Analytical method for calculating the leakage between river and groundwater

With the aim of exploring the dynamic process of the relationship between river water and groundwater, a mathematical model for the unstable seepage process of groundwater under sudden changes in river water level is established. Taking the No. 5 rubber dam reservoir area of the Bahe River as an example, the variation of groundwater level around the reservoir area after the rubber dam storage is analyzed, and the relationship between the amount of groundwater replenished by the river and time is simulated, Calculate the changes in groundwater level around the Bahe River and the amount of seepage in the Bahe River after the rubber dam is filled with water.
