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 MoreThe task to modify geospatial rasters considering future elements can be a complex task with the available GIS tools. 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.
Read MoreMODFLOW6 with mf6Voronoi can handle the simulation of specific tasks related to the mine industry. 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.
Read MoreOne of the key objectives from groundwater modeling in mining is the determination of pit inflows and the extension of the depression cone. 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:
Read MoreThis applied case presents a step-by-step methodology to simulate groundwater inflow into an open pit using MODFLOW 6—the groundwater flow modeling engine developed by the USGS—in combination with mv6Voronoi, a tool that generates Voronoi meshes.
Read MoreBecause 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.
Read MoreThere is a plugin for Visual Studio Code that improves MODFLOW 6 model readability. The installation process is quite easy and works for any model without any additional setting or command. This is an applied case of the plugin installation and exploration of a MODFLOW 6 model for a andean basin.
Read MoreAn applied example of modeling the development of underground mine works with time based on a Voronoi mesh MOFLOW 6 model. The case consists of 5 mine levels developed over 5 years that cross the underground water body at determined lengths. The numerical model is developed with Python, Flopy and Mf6Voronoi for spatial discretization, implementation of the boundary conditions based on geospatial data, model build/simulation and 3d representation on Paraview.
Read MoreBasic example of MODFLOW 6 groundwater flow modeling with Flopy. The model is multilayered and runs on transient conditions with the recharge, well and river boundary conditions implemented. The example also load model results and create head distributions with flow direction plots with Matplotlib.
The example runs entirely on the Google Colab platform with the use of a Github repository with the MODFLOW 6 executables. This workflow is intended to give a complete online experience of groundwater modeling without any particular computer/software requirement.
Read MoreElevation 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.
Read MoreBesides doing amazing tutorials in groundwater modeling with MODFLOW and Flopy we also have the most complete set of Flopy courses applied to different areas of groundwater resources evaluation and impact assessment. But, there is more: we have a whole program that trains you from zero knowlege of Python to develop fully featured groundwater flow models.
Read MoreA practical example for constructing a geological model using Python and Aquifer App, based on geospatial data in ESRI Shapefile format and raster data in Tiff format. The tutorial demonstrates the complete procedure of spatial data processing using libraries such as Geopandas, Rasterio, and Pyvista to create surface and orientation files, which are then input into Aquifer App. Finally, the project is run locally in Gempy, generating the geometry of lithology and contacts.
Read MoreThis is an applied case were we build a geological model only with lithology information stored as a point shapefile. The tutorial covers all steps from raster (array) generation for all surfaces together with the orientation sampling and format of surfaces/orientations as Gempy input files. The generated data was inserted in the Aquifer App that implements an interface to create Gempy models. Finally the lithology and layer surface geometry was exported as Vtk to be represented on Paraview with the initial data to evaluate the accuracy of the simulation.
Read MoreAquifer App offers a friendly, clean and powerful way to create Gempy scripts for geological modeling. We have developed an applied case of a 3D petroleum system model for a part of the Williston Basin, USA that contains the Nesson Anticline. Top layer information was provided as raster format where elevation and orientation for random points were extracted with Python codes using the Gemgis package and exported in Gempy input file format. On Aquifer App the processed CSV files were inserted and the geological model was set up with the corresponding geological sequence.
