摘要
将梯度正则化方法(Gradient-Regulation method)应用于地下水溶质运移数学模型(对流—弥散方程)的源项反演,研究了山东省淄博市张店区沣水南部区域地下水中硫酸盐年入渗强度的数值反演问题.算例结果表明了应用梯度正则化方法解决此类问题的有效性和可行性.
In this paper, Gradient-Regulation method is applied to a source inverse problem of one--dimensional convection dispersion equation. The average magnitude of acid pollutants sources in groundwater in Fengshui in Zibo in Shandong province is solved effectively. The program realization and numerical calculation of the concrete calculating examples can testify the efficiency and feasibility of Gradient-Regulation method to solve such kind Of inverse problems.
