Regarding the replenishment and drainage relationship between groundwater and river water, when there is a hydraulic connection between the two, based on the flow movement pattern and the water level dynamics of groundwater and river water, It is divided into horizontal flow, three-dimensional flow and disconnection between groundwater and river water. Horizontal flow When the aquifer medium is homogeneous and isotropic and the river completely cuts through the phreatic aquifer and is directly connected to the underlying confined aquifer, the groundwater will approximately flow horizontally. The replenishment and discharge relationship between river water and groundwater depends on the river water level and the piezometric water level of the aquifer. When the river water level is higher than the groundwater level, the river water recharges the groundwater; when the river water level is lower than the groundwater level, the river water drains the groundwater.
