Abstract: Numerical simulation technology has been playing an important role in groundwater researches. After the development of MT3D, it has been widely used to predict and evaluate the fate and transport of the dissolved contaminants in groundwater. MT3D has four different numerical solvers in it—MOC, HMOC, MMOC and UFDM. In order to research the applicability of these four different numerical methods, a one dimensional numerical groundwater flow model was developed via Processing MODFLOW Pro.7.0.5, 14 cases, combined by different dispersivities, adsorption coefficients and degradation rates, were simulated, and the results were compared with the theoretical results. Suggestions on how to select the numerical solvers for different simulating needs are summarized based on this research.
