rainwater infiltration has the risk of polluting groundwater, so recharging groundwater in these ways may increase the risk of secondary pollution of groundwater. Visualization technology can reveal the occurrence conditions, dynamic characteristics and movement changes of groundwater, and reveal the hydrogeological conditions in the study area.
