Based on a coupled workflow on QGIS and Python it is possible to extract the required information for a Gempy model and run it for defined voxel sizes. This tutorial covers the whole procedure of spatial data preparation, data preprocessing in defined formats and geological modeling with Python and Gempy.
Read MoreWe have done an applied groundwater model for a pumping test on a confined aquifer. The wellsite is located on the Clairborne aquifer (Georgia, USA) and has two observations on different layers besides the well itself. The aquifer test has two periods of pumping and recovery that last 3 days each one and the numerical model was constructed with MODFLOW-6 based on a Python script with the FloPy package. Comparison among observed and simulated wells were done with plots in Matplotlib.
Read MoreGenerating 3D visualizations of groundwater models is essential to analyze the flow regime, perform quality checks and see the interaction of the groundwater body with external factors / boundary conditions. The Flopy library has tools to export the parameters, boundary conditions and results that we have modified and compiled within a Python class. The use of this class allows the generation of Vtk files on a friendly way and in few steps. The tutorial also includes a representation of the parameters generated in ParaView.
Read MoreModflow on parallel processing seemed to lie in the far-off future, but now it’s possible to take advantage of most of your cores to run parallelized versions of MODFLOW 6. Since most MODFLOW modelers work on Windows we wanted to bring something more than a “packed” solution; our goal was to bring an enriched “packed” experience.
Read MoreLithium interaction with the aqueous phase on brines phase is not well understood or at least not well covered by the scientific publications. To evaluate brine composition, brine dynamics and the interaction of the different components is really a challenge with the available tools for geochemical modeling as Phreeqc since it doesn’t appear in all the databases and in most it is only associated with sulfates.
Read MoreIf you want to speed up some steps in groundwater modeling you might be interested in the tools presented on this tutorial. We have developed some online tools that replace intense and time consuming tasks on desktop software and web servers and provide vector and raster data on the formats required by Model Muse. The tutorial covers the steps of DEM generation as Surfer Grid File (*.grd) with the definition of watersheds and river network based on two online services provided by Hatarilabs.
Read MoreModflow 6 has changed in many ways the traditional concepts of groundwater modeling; now a group of models can run under a "simulation" and these models can interchange flow and transport. Under this structure Flopy has implemented a tool to split a groundwater model into several models where their results can be reconstructed and compared to the original entire models. Capabilities and features like this make Flopy and Modflow 6 a great tool for developing advanced groundwater models that simulate complicated tasks or requirements to the groundwater flow regime.
Read MoreIf you work often with numerical models this process will save you much time. The traditional method of downloading elevation models (Aster DEM) from websites, and reprojecting / clipping them with GIS software can be time consuming and pulls you out of other critical tasks on model conceptualization and calibrations. We have done a complete process in Python under WSL that runs Ubuntu in Windows, this platform was chosen due to the complexities of installing GDAL in Windows.
There are two scripts, one to download the images and the second to translate and clip the image. Finally the elevation are imported as a Surfer Grid File (*.grd) into a model in Model Muse.
Read MoreModel Viewer is an excellent option for the visualization and even the animation of MODFLOW models. There is a version of Model Viewer for Modflow 6 models and another for the rest of MODFLOW versions. This tutorial deals with the whole procedure of 3d model visualization that covers the model import, setting up the vertical exaggeration, making isosurfaces, show flow direction arrows, plotting boundary conditions among other features of Model Viewer.
Read MoreGroundwater model creation requires a complete set of spatial data for the different hydraulic parameters, boundary conditions and other model items. Vector and raster data need to be preprocessed, converted, reprojected to fit the requirements of Model Muse.
This tutorial covers an applied case of raster and vector data processing for a groundwater model over the Oahu island (Hawaii, USA). The tutorial covers the steps to download the data, extract the river network and import the spatial data into Model Muse.
Read MoreFinally, a complete alternative for the simulation of seawater intrusion on fully geospatial groundwater flow models of coastal aquifers based on open source software. The groundwater flow model was constructed on the Tupac Cloud platform with two stress periods and a total simulation time of 40 years.
The Tupac project is downloaded and run locally on Anaconda where the Buy package for variable density flow together with the transport model are implemented on a Flopy script. A graphical representation of the grid, boundary conditions and results from the flow and transport models are developed as well on the Jupyter notebook.
Read MoreApplied case of regional groundwater modeling for a coastal aquifer with Modflow 6 using Voronoi meshes on Tupac Cloud. The aquifer has two stress periods (steady state and transient state) of 20 years each that simulate two phases of low/high aquifer exploitation. The model is constructed entirely from zipped shapefiles and rasters on the online platform. Results from the simulation are discussed on the water balances, water table distribution and cross section for all stress periods.
Read MoreTupac Cloud is based on Python and Flopy and every project can be downloaded to your machine for special analysis, furter Modflow 6 feature implementation, machine learning based calibration, or just because a local backup copy is required. This tutorial shows the complete procedure to download a Tupac Cloud project, the executable implementation, the scripts to run the flopy code and well as a description of the different files and folders from a model project.
Read MoreThis is an applied example of the impact trough time of a tunnel over the regional groundwater flow regime. The model has 5 stress periods with two variants of the drain (DRN) package implemented in Tupac Cloud. The tutorial covers all steps from model construction, boundary condition setup, model run and output data analysis.
Read MoreApplied case for the evaluation of a drainage schema on a construction site with Tupac Cloud. The model has three stress periods where the drainage schema starts with well pumping for 10 days and trench drainage with pumping for another 10 days. Results from the water balance were analyzed as well as the final distribution of head on the proposed construction site.
Read MoreLocal scale modeling of a 4 stage trench excavation on a coastal aquifer. The main objective of this modeling work is assessing the impact of the excavation on the nearby groundwater flow regime. The modeling work was done entirely with the tools, charts and tables from Tupac Cloud.

The whole project will have lot of tools and integrations with QGIS and Paraview, this is just an example of mesh generation for an applied case of river aquifer interaction.
Read MoreQuadtree refinements are available for Modflow 6 models in the latest versions of Model Muse. This tool can be inplemented for many spatial objects as points, lines or polygons where you can specify the refinement level for each layer separately. We have done an applied case of mesh refinement of a regional model where the river network, observation points and tunnel aligment were defined as refinement objects.
Read MoreModel Viewer for Modflow 6 was launched in April 2022 and it is a version of Model Viewer customized to display the features, grid and results of MODFLOW 6 models. We have done an applied case for the visualization of a MODFLOW 6 DISV model that has a voronoi mesh. The tutorial covers the steps to visualize the model grid lines, grid shell, isosurfaces, color grid, flow directions among other visualization options.
