IAHR World Congress
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.
#iahrWorldCongress
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.
Forthcoming
41st IAHR World Congress "Innovative Water Engineering for Sustainable Development"
22-27 June 2025. Singapore
The 41st IAHR World Congress will focus on the importance of innovative water engineering towards meeting the Sustainable Development Goals (SDGs) and targets related to water resources.
The Congress will showcase the role of expert knowledge by the hydro-environment engineering community to the implementation of innovation solutions to meet the SDGs, and share insights on research, technology and innovations that will create significant impact to tackle global challenges such as climate change and sea level rise.

Testimonies
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.
Simone Pagliara, ETH Zurich, Switzerland
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.
David Ferras, IHE Delft, The Netherlands
My first IAHR congress was amazing. In Granada, I have met my peers from every side of the world, sharing their knowledge and discoveries in water sciences. I also presented my #phd #research in front of this outstanding audience and received good feedback and useful tips. See you at the IAHR2023.
Daniele Catucci, University of Nottingham, UK
What a conference the IAHR World Congress in Granada!! I'm still recovering... It was a pleasure to meet old and new colleagues, share the initial results of my postdoc research, and lead the fun activity within the #YPNight with the rest of the directive of the SpainYPN.
Manuel Regueiro, Universidade da Coruña, Spain
This conference was fantastic—I met many amazing scientists and engineers who I can now call friends, and maybe even collaborate with in the future.
Hannah Spero, University of Notre Dame, USA
I've met a lot of outstanding engineers, scientists and enthusiast young professionals, that opened my mind with their inspiring presentations and posters. It was nice to see that in this crucial moment for the water sector, research community and design industry are working together to deliver a better world to the next generations.
Matteo Ventura, Italferr spa, Italy
Last week, I took part to the 39th IAHR World Congress in Grenada (Spain). This was my first in-person international conference and the perfect opportunity to meet some of the best researchers in the water field. Also, I created connexions with other research institutes and made great new friends.
Vincent Schmidtz, University of Liège, Belgium
I am flattered to have attended the sessions and share my work with high level academics and experienced professionals.
Marcelo Ruiz, Universitu of Padua, Italy
It was a pleasure to present part of my Ph.D. activities at the IAHR World Congress in Granada and an honor to be selected for the final round of the John F. Kennedy competition, where I met so many talented young researchers involved in water sciences.
Melissa Latella, Politechnic of Turin, Italy
Just leaving Granada, but really beautiful experience at IAHR World Congress, with nice presentations and cool exchanges with many researchers there. Hope to replicate soon!
Matteo Postacchini, Universita Politecnica della Marche, Italy
I enjoyed immensely the IAHR World Congress in Granada. After being an IAHR member for 33 years, that was my first World Congress.
David C. Froehlich, Ph.D., P.E., D.WRE, USA
It was a real pleasure to attend and present our research with my research group at the 39th IAHR World Congress in Granada. It has also been inspiring and enlightening to meet pioneer researchers and to listen to the interesting work presented.
Tewelde Hagos Gebremedhin, PhD candidate in Civil and Environmental Engineering, Ethiopia
The 39th IAHR World Congress was my first in-person international conference and the perfect opportunity to meet some of the best researchers in the water field. Also, I created connections with other research institutes and made great new friends.
Fawaz Alzabari, Cardiff University School of Engineering, UK
The 39th IAHR World Congress has been a unique experience both from a scientific and social point of view. Several key note lectures and high level panels have been very inspiring. Thanks to the sociable environment, I had the chance to meet and speak to several peers and mature researchers. It was interesting to discuss our projects and ideas at the congress, as well as have informal chats while enjoying tapas after a long day. Granada was the perfect framework for this conference. The beauty of the city made my stay even more pleasant!
Tommaso Attili, University of Nottingham, Faculty of Engineering
Like most of the other PhD students I met at the congress, this was my first in-person conference. For me, it was a fantastic experience. The opportunity to present among other exemplary speakers from diverse backgrounds and the additional attention this garnered all helped me in my time at the conference introducing me to a wide variety of people both young and experienced professionals. The conference experience was excellent, with the city of Granada offering vast amounts of scenery, good food, tapas, and culture. I am very glad to have gotten the opportunity to meet so many interesting and impressive people at the congress having made friends and connections I hope to hold on to going forward, perhaps we will all see each other next year in Vienna!
Nicolas Hanousek, Cardiff University School of Engineering, UK
I had the pleasure to attend the 39th congress of International Association for Hydro-Environment Engineering and Research (IAHR) in Granada. Meeting peers from all around the world was very interesting and instructive!
Juliette Mullineaux, Cardiff University School of Engineering, UK
I had an amazing time at the IAHR 2022 World Congress in Granada last week. Additionally, the weather and food in Granada was fantastic. All in all the conference was a big success.
