Abstract:

This study specified a polluted riparian zone of Sui River, Huaibei in Anhui Province to research the effect of common surface pollutant sources on groundwater. Based on a field investigation, pumping test and slug test in the polluted riparian zone, a systemic study was carried out in respect of hydrodynamic. Processing Modflow was used to establish the hydrogeology model, we can discriminate the hydraulic connection among the polluted river, the deep aquifer and the shallow aquifer, according to the situation of water exchange among subregions. The results of simulation demonstrated that there was no obvious hydraulic connection between the polluted river and the shallow aquifer, and the hydraulic connection between the deep aquifer and the shallow aquifer was weak.

Key words: riparian zone, surface pollutant source, Processing Modflow, hydraulic connection, hydrodynamic
