| Abstract: |
| 【Objective】 Study the effect of artificial recharge on the spring water level in Jinan city. 【Method】 On the base of systematically analyzing the hydrogeological conditions, the numerical model of groundwater flow in Baotu Spring area was established using GMS10.0. And the effects of artificial recharge in Yufu River, Liyang Lake and Xingji River were evaluated. 【Result】 The results showed that the recharge water in Yufu River recharged the western suburb ground water along the Chaomidian graben from south to north firstly, and then flowed eastward and westward. The maximum influence range of artificial recharge in Yufu River was 614.32 km2 and the maximum raised water level of Baotu Spring and Heihu Spring were 0.06 m and 0.04 m after 177 days, respectively. The recharge water in Liyang Lake reached the Baotu Spring after 77 days, and the maximum influence range was 155.52 km2 and the maximum raised water level of Baotu Spring and Hehu Spring were 0.04 m and 0.03 m, respectively. The maximum influence range of artificial recharge in Xingji River was 198.91 km2 and the maximum raised water level of Baotu Spring and Hehu Spring were 0.02 m and 0.01 m after 329 days, respectively. 【Conclusion】 The artificial recharge in Yufu River, Liyang Lake and Xingji River played a positive role on the spring water level. |
