Research On The Protection Of The Fountains By Means Of Artificial Recharge Of Groundwater In Jinan City

Now, artificial recharge of groundwater is an effective way to control the declining level of the groundwater and hold back the geologic disasters. Many countries in the world are practicing to use this way to protect groundwater. In some places, the sewage is recharged, and it will be reused after being purified by ground.In this paper, the influence to the level of the groundwater by means of recharge groundwater in Jinan city was analyzed, and the rule of the dynamic movement of the level of groundwater was got. The hydraulic relation between the fountains and their sources was also analyzed. The recharge efficiency and the rule of transformation between surface and groundwater were calculated. At last, the water level of the fountains was forecasted by using a hydro-geological model.The result is rational, there is closely hydraulic contact among the aquifers in Jinan city, also between the water source in the west suburb and the fountains, so it will be in influential to the fountains exploiting the water in the west suburb; The effect on the groundwater is good and the coefficient of recharge is 80.79%; So the water can satisfy the need of the industry, agriculture and the living of citizen in Jinan city and can ensure the fountain at the same time, if the utilization of the surface water and groundwater is reasonable.
