| Abstract: | 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. |
