Numerical Simulations And Risk Control Of Groundwater In The Middle Route Of South To North Water Transfer Project In Jiaozuo

Since the level of the groundwater is higher than the level of main canal bottom of the Middle Route of the South to North Water Transfer Project in Jiaozuo, the polluted groundwater can flow into the canal throw the one-way check valve drainage system. Based on the numerical simulation technology of Groundwater Model System, the groundwater flow model and solute transport model of the study area were established and groundwater pollution risk of four main pollutants was then investigated. And it was also investigated that the changing characteristics of sensitivity of each parameter. Finally, the thesis offers three preventive measures for water of main canal and simulates their effects. This study can provide technical support for water quality safety of the Middle Route of the South to North Water Transfer Project.
