Infrastructure Tunnel Impact Modeling on Groundwater with MODFLOW6 and mf6Voronoi Studio – Tutorial

This tutorial demonstrates how to model the hydrogeological impact of an infrastructure tunnel on a local groundwater flow system using MODFLOW 6 and mf6Voronoi Studio. The exercise simulates a four-year tunnel excavation process through a mountainous terrain bounded by two creeks, evaluating how gradual underground construction affects local water table levels and surrounding flow dynamics. The model utilizes an unstructured Voronoi mesh generated in mf6Voronoi Studio to achieve precise local grid refinement and seamless geometry representation along the tunnel alignment and stream network. Additionally, the model incorporates local geology, dynamic drain boundaries, and transient stress periods to capture the groundwater system's temporal response to underground construction.
