一、模型的校正为了解在初步查明研究区水文地质条件基础上所建立的该区地下水水质模型及其计算程序是否正确与可靠,就必须对程序进行检验和对模型进行校正。本次试验研究对程序是利用一维弥散解析法检验的,而模型校正则是把实际资料代入所建立的模型中试算,考察研究区模型水量、水质动态变化的再现状况。一般要取得研究区2—3个水文年度的地下水水位及某种污染质浓度的统测值,选其一组作为初始条件,确定相应边界;再根据测定的有关水文地
I. MODEL CORRECTION To understand whether the groundwater quality model and its calculation program established on the basis of preliminary identification of the hydrogeological conditions in the study area are correct and reliable, the program must be verified and the model calibrated. The experimental study of the program is the use of one-dimensional dispersion analytic test, and model calibration is to substitute the actual data into the model to try to study the model of the study area, the water quality of the dynamic changes in the state of reproduction. Generally, it is necessary to obtain the measured values of the groundwater level and the concentration of certain pollutants in the study area for 2-3 hydrological years, and select one of them as the initial condition to determine the corresponding boundary. Based on the measured hydrological sites
