Abstract—The conceptual hydrogeological model of the study distributed widely and exposed in hilly area and river valley.
area is generalized according to the hydrogeological conditions, The weathering of rocks is strong in the area, and the thickness
and then the numerical model of groundwater flow is built by of weathering belt is between 50m and 80m. The fragmentary
MODFLOW-2000. Under current condition of groundwater aquifer under Quaternary pore water has a good recharge
exploitation, the groundwater flow field in the year 2018 of the condition. The depth to groundwater level is between 6m and
study area is forecasted. The result shows the groundwater level 30m, and the yield of single well is between 217 m3/d and 750
will decrease in the river valley of Jixi City, and drainage of local m3/d. The annual amplitude of groundwater level is between
aquifer occurs in the lower reach of Muling River Valley. The and .
numerical model provides a significant scientific basis for
