The International Association of Hydrological Sciences (IAHS) is a non-profit non-governmental scientific organization committed to serving the science of hydrology and the worldwide community of hydrologists. The IAHS was established in 1922, and presently claims a membership in excess of 5000, from over 130 countries. [1]

Ten international scientific commissions deal with the hydrological cycle, water resources, and specific techniques.[2] Other working groups and initiatives address particular issues.


IAHS is one of the eight associations that comprise the International Union of Geodesy and Geophysics. In accordance with the IAHS statutes and by-laws, the IAHS officers and commissioners are elected every four years by national representatives at IAHS assemblies.[3]

National representation[edit]

Official contact between the IAHS and member countries is via the national representative in each country who acts as a focal point and channel for communication. If there is a national IUGG committee (usually appointed by the national academy of sciences or equivalent), the IAHS representative is nominated by it, or its IAHS subcommittee.[4] Member countries may also appoint national correspondents of the Commissions.[2]


IAHS Press fulfills the IAHS mission of worldwide dissemination of research results and practice, and raises funds, by publishing and selling the Hydrological Sciences Journal[5] and Benchmark books.[6] The IAHS Newsletter is distributed free to members..


IAHS is a UK registered charity; all revenues are used to support the aims of the Association. The greater part of IAHS’ funding is raised through the sale of IAHS publications.

IAHS works closely with IUGG, International Council for Science (ICSU), UNESCO, World Meteorological Organization (WMO), International Atomic Energy Agency (IAEA) and WWC, and often collaborates with organizations such as International Association of Hydrologists (IAH), International Association of Hydraulic Engineering and Research (IAHR) and Inland Waterways Association (IWA).
