The Working Group on Transient Flows of the International Association for Hydro-Environment Engineering and Research (IAHR) and the Technical Committee on Hydraulics of the Brazilian Association of Water Resources (ABRHidro) invite you to attend the International IAHR Meeting on Transient Flows, which will take place from 25 to 26 November 2025 in Vitória, Brazil, in conjunction with the XXVI Brazilian Symposium on Water Resources.

The initiative for a themed event originated at the 2023 IAHR World Congress in Vienna, Austria. Aligning this meeting with the Brazilian Symposium presents an excellent opportunity to strengthen an event envisioned by the Working Group on Transient Flows. This setting will allow for a broader presentation and discussion of key topics relevant to members, fostering greater participation and engagement.

Vitória, the capital of the Brazilian state of Espírito Santo, is in the vibrant south-eastern region of Brazil. The city is one of three Brazilian capitals located on an island and is recognized for its tranquillity and quality of life.

On behalf of the Organizing Committee, we thank you for your participation and invite everyone to engage actively in our program, which promises moments of learning, connection, and inspiration.

Welcome to the International IAHR Meeting on Transient Flows!
