Suitability of the numerical simulation approach for estimation of longitudinal dispersivity in heterogeneous media
非均质渗透介质纵向弥散度数值模拟估算法适宜性探析

A few of numerical solution methods are briefly introduced, including MOC,MMOC,HOMC, and TVD, which are implemented in MT3DMS. Comparative analyses of mass errors and longitudinal dispersivity values obtained using the different methods were conducted. In addition, the impacts of the grid size and source concentration were examined. We present the basic procedure and the suitability analyses for longitudinal dispersivity estimation by numerical simulations.
