River Aquifer Groundwater Flow Model with mf6Voronoi Studio and Model Muse - Tutorial

This tutorial demonstrates how to build and simulate a groundwater model focused on river-aquifer interactions using open-source software. The workflow begins in mf6Voronoi Studio, where a Voronoi grid mesh is generated to capture complex spatial geometries efficiently. The mesh is then imported into ModelMuse, where key aquifer properties and essential boundary conditions—including general head, river, well, recharge, and evapotranspiration—are configured. After running the model, the simulated results are evaluated through an analysis of the water balance and head distribution.

Benchmarking mf6Voronoi v0.0.38: Parallel Performance, Scaling Limits, and Mesh Refinement Dynamics

With the upcoming release of mf6Voronoi v0.0.38, optimizing mesh generation workflows remains a top priority. Constructing complex unstructured Voronoi grids for MODFLOW 6 can become computationally intensive as spatial resolution increases. To address this challenge, parallel execution capabilities were introduced into mf6Voronoi leveraging dask-geopandas.

Automatic calibration of pumping test data with MODFLOW6, Model Muse and Pest - Tutorial

This tutorial walks hydrogeologists through the full workflow of automatic calibration of pumping test data using MODFLOW 6, ModelMuse, and PEST. A real pumping test scenario — comprising a 6-hour pumping phase and an 18-hour recovery phase — is set up in ModelMuse, where the well is conceptualized as a Multinode Aquifer Well (MAW) boundary condition to accurately represent multilayer aquifer interactions. PEST is then implemented to automatically estimate key hydraulic parameters including hydraulic conductivity, specific storage, and specific yield, eliminating tedious manual calibration and delivering reproducible, optimized results. Whether you're new to parameter estimation or looking to streamline your existing workflow, this tutorial offers a practical, hands-on guide to modern groundwater model calibration.

Regional example of seawater intrusion modeling with MODFLOW6 and mf6Voronoi - Tutorial

This is an applied example of seawater intrusion modeling using MODFLOW6 and the BUY package. The model is fully geospatial and works with ESRI Shapefiles and rasters (*.tif) as inputs. The model grid is based on Voronoi meshes generated with the Python package mf6Voronoi. Since there are so many concepts involved in the conceptualization of a variable density groundwater flow simulation with MODFLOW6 and Flopy, these cases use a code template from mf6Voronoi that simplifies the model construction and simulation. The applied case also gives us the chance to discuss the main parts of model setup.

Simple example of construction site drainage modeling with MODFLOW6 and mf6Voronoi - Tutorial

In mf6Voronoi horizontal flow barriers can be modeled as low k cells with thickness of 1m without compromising the cell amount and model performance. We have developed an applied case of construction site dewatering using horizontal drains and pumping wells that work in parallel over a period of 8 days. The model shows the performance of the drainage schema and exports the final water table as raster and contours.

Inflow modeling to infiltration galleries with MODFLOW6 and mf6Voronoi - Tutorial

Infiltration 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.
