  • Abstract Fault can function as high-permeability pathways that enhance groundwater flow or as low-permeability barriers that impede groundwater flow and as a consequence may exert a strong influnce on hydroulic head distributions in faulted aquifers. Therefore, it is important to hydrogeologically characterize such fault in many practices. To provide the hydrogeological characterization, conduction of a pumping test in the neighborhood of fault zone is proposed to determine the fault zone transmissivity by previous researchers based on the analysis of drawdown behavior using a simplified analytical solution. The simplified analytical solution assumed the fault zone width is neglected and the recharge rate from the fault to the aquifer is assumed to be proportional to the head difference. In this study, a three-dimensional MODFLOW is used for the simulation of the drawdown evolution during a pumpin test behavior in an aquifer-fault-aquifer system. The drawdown evolutions obtained from the MODFLOW are compared to those from the analytical solution to test the validity of simplification. Results show that the simplified analytical solution may overestimates or underestimate the
    fault zone transmissivity.
