Besides 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.

Read MoreSimulation of direct precipitation events over a surface is important to assess the impacted areas and manage disaster situations. Response to precipitation is evaluated over cells in a 2D model and runoff is routed to the stream networks. Landlab is a Python library for a variety of surface processes and can model shallow water flow over topography with a variety of algorithms. We have developed an applied case of direct rainfall for flood modeling over a geospatial raster where an initial water height is applied and then flows over the surface. Resulting water heights are exported as geospatial rasters.

Read MoreAn applied case for the recognition of missing crop vegetation areas based on a drone orthophoto. Contours have been identified from an enhanced combination of raster bands with a marching squares method to find constant valued contours and then exported as geospatial polygons.
Read MoreWatershed delineation and stream network determination are common tasks on the hydrological analysis for any area of interest. There is a parameter on the stream network determination that allows us to have simple stream networks that resemble the main water courses or dense stream networks that map all the permanent / temporary streams. This is an applied example of stream network determination on our online platform Hatari Utils where you can specify the number of upstream cells and interactively review the result.
Read MoreHydrological basins could have a diversity of shapes due to the morphology and it´s a challenge to have a process that can delineate basins with different characteristics in a short amount of time. Hatari Utils is an online platform for hydrogeological analysis that has a tool for basin delineation, in this tutorial we have tested the capabilities of Hatari Utils to delineate a basin that has an internal lake.
Read MoreEven though that the version 5.2 was released on March 22 2024 we just found time to make a video explaning the new features of this version and where they are implemented on the graphical user interfase. This new version of Model Muse allows to simulate variable density and variable viscosity flow among other features of Modflow 6. Have a look on the video and wait for our comming applied tutorials related to these new features.
Read MoreGempy is an open-source library for modeling geology written in Python. The library is capable of creating complex 3D geological models including structures, fault networks, and unconformities and it can be coupled with uncertainty analysis.
Hatarilabs have developed an online platform to create geological models with Gempy with minimal effort. The online tool is called GempyApp and runs under AquiferApp (aquifer.hatarilabs.com). This tutorial shows an applied example of geologic modeling of 4 layers with a fault. The tutorial covers the steps of point and orientation file input, definition of fault/strats and geological sequence, show data stats and tables, run the geological model interpolation and plot results.
Read MoreNo more installations, no more database link up, no more raw text data as model output. Aquifer App now can run Phreeqc with great tools for the geochemical model setup, database selection and tables / graphics for the different simulation components.
This applied example calculates the distribution of aqueous species in seawater and the saturation state of seawater relative to a set of minerals and is based on the Example 1 of the USGS Phreeqc example documentation.
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 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 MoreLet's have a look at the tutorial concept in its real dimension. A tutorial is a period of instruction that provides practical information about a specific topic. The tutorial can be given by an individual or institution and has a goal to teach you something or master you in something you didn't know before.
However in water resources software, we don’t see the tutorial as a part of the documentation or a key part of the learning experience. The tutorial is in fact an essential part needed to understand the whole capabilities of the software in practical exercises. It´s true that most software delivery exercises of different applied cases, but we can’t say they are tutorial in fact because those exercises lack a perspective of guided work.
