Abstract
The Yellow River flood plain in northern of China, affected by the low precipitation and the large amount of well irrigation, is facing the ecological problems of serious groundwater overdraft and expansion of drawdown cone area. Taking Linqing city of Shandong Province as an experimental area, the technical scheme and parameters of Open channel-Underground perforated pipe-Shaft groundwater recharge system were designed by combining theoretical calculation and field test, and the effect of recharge was observed and analyzed. The results show that this project has increased groundwater amount of 52310.82m3 by water diversion for 7 days compaired with existing canal system, accounting for 60.7% of the total groundwater recharge. This recharge technology can effectively increase the amount of groundwater replenishment and raise the groundwater table as well as scope of groundwater recharge. It has the advantages of no energy consumption, no land occupation, rechargeability, and drainage. Thus, it is of great significance to the recovery of groundwater drawdown cone area and the comprehensive treatment of drought and waterlogging.
