Introduction to Applied Groundwater Flow Modelling with GW Vistas (March-May 2025)
Groundwater Modeling. The training course Introduction to Applied Groundwater Flow Modeling will take place at the SYMPLE school in Vetralla, Italy, with the option of participating online. The course is divided into three parts: the first is theoretical and entirely conducted online, the second part is a blend of online and on-site attendance, emphasizing practical applications of MODFLOW models. A final session, focused on a pumping test analysis and a dewatering project, will commence on-site and continue online later on.
The course will cover essential practical criteria necessary for constructing a numerical flow model. This includes topics like defining parameters, boundary conditions and inputs, both in stationary and transient conditions. Practical applications using MODFLOW packages will be demonstrated through explanatory lectures and computer exercises facilitated by the proprietary GUI Groundwater Vistas 8. Each participant will have access to Groundwater Vistas for a duration of 2 months.
To ensure accessibility and flexibility, all course sessions, whether conducted online or on-site, will be recorded. These recordings will be uploaded to our e-learning platform, allowing participants to review the material at their convenience.Price: 600

Glaciers and Groundwater Interactions: Challenges in a Changing Climate
Melting snow and ice from mountains are critical for freshwater supply in many regions. However, the interactions between glaciers, groundwater and permafrost remain under-researched, particularly within the context of a changing climate. In this webinar, high-level scientists from the International Association of Hydrogeologists will present an overview on the issues surrounding research into this topic, as well as demonstrating the importance of groundwater in storing glacial meltwater by presenting two case studies. Panellists have also been invited to discuss future solutions and research needed on this crucial topic.

22 Mar 2025
World Water Day 2025
Glacier Preservation. World Water Day, held on 22 March every year since 1993, is an annual United Nations Observance focusing on the importance of freshwater.
World Water Day celebrates water and raises awareness of the 2.2 billion people living without access to safe water. It is about taking action to tackle the global water crisis. A core focus of World Water Day is to support the achievement of Sustainable Development Goal 6: water and sanitation for all by 2030.
Every year, UN-Water — the UN’s coordination mechanism on water and sanitation — sets the theme for World Water Day. In 2025, the theme will be Glacier Preservation.
IAH is hosting a webinar to celebrate on World Water Day on 21st March - find out more at: https://iah.org/events/glaciers-and-groundwater-interactions-challenges-in-a-changing-climate.Organised by UN-Water.

6-27 May 2025 – Online
Undressing MODFLOW
Groundwater Modeling. This short course focuses on how to understand and modify MODFLOW 6 input and output files. The course will also touch on files that are read/written by other members of the MODFLOW family (MODFLOW-USG and MODFLOW 2005).
Why should you care about the contents of MODFLOW input and output files?
- Firstly, programs that write MODFLOW input files for you (such as graphical user interfaces and FloPy) sometimes either make mistakes, or do not understand your intentions. In the end, the only way that you can be sure that MODFLOW is receiving the information that you want to provide to it is to check these input files yourself. Also, if MODFLOW is behaving strangely and you are not sure why, the answer will probably be found in the data that it is being given. The only way to be sure of what data it is being given is to scrutinize its input files.
- Secondly, what if you need to provide some inputs to MODFLOW, and/or process some MODFLOW outputs, in ways that your GUI or other software does not support? You need to know MODFLOW’s input and output protocols to do this. All of these protocols are well-documented. This gives you the freedom to do whatever is best for you.
- Then there is PEST/PEST++. These can be used for history-matching and uncertainty quantification of a MODFLOW model, as well as for other tasks such as management optimization (under uncertainty). Members of the PEST/PEST++ suites interact with MODFLOW through MODFLOW’s input and output files. If you want to understand what these programs are doing, or create PEST-to-MODFLOW interactions that enhance history-matching and uncertainty analysis for your specific problem, then you need to understand MODFLOW input and output files.
The course is run by John Doherty (author of PEST) and involves three sessions of three-hour duration. These sessions would be interactive so that you can ask as many questions as you like and additional meetings can be arranged if more time is required.Price: 350
