44th IAH Congress, Dubrovnik, Croatia


The Regional Groundwater Flow Commission co-organized a session at the  44th IAH Congress titled Groundwater management and energy source development in a changing climate (T 1.2). The oral and poster sessions attracted several contributions in a wide range of topics including surface water-groundwater connection, managed aquifer recharge, groundwater management, numerical and geochemical analysis and predicted effects of climate change. The session was conveyed by Ádám Tóth (Eötvös Loránd University, Budapest, Hungary, RGFC Secretary) and Roland Barthel (University of Gothenburg, Sweden).

Regional groundwater theory was also present at other topics and sessions such as karst hydrogeology, hydrochemistry of thermal and mineral waters and groundwater-dependent ecosystems. During the social events and breaks, the Commission offered willingly its support to the organisers of the upcoming IAH Congress held in Daejeon, South Korea.

The representatives proposed some topics and possible sessions to enrich the Korean Congress. The details of the planned CRC blue book was also discussed with Janjaap Blom (CRC Press). The need of cooperation between Groundwater and Energy and Regional Groundwater Flow Commissions was realized as well.

Characterizing regional groundwater flow systems: Insight from practical applications and theoretical development, 26–28 June 2017, Calgary, Canada

Calgary Symposium was organised by the Regional Groundwater Flow Commission in cooperation with the Canadian National Chapter of IAH. The two-day-long Symposium had altogether 65 oral and poster presentations and 2 keynote lectures: Okke Batelaan had a talk about the past, present and future of flow systems, and Grant Garven presented geofluids leakage along an active plate boundary. Distinguished guest Prof. Joe Toth – claimed himself as the dinosaur of hydrogeology – summarised the takeaway message of the fruitful and scientifically rich Symposium: „The theory is very much alive and it is broadening”.

EGU General Assembly 2017

Our Commission co-organized a session entitled “Groundwater Vulnerability and Circulation” at the European Geosciences Union (EGU) General Assembly 23-28 April 2017, Vienna, Austria. The session attracted 6 oral presentations and 18 posters. During the oral presentations, around 40 people attended the session. The session included a broad range of techniques such as hydrochemistry, environmental tracers, and numerical modelling. These methods have been applied in countries in Europe, Asia, America and Africa to examine groundwater vulnerability and circulation problems.

Session conveners: Xiaowei Jiang, Judit Mádl-Szőnyi, Manuela Lasagna, Daniela Ducci and Jim LaMoreaux

Visit of Joel Carrillo-Rivera in Budapest

Prof. Carrillo-Rivera had an academic visit 24-31 March 2017 in Budapest supported and financed by the Hungarian Ministry of Foreign Affairs and Trade. He had a talk on Groundwater law proposal for Mexico at the Directorate of Water Management of Hungary. In the frame of József & Erzsébet Tóth Endowed Hydrogeology Chair, Prof. Carrillo-Rivera gave a short course entitled Groundwater flow systems and vertical flow, which was attended by master and PhD students of the Eötvös Loránd University.
