The General Assembly of IAHS held at Canberra in 1979 endorsed the principle of an International Hydrology Prize awarded annually on an individual basis in recognition of an outstanding contribution to the science. Nominations for the Prize are made by National Committees and forwarded to the Secretary General for consideration by the Nomination Committee. The Committee consists of the President and a Vice-President of IAHS and representatives of UNESCO and WMO. The following criteria are valid:
The International Prize in Hydrology shall be awarded to a person who has made an outstanding contribution to hydrology such as confers on the candidate universal recognition of his or her international stature;
The contribution should have an identifiable international dimension extending beyond both the country of normal work and the specific field of interest of the candidate;
The contribution may have been made through scientific work, as evidenced by the publication in international journals of scientific literature of a high standard, and/or through practical work, as evidenced by reports of the projects concerned. Preference should be given to candidates who have contributed through both scientific and practical work.
The Prize may be awarded to hydrologists of long international standing or to those who, while having gained such standing only recently, exhibit the qualities of international leadership in the science and practice of hydrology.
An active involvement in the work of IAHS and other international organizations in the field of hydrology should be counted as an advantage.
Nominations for the Prize should be received by the Secretary General no later than Dec 31 of the previous year.
The IAHS Tison Award was established in 1982 and aims to promote excellence in research by young hydrologists. The Award will be granted for an outstanding paper published by IAHS in a period of two years previous to the deadline for nominations. The following criteria are valid:
Candidates for the Award must be under 41 years of age at the time their paper was published;
The Award will consist of a citation in the name of L.J. Tison, an amount of US $1,000 and a free subscription to HSJ for one year. If the successful paper is jointly authored by eligible (age) authors, the monetary award will be divided equally between authors;
The Award will be announced annually and will be presented in a public ceremony, normally during either an IUGG/IAHS General Assembly or an IAHS Scientific Assembly;
Nominations for the Tison Award may be submitted by the National Committees of IAHS, officers of the IAHS Bureau, officers of the Commissions, HSJ editorial board members, convenors of IAHS symposia or editors of proceedings. The nomination may not be submitted directly by an author or co-author but may be submitted through one of the aforementioned individuals. The nominations should be sent directly to the Secretary General of IAHS and should contain a reasoned argumentation and noted validation of the candidates age;
The Award Committee may not recommend an Award in any one year if none of the papers submitted is of sufficiently high standard.
