Contaminant plume modeling of a mining waste rock dump with MODFLOW 6 and mf6Voronoi - Tutorial

August 14, 2025/ Saul Montoya

This tutorial shows an applied case that covers the discretization of a model using Voronoi grids, taking into consideration the water network, the predictive flow area, and the model boundaries. Based on this mesh, a flow and transport model under steady-state conditions is constructed to simulate the contaminant plume over a period of 50 years, evaluated every 5 years. The model includes piezometers and the development of concentrations over time is evaluated using the Pandas library with Matplotlib. Finally, the entire model geometry, boundary conditions, hydraulic loads, and concentrations are visualized in 3D with Paraview.
