About this event
Celebrated every two years, IAHR World Congresses are one of the most important activities of the association and attract more than a thousand participants from all over the world. The Congresses provide scientists, engineers, organisations, central and local authorities, companies, and young professionals early in their careers with a stimulating opportunity to meet, share and discuss recent advances and experiences, identify innovative and emerging trends in hydro-environmental science and engineering, and get inspired.
Under the theme: "Drive the Change: Management in the Era of Digital Water & Transitions", the congress will explore how cutting-edge technologies, innovative policies, and sustainable strategies are reshaping water management in a rapidly changing world.
I would like to congratulate the excellent organization an success of the 41st World Congress. It was an amazing experience to see the international water sector come together for a week to debate its future. I'm sure that new working bridges were established, innovations were shared and the sector was certainly strengthened.
My first IAHR world congress was an amazing experience, it was an honour to be selected as a finalist of the John F. Kennedy Student Paper Competition and to present many of the findings of my first year of PhD in front of so many outstanding researchers. Happy also to have met many talented young researchers involved in water sciences, I hope to see you all in Vienna IAHR2023.
IAHR association connects our scientific community at the highest level, above universities and institutes. To me that is the essence of an international research association. During these days in Granada there has been an immense exchange on main hydro-environment aspects as a result of the reunion between colleagues from all regions, ages and cultures. The World Congress provides this ideal framework and this 39th edition has been a great success.
