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.

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.

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.
