Lastest developement in Tupac Cloud for the representation of head as contours and color grid. Both representations have a colorbar and title related to selected layer. Objects as boundary conditions and model mesh can be represented on the plots.

Developing a hydrogeological research project that considers groundwater modeling for a bachelor thesis or a master thesis requires you to take into consideration several topics, such as input data, hydrogeological knowledge and time to learn the software in order to provide a numerical simulation that reaches the objectives of your research project.

Learning a software for groundwater modeling should be easy as developing some tutorials and playing around with your own data; however it is not that easy since it involves the review of lots of documentation, have strong knowledge in hydrogeology and numerical modeling and deal with uncertainties and numerical unconvergences.

We usually received some emails and messages regarding basic or reference books and publications in Hydrogeology and we didn't have any reference of free and high quality material until we knew about the Groundwater Project. It´s true that we found the project website some months ago, but it was at the latest IAH conference where we had a presentation with a complete overview of the program.

A special concern arises from the gap between the stage of development of open source groundwater software and the actual capabilities of the common groundwater modelers (we mean, the main group of modelers). Even though we are passionate about software we don’t find the time or the right momentum to have a real experience with those codes.

From our research, we have listed the top open source groundwater software with a brief summary of the capabilities and useful links. We have to mention that there are some packages that can simulate groundwater flow in software like OpenFoam; however, those variants are not listed here.

In 2017, the U.S. Geological Survey released a new core version of the MODFLOW program. This new version, called MODFLOW 6 (the sixth core version), extends the core MODFLOW capabilities to include robust solutions for complex water table problems, support for generalized meshes with focused resolution within areas of interest, and support for multiple models and multiple types of models within the same simulation. In addition to the Groundwater Flow Model, MODFLOW 6 now contains a Groundwater Transport Model, which can run simultaneously with the flow model or as a separate simulation using the results from a previous groundwater flow simulation.

Because field work and numerical models are just tools for the sustainable management of our groundwater resources we have searched a study place to develop a long-term project on a high-stressed aquifer that will lead to sustainable and effective groundwater policies. The study area is an alluvial aquifer that was primarily used for agriculture production with an neighboring unplanned urban development that has increased the domestic / industrial water demand. Several pumping schemas were implemented on the area and have affected the groundwater levels and the water availability for agriculture.

Development of open source software brings amazing new tools in all fields. In hydrogeology and groundwater modeling there is an increasing number of specific open source software and programming packages. We wanted to compile the latest libraries for Python related to hydrogeology, we asked for references and researched over the web to provide you the following list.
