在许多区域水资源水环境问题中 ,地下水流和水质的模拟往往采用数值方法 ,需给出各个节点的初始水位值以反映流场的初始状态 .本文阐述了以容易获取的节点地表高程信息 ,作为协同区域化变量 ,用协同 泛克立格法进行地下水位估值的原理 ,并以河南省焦作市修武段地下水数值模拟分析区为例 ,说明了利用该方法时的实验变差函数获取方法 .通过与未加入协同区域化变量地表高程的泛克立格法进行比较 ,证明本文建议的方法对松散多孔介质区域地下水位估值有更好的效果
In many regional water resources and water environment problems, groundwater flow and water quality are often simulated by numerical methods, and the initial water level of each node needs to be given to reflect the initial state of the flow field.This paper presents an easy-to-obtain node surface elevation information, As a synergistic regularization variable, the principle of synergistic Universal Kriging for groundwater level estimation is introduced. Taking the groundwater numerical simulation analysis area of Xiuwu section in Jiaozuo City of Henan Province as an example, the experimental variogram acquisition The results show that the proposed method has a better effect on the estimation of groundwater level in loose porous media area by comparison with the results of universal Kriging without adding regional surface variables
