The results show that the seepage from the Yongding River without liners can greatly raise the groundwater level. Leakage through liners constructed with geomembranes can effectively control the seepage of water and the spread of solutes in the aquifer. From June 2009 to December 2010, the leakage amount has been only 1.65 × 104 m3, and the unconfined aquifer shows a negative budget of 4.55 × 107 m3. The spreading extent of flow and potential pollutants increases with the amount of leakage from the river. Water management strategies, such as the South‐to‐North Water Diversion Project and Yongding River restoration could help alleviate the water deficit of the Yongding River alluvium f...
