Groundwater Migration Modeling and Parameter Sensitivity Analysis on Contaminated Site

Abstract:

Contamination control and remediation of groundwater is one of the hotness points in environmental protection field. Groundwater contamination numerical simulation is widely used for groundwater contamination transportation. In this paper, we constructed an indoor sandbox to conduct hydraulic control experiment and tracer experiment. We also set up groundwater flow model and solute transport model by computer and chose the model's key parameters for sensitivity analysis. The results indicated that the sensitivity of hydraulic conductivity was highest, which was the key parameter in the groundwater flow model. The sensitivity analysis of solute transport model parameters showed that sensitivity from large to small was: longitudinal dispersion, porosity and hydraulic conductivity. This study can obtain the main parameters in groundwater simulation model and is helpful for the construction of groundwater contamination migration model.
