The next Scientific Assembly of the International Association of Hydrological Sciences (IAHS 2021) will take place in Montpellier, France from 28 June to 2 July 2021. 

This important biennial event will provide an opportunity to communicate, exchange and project on all major topics in the hydrological sciences within the framework of sessions organized by all IAHS Commissions and Working Groups.

IAHS 2021 will have three major focuses:

·       Panta Rhei initiative (2013-2022) on change in hydrology and society

·       UPH initiative, "Unsolved Problems in Hydrology"

·       Launch of the 100th anniversary year of IAHS

This event will be accompanied throughout this week by many other "water-related" events for scientists, the general public and schoolchildren.
