Effect of Reclamation on the Groundwater-Lake Water Interaction in Chen Lake

Abstract

Lake reclamation cut off the direct seepage from the lake to groundwater in reclaimed farmland, the aquifer showed a connection with lake water by horizontal groundwater flow. The chemical analysis demonstrated that after reclamation, groundwater hydrodynamic conditions are gradually weakening. The lake-groundwater interaction interface is gradually varied and moves into the lake during this period. This change is easily ignored because the modification may take years to be observed. However, the lake ecology may be threatened seriously during this process. Lake reclamation project exerts anthropogenic pressures on the groundwater environment and lake ecosystem function, would affect the natural resilience of the lake systems and increases their vulnerability.
