摘要
Visual modflow是一个可以对三维地下水水流和溶质运移进行数值模拟评价的标准可视化专业软件。建立了砂箱物理实验模型来研究柴油在含水砂槽中的迁移特征。通过模型检验,各个监测时期观测值和预测值相关系数r值在0.564～0.669之间,证明这种建模方法是合理的和有效的。利用校正的模型对实验室含水砂槽中柴油运移特征进行模拟,发现所建模型可以较为准确地反映出含水砂槽中柴油污染物的分布特征,拟合、验证和预测结果显示该模型可作为地下水管理的有效工具,这为深入研究柴油污染地下水提供理论依据。
Visual modflow is a commonly used visualization professional software for the simulation of three-dimensional groundwater flow and solute transport.We established the aquifer sandy trough physics experiment model to study migration characteristics of diesel in it.Through the model text,the observation and forecast correlation coefficient of diesel pollution is 0.564～0.669.The results show that this method of modeling is rational and effective.The transport of diesel in an aquifer model was simulated using this calibrated model in this study,and it was found that the numerical model can well reflect the characteristics of diesel transport in groundwater.The results of fitting,verification and prediction show that the models can serve as an effective tool for groundwater management and it can provide a theoretical basis for further research on diesel pollution of groundwater.
