6 -10 September 2021 Brussels, Belgium 5 DAYS 6 - 10 September 2021 Brussels, Belgium 5 DAYS

The year of 2021 is highly anticipated: it is the year after the 2020 Covid pandemic affected our planet. We all hope this world crisis will be behind us in 2021 and we can hold a double congress celebration.

For us hydrogeologists, 2021 will see

  • the 47th IAH CONGRESS held in Brazil on August 22nd – 27th
  • and the 48th IAH CONGRESS in Belgium on September 6th – 10th.

Two congresses for IAH’s 65th Birthday!

Both committees are working together to bring you coordinated events.

Please note that:

  • The General Assembly of the members of the IAH and the Council Meeting of 2020 will be held online – more details to come from IAH
  • For 2021, these meetings will be organised in Brussels, Belgium, during the 48th IAH Congress in September
  • The IAH Commissions, Networks, Working Groups and National Chapters will choose where to hold their meetings in 2021

Stay tuned !

Dear Water Experts

In September 2018, in Daejeon, South Korea, the Council of the IAH decided to appoint the IAH Belgian National Chapter (the CBH-BCH) to organize the 48th International Congress of 2021.
It’s a great honor, a wonderful pleasure and an exciting challenge to organize such an event.

So there we go

The congress will be held in Brussels, Belgium, from September 6-10 September, 2021, in the very heart of the Belgian and European Capital.

Brussels, Belgium
Monday to Friday
6 – 10 September

The History of the world shows us that water and groundwater have constantly inspired Mankind to develop techniques for the production of drinking water, to transport water to people, to control and manage watercourses, to the search for new sources, to combat scarcity. Access to safe water in sufficient quantities is essential to Mankind, to prosperity and economic development

  • Let the past inspire us to prepare a better future.
  • Let our failures inspire us to constantly improve our techniques.
  • Let research inspire us to turn challenges into opportunities, and to make groundwater part of the solution towards a society without fossil energy sources.
  • Let  our children inspire us to give our grandchildren a better planet

In 2021, we’ll also celebrate together the 65th anniversary of the IAH … and the 20th anniversary of our chapter. Did you know that the first president of the IAH was Belgian ?
Belgium is a small country, but we have a lot to give… To the organization of the congress, we’ll also do our best to make you discover some aspects of our culture, of our history, of our architecture, of our gastronomy.

You are all welcome to join us and to learn from others, to exchange and to transfer knowledge, to learn to know people, to build solutions.

Brussels, September 6th : we’ll be there. Will you ?

Follow us here for more information in the coming months.
