Simulation Analysis of the potential exploitation of groundwater resources based on water projects in Luoyang

摘要

According to the groundwater level changes after the construction of Luohe River water projects in Luoyang, numerical simulation method is used to analysis the exploitation potential of groundwater resources of Luoyang Basin. The results show that the construction of Luohe River water projects strengthen the groundwater recharge from Luohe River, an increase of about 0,8×10~8 m~3/a. The groundwater recharge from Luohe River and Yihe River currently reach 2.78×10~8m~3/a in Luoyang. After the construction of water projects, water extraction volume is increasing at 6×10~4 m~3/d in Luonan water source, the center of the depression cone's water level dropped as deep as 2m; the exploitation amount is increasing at 6 ×10~4 m~3/d in Lilou water source, the center of the depression cone's water level dropped as deep as about 2.2m.
