Analysis of Influence to River Water and Underground Water Relating the Riverside Pumping

Based on river treatment and ecological restoration around interrelation between river water and underground water during riverside pumping. One section of BeiYun river which is a comprehensive treatment project channel dominated by silty fine sand as study area was chosen as an example. It has an effect on stimulated river infiltration capacity and also has influence on underground water when riverside pumping studied by means of numerical simulation. The results show that it is applicable to calculate aquifer permeability coefficient by mirror method in the study area, and on another hand the results show that it is different distance 50 m, 100 m and 150 m from riverside that is predicted to research water intake near the riverside and find out that the farther away the water intake well is from the riverside, the weaker the stimulated river infiltration is within the scope of simulation distance. when distance is 150 m, the effect on stimulated river infiltration capacity is very little and the abstracted water will maily derive from local underground water.
