摘要
在地下水水文模拟过程中GMS模型具有广泛的适用性与科学性,以大凌河流域为例对水文水质状况与污染物迁移趋势采用GMS模型进行模拟研究。采用概化的方法建立流域水文地质数学模型与概念模型,对模型主要参数利用反演迭代法进行校正,对流域污染物迁移趋势与水文水质状况采用MT3DMS、MLDFLOW模块进行预测模拟。研究表明:流域水文水质检测值与模型模拟结果保持较好的一致性,校正后的GMS模型能够较好的反映流域地下水系统的污染物迁移趋势和水文水质状况,模型呈现出较强的科学性与准确性,可为污染源的控制与方案措施的制定提供一定参考。
GMS model has wide applicability and scientificity in groundwater hydrological simulation.Taking Daling River Basin as an example,GMS model is used to simulate the hydrological water quality and pollutant migration trend.The mathematical model and conceptual model of hydrogeology in river basin are established with generalized method.The main parameters of the model are corrected by inversion iteration method.MT3DMS and MLDFLOW modules are used to predict the trend of pollutant migration and hydrological and water quality in river basin.The results show that the valley hydrological and water quality monitoring values are in good agreement with the model simulation results.The corrected GMS model can better reflect the trend of pollutant migration and the hydrological and water quality status of the groundwater system in the valley.The model shows strong scientificity and accuracy,which can provide a certain reference for controlling the pollution sources and formulation of schemes and measures.
