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

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

LUWQ2025 Conference
Landuse and Water Quality Conference. LuWQ2025 – International Conference on LAND USE and WATER QUALITY: Agriculture and the Environment
LuWQ20125 is an interdisciplinary conference on the cutting edge of science, management and policy to minimise effects of agriculture and land use changes on the quality of groundwater and surface waters. The conference aims to discuss the entire ’policy cycle’ to enable enhancing the quality of the water environment, which includes problem recognition, formulation of technical options, policy formulation, interaction between policy makers and stakeholders (i.e. pressure groups), policy implementation, monitoring and research. The key strength of the conference is twofold. On the one hand, LuWQ has a well-defined narrow focus on ‘agriculture and water quality’. On the other hand, the conference is broadly oriented with regard to the various professional disciplines related to the conference topics. Based on the experience from previous Land use and Water Quality editions, it is the diversity in professional background of participants which results in a multi-faceted conference program. Consequently, LUWQ offers sessions on a broad variety of topics, all of them however dedicated exclusively to agriculture and water quality.
The objectives are:
- to provide a forum for exchange of scientific knowledge, research to better understand ’systems function’, modelling and uncertainty;
- to discuss the entire policy cycle for water quality improvement; and
- to intensify contacts (a) between soil/water related scientists, agro related scientists, social scientists, ecological scientists and economists, and (b) between scientists, water managers and policy makers.
The conference themes and topics are characterised by the following keywords: water management, water policy, hydrology, aquatic ecosystems, terrestrial ecosystems, unsaturated zone, groundwater, surface waters, drinking water, monitoring, modelling, water quality, nutrients, pesticides and other organic agrochemicals, heavy metals, agronomy, agro-economics, agro-sociology,.
Conference is jointly convened by:
• RIVM, National Institute for Public Health and the Environment, the Netherlands
• DCE - Danish Centre for Environment and Energy, Aarhus University, Denmark
• Department of Ecoscience, Aarhus University, Denmark
• Geological Survey of Denmark and Greenland (GEUS), Denmark
• Forschungszentrum Jülich (FZJ), Research Centre Jülich, Germany
IAH is Scientific Sponsor of the conference.
