We wanted to present seawater intrusion modeling in its more primitive form, on a simple aquifer conceptualization and aquifer geometry where the user can focus on the code implementation with MODFLOW6 - Buy package, Flopy and mf6Voronoi. We have also developed a precoded template for seawater intrusion that allows users to reduce time.
Read MoreNext challenges on groundwater modeling facing scenarios of climate change and sustainable groundwater management require the implementation of fully coupled geological models into groundwater flow models. Even though we have dealt with this topic, we still have a lot to do in providing applied cases / tutorials for the hydrogeological unit conceptualization based on geological information with open source codes such as MODFLOW.

Read MoreMining hydrogeology is one of the most challenging faces of hydrogeology since its evaluations are key components for the mine operation and where groundwater related decisions are needed on a short timeframe. We have developed a series of tutorials that will introduce general groundwater modelers to the specific tasks of mine hydrogeology. This tutorial selection starts from regional modeling and goes into inflow and contaminant transport with different levels of complexity.
Read MoreApplied example of the simulation of groundwater inflow to a open pit considering faults of 1 meter thickness. The model has 6 stress period, one steady state and 5 transient stress periods representing the pit development over 4 years of a total mine life of 20 years. The tutorial shows the complete process beginning from mesh creation, model construction, water budget analysis and 3d representation.
Read MoreInfiltration galleries are a low cost and low maintenance option for domestic water supply. The amount of inflow water and the interaction with the water bodies are main concerns on the evaluation and design of infiltration galleries. We have done an applied case of inflow simulation to infiltration galleries with MODFLOW6 based on Voronoi meshes. The example covers all steps from mesh creation, steady state model construction, simulation of infiltration galleries and the inflow calculation per gallery group. Finally a 3D representation of the model geometry, boundary conditions and head distribution is performed on Paraview.

We have optimized the way we can represent the surface of future (or current) water reservoirs on a fully geospatial raster. This tutorial shows the complete process to create a geospatial raster (TIF file) based on the contours from the dam and the reservoir extension.

We have already covered the simulation of pit inflows with Voronoi meshes and now we are going to model the seepage from a tailings storage facility. The applied case covers all steps from mesh construction, flow model and transport model. Results are plotted on 2d and exported to 3d in Vtk format.
Read MoreSometimes regional models are required as an input for local models of flow and transport. This is an applied case of the groundwater modeling on the regional scale in the state of Guerrero, Mexico that will be the input for future local models of pit dewatering, and contaminant transport from the tailings dam and waste dump. The groundwater model is built with MODFLOW6 and mf6Voronoi on a series of Jupyter Notebooks and results are plotted with Paraview.

This tutorial shows an applied case of determination of a depression cone from an open pit model built with MODFLOW6, Flopy and mf6Voronoi. The model has faults and the tutorial covers all steps from model import, data processing and export of geospatial data from the depression cone.
Read MoreThe interaction of faults with the groundwater flow regimen on an open pit is a challenge on the conceptualization and simulation. Having smaller cells on the faults alignment with higher K can represent the general behaviour of faults and this is possible to simulate with MODFLOW 6 Voronoi models with Flopy and mf6Voronoi package. We have created a tutorial that implements faults on the area of influence from an open pit and defines zone budgets for the pit and drainage network.
Read MoreThis tutorial show the complete workflow to determine flow directions from a MODFLOW model done with Model Muse with the Mf6Voronoi utility FlowVectorGenerator that represent flow direction vectors in a Matplotlib figure. The function works not only with normal Modflow6 Dis models like the generated by Model Muse but also with Voronoi based Modflow6 Disv models. There is a capability to insert background images and other functionalities, however the styling options are closed in order to preserve the artistic style of the plot.
Read MoreModel Muse is an awesome tool for groundwater model construction and output visualization, however its graphical capabilities are quite limited. Since we are always on the search of bringing groundwater model ‘close’ to the stakeholder, normal audience and coming generations, there is a special interest in providing complementary tools for the normal workflow with Model Muse and Modflow6 that allows the normal user to create awesome 3D objects representing:

The Python package mf6Voronoi offers a structured workflow to generate 3D spatial files on VTK format for the representation of the model parameters, water table, head distribution and others that can be plotted on Paraview.
