Implementation of Faults and Zone Budgets on a Open Pit MODFLOW 6 Voronoi Model - Tutorial

The 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.

Leaf Area Calculation from Drone Ortophotos with Python and Scikit-Learn - Tutorial

Besides counting crops we can also delineate plants and calculate its leaf area by using methods that fit open or closed splines to lines or edges in an image. These methods are implemented on the Python library Scikit-Image and applied for the delineation of tree canopies over a geospatial raster image. The exercise is developed in a Jupyter notebook and covers all steps from image import, apply grayscale,  explore gaussian filter, calculate active contour and export polygons as ESRI shapefile. Finally, there is an histogram generation to determine the distribution of leaf area from plants.

Create 3D objects (Vtks) from a groundwater model in Model Muse with mf6Voronoi - Tutorial

Model 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:

Paraview and mf6Voronoi for Modflow 6 model 3D visualization - Tutorial

Because an image is worth a thousand words, and 3D visualization is key for explaining, sharing, and analyzing groundwater model parameters, boundaries and results. 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. This is an applied case of 3D representation for a andean basin groundwater flow model where we are going to explore the relevant tools and options of mf6Voronoi and Paraview.

Accelerate MF6 Disv model creation using mf6Voronoi templates - Tutorial

You can work faster and have more time to analyze model results if the process of model creation takes less time. The design of the mf6Voronoi package is oriented to create an improved user experience by optimizing the options of mesh creation and by the implementation of Python script templates for meshing, model construction, and others. This is an applied case of groundwater modeling on a regional scale with Voronoi mesh built on MF6 Disv. The template can be easily customizable to other boundary conditions and will be the basis of coming tutorials and webinars.

Modeling Lithium brine pumping impact with Modflow 6 and Model Muse - Tutorial

Lithium is present in some salt lakes along with other brines in different concentrations. In order to simulate the right groundwater flow regime of Lithium brine along other brines we need to model variable density flow from multiple species. This type of modeling is possible on the latest versions of Modflow 6 with the BUY package and Model Muse.

We have developed an applied case of variable density flow modeling on a andean salt lake that is pumped from 3 wells in 10 years. The model has a grid refinement close to the lake and works with 6 brines: B(OH)3, NaHCO3, NaCl, KHSO4, LiHSO4 and NaHSO4. The example implements the BUY package with all the required parameters together with the configuration of the boundary conditions and initial conditions. Concentration and water balances are processed with Python to evaluate the brine migration over time and the impact of pumping on the water balance.

Topobathymetric elevation generation for flood modeling with geospatial Python

Elevation maps that represent surface and river bathymetry are an essential input for flood modeling in software like HEC-RAS. Even with the latest version of high profile open source GIS software as QGIS the combination of a surface elevation map and a river bottom elevation map is a challenge that requires many turnaround, conversion and manual labour. We have developed a useful script that works with surface and river bottom elevation in a "smart" way and creates a geospatial raster with the topobathymetric elevation by the use of geospatial Python libraries as Shapely and Rasterio. The script also includes some key steps to identify the river body and treat the missing values on the bathymetry map.
