    Numerical Simulation,Prediction and Analysis of Pollutants Transport Based on VM-MT3D by WANG Chengwen

    Published 2020-01-01
    “…The research on numerical simulation of groundwater solute transport is practical significance for the protection and utilization of groundwater resources.This paper simulates and predicts the groundwater solute (that is,NH<sub>3</sub>-N) leakage concentration in the study area,and analyzes the pollution concentration process of leakage treatment station and its downstream factory area.It is found that the farthest influence distance of NH<sub>3</sub>-N pollution plume is 496.2 m,and the range of pollution plume is 36 800 m<sup>2</sup>.In addition,it takes about 7.4 years and 14.8 years for the leakage treatment station and its downstream factory area to reach groundwater class III standard limit,respectively.Finally,after verifying and identifying the groundwater solute transport model,it is found that the difference between the simulating water level by model and the actual water level is 0 m to 1.2 m.Therefore,with small water level error,the accuracy requirements of simulation and prediction are satisfied.…”
