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.

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 MoreYou 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.
Read MoreThere is a new dataset from the European Space Agency (ESA) called Copernicous DEM (GLO-30) that has global coverage with raster resolution of 30m available to download from the Copernicous Dataspace. We have prepared an applied case to access this dataset, download and clip for an area of study and process it into Hatari Utils that provides the watershed and river network delineation on spatial format. The example also covers the options to determine the accumulation area and explore other outputs from the platform.
Read MoreThis example develops a groundwater model in MODFLOW6 DISV that implements a Voronoi mesh generated from the basin boundary and river network with the mf6Voronoi packages that allow high performance meshing fully coupled with geospatial data. On the Voronoi mesh, the refinement levels are defined by a minimum cell size, maximum cell size and a multiplier. The applied case covers all steps on model discretization, construction, simulation and 2D visualization.

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 MoreLithium 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.
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 MoreGroundwater modeling with several boundary conditions and complex hydrogeological setups require advanced tools for mesh discretizacion that ensures adequate refinement in the zone of interest while preserving a minimal cell account. Type of mesh has to be engineered in a way to preserve computational resources and represent adequately the groundwater flow regime.

HEC-ResSim is a tool that supports reservoir simulation models, aiding decision-making for improved reservoir operations. The nature of HEC-ResSim, its flexible framework for describing reservoir operations, and its new and powerful features make it applicable for modeling almost any multi-purpose storage system. The approach used by HEC-ResSim is based on rules to replicate the operational decision-making followed by reservoir operators. For water release processes from the reservoir, HEC-ResSim considers variables such as the time of year, hydrological conditions, water temperature, and simultaneous operations with other reservoirs within the system.
This tutorial covers an applied case of reservoir modeling at the discharge point of an andean basin. The example covers the steps to set up the watershed, define the reservoir network, simulate the hydrological alternative and explore output hydrographs and tables.
Construction of complex and high performance groundwater modes requires an appropriate distribution of the hydrogeological units with depth. We have developed an applied case of 3D modeling of hydrogeological units from data provided as raster (*.tiff) files. The webinar all steps from orientation and elevation sampling from raster data, the conceptualization and setup of the Gempy model in Aquifer App and finally the postprocessing of the 3D lithology based on the surface elevation. The input data comes from the USGS research on the aquifer Systems in the Williston and Powder River Structural Basins, United States and Canada.

Boundary conditions are also set up from spatial data with the intersect functionality of Flopy. Model surface and layer bottom are imported / processed from xyz point data. The simulation is run for one steady and ten transient stress periods and results are plotted for head on aerial view and cross section.
Read MoreIn order to improve the accuracy of a groundwater flow simulation we need a strong conceptual model, a high quality observation dataset and a numerical code that can handle specific characteristics of the groundwater flow we want to evaluate. MODFLOW 6 can deal with variable density flow with the BUY package and also with variable viscosity with the VSC package that is implemented on the latest versions of Model Muse. This tutorial covers an applied case of variable viscosity modeling due to the injection of salinity and heat to a model with regional groundwater flow. The main features for the implementation of the VSC package are explained and the resulting concentrations on two observation points are evaluated with Flopy codes.
