12 Mar - 24 Apr 2026 – Vetralla (VT), Italy
Introduction to Applied Groundwater Flow Modeling with GW Vistas
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: 800 euro

World Water Day 2026 – Water & Gender
Where water flows, equality grows
The global water crisis affects everyone – but not equally.
Where people lack safe drinking water and sanitation close to home, inequalities flourish, with women and girls bearing the brunt.
They collect water.
They manage water.
They care for people made sick by unsafe water.
They lose time, health, safety, and opportunities.
And too often, the systems that govern water leave women and girls out of decision-making, leadership, funding and representation.
This makes the water crisis a women’s crisis.
We need a transformative, rights-based approach to solving these challenges, where women’s voices are heard and their agency recognized.
All women must be equitably represented at all levels of water leadership – helping design every pipe and policy.
And women must drive change in water as engineers, farmers, scientists, sanitation workers and community leaders.
As we face growing risks, from a changing climate and water-related disasters to financing shortfalls, from social norms to governance gaps, we need everybody to play their full part: managing water as a common good and building resilience for the future.
This includes engaging men and boys as allies in promoting safe water, sanitation and hygiene for all, and in challenging the norms and behaviours that hold women and girls back.
Only then can safe water services meet everyone’s needs – empowering women and girls to lead healthier, more fulfilled lives – and making water a force for sustainable development and gender equality that benefits us all.
On World Water Day 2026, let's explore the critical relationship between water, women, and gender equality.Organised by UN-Water.

IAH (Irish Group) Technical Discussion Meeting
Groundwater and coastal carbon dynamics. IAH Ireland Group Technical Discussion Group Meeting
Alex Cabral, Trinity College Dublin: Groundwater and coastal carbon dynamics
More details here: https://www.iah-ireland.org/upcoming-events/
This talk examines how groundwater transports carbon and nutrients from terrestrial landscapes to coastal marine waters, shaping water chemistry and greenhouse gas emissions. Such groundwater-driven fluxes are often difficult to detect but can represent a significant overlooked component of coastal carbon budgets. A combination of radioactive tracers and stable isotopes is used to identify hidden groundwater flow pathways and to quantify associated solute fluxes along the land–ocean continuum. The findings highlight how geological structure and hydrological connectivity regulate groundwater-derived carbon and nutrient inputs to coastal ecosystems, with implications for coastal biogeochemistry and primary productivity.Price: free

15-17 Apr 2026 – Milan (Italy)
Time series modeling of Groundwater levels with Pastas
Groundwater time series analysis using impulse response functions, with hands-on exercises using the open-source Python package Pastas. The term aquifer derives from the Latin aqua ferre, meaning “to carry water”. Embedded in this definition is the concept of movement, and therefore of time. Groundwater systems can be seen as living systems, continuously responding to external solicitations such as recharge, evapotranspiration, pumping, and surface water interactions. Groundwater level time series represent the integrated signal of these stresses, filtered by the physical properties of the aquifer. Today, large amounts of monitoring data are routinely collected through automated measurements, yet a significant portion of these datasets remains largely unused. Groundwater levels are recorded, archived, and reported, but often not analysed in a way that extracts the information contained in the signal itself. This represents a loss of precious knowledge, essential for informed groundwater management.
Time series analysis provides a framework to study aquifer response without requiring a complete physical description of the subsurface. Through a data-driven approach, the observed signal can be decomposed into the contributions of different processes controlling groundwater dynamics, quantify response times, and support management decisions. For a more detailed overview, see: Bakker and Schaars (2019). In many cases, attempts to reproduce complex realities through highly detailed physically based models may lead to over-complex numerical models with limited predictive capability, whereas time series models focus directly on reproducing and interpreting observable system behaviour.
This workshop introduces groundwater time series analysis using impulse response functions, with hands-on exercises using the open-source Python package Pastas. Participants will learn how to use Pastas to describe and predict groundwater level fluctuations.Price: 300-600euro
