| Abstract: | It was employed Visual Modflow4.1 software to establish the model of groundwater flow and quality based on hydrogeological conditions and groundwater utilization in the east basin of Zhangye,and to determine the contaminant migration and initial concentration through calculating pollutional load.The displacement of contaminant to the capture zone of water source within a certain interval time can be calculated by the quality stimulation model running under the environment predicted by the flow model on the basis of the future water exploitation activities,and it will be used as grading criteria to outline the first class protect zone where the migrating interval time is 100 day,the second class zone with 1 000 migration day,and quasi-protected areas between the boundary of the second zone and recharge area. |
