The Association shall be known as the INTERNATIONAL ASSOCIATION OF GEOMORPHOLOGISTS or, in languages other than English by a direct translation. The official abbreviation will be the IAG. The working languages of the IAG shall be English and French.


There are two founding principles to govern the style of the conduct of the affairs of the Association:

the IAG shall be a non-governmental, non-political, non-profit, scientific institution at all times free of racial, gender or national prejudice;

the IAG shall be maintained in as informal a style as possible in keeping with the relaxed international and individual friendships established at the First International Conference on Geomorphology, Manchester 1985.


The objectives of the IAG shall be:

a) to develop geomorphology through international co-operation;

b) to promote the study and development of geomorphology in all aspects;

c) to foster the dissemination of knowledge of geomorphology.


The IAG will accomplish these objectives by:

a) holding an International Conference on Geomorphology at least every four years;

b) holding Executive Committee and open meetings at the time of the International Conference and, if required, at suitable times and locations between conferences;

c) encouraging the establishment of both regional and specialty groups, the organisation of meetings, research and field programs and publications on geomorphology;

d) co-operating with national and international organisations whose aims are complementary to those of the IAG;

e) exchanging information through its National Scientific Members, newsletters, publications or other suitable mechanisms;

f) encouraging the participation of geomorphologists in the work of relevant international organisations on the basis of equal opportunities.


The IAG recognises the International Council for Science (ICSU) as being the co-ordinating and representative body for the international organisation of science and is affiliated to it through the International Geographical Union (IGU) and the International Union of Geological Sciences (IUGS).


Membership of the IAG shall normally be by countries.

Normally membership of the association, which carries full voting rights, shall be through National Scientific Members. There shall be only one National Scientific Member per country. Countries wishing to join the IAG must submit to the Secretary documentation showing the existence of a bona fide National Scientific Member, its mailing address and the names of its officers.

In countries where no National Scientific Member exists an individual may take part in all activities of the IAG but will not have voting rights.


A National Scientific Member shall be a Scientific Academy, Research Council, Scientific Institution or association of such institutions. Institutions effectively representing the range of scientific activities in a definite territory may be accepted as National Scientific Members provided they can be listed under a name that will avoid any misunderstanding about the territory represented. Each National Scientific Member shall have only one vote.

A National Scientific Member shall at all times keep the Secretary of the IAG informed about its address, the names of its officers and its voting representative.

National Scientific Members may adhere to the IAG in one of the categories, determined by the number of geomorphologists and the economic state of its nation and specified in the bylaws. Each National Scientific Member shall pay a subscription proper to its category. Continuous record of payment of membership fees is necessary to acquire full voting rights.


The IAG shall be served by an Executive Committee consisting of the elected and co-opted members.

The elected members are:

a) a President;

b) three Vice-Presidents;

c) a Secretary;

d) a Treasurer;

e) a Publications Officer.

Nominees for presidency shall have served as elected members of the Executive Committee in the term immediately preceding their nomination.

Elected members shall serve a maximum of four years in any post. All elected members are to be from different countries. The Executive Committee may co-opt members at anytime necessary to maintain the aims of the IAG.


The Executive Committee shall be responsible to the Council of the IAG. The Council shall consist of the voting representative of each National Scientific Member (or their authorised deputies) plus the members of the IAG Executive Committee. The Council shall be presided over by the President of the IAG or, in case of the President’s incapacity to attend, by one of the Vice-Presidents designated by the Executive Committee. In the event of an equal decision of votes, the President or acting President shall cast the deciding vote.

The Council shall meet every four years during the International Conference on Geomorphology. An extraordinary session can be called during an IAG Regional Conference or if requested by a majority of the National Scientific Members. The Council may make decisions by postal communication on questions put to it through the Secretary with the approval of the President.

The Council may set up standing and ad hoc committees and working parties with whatever names, powers and terms of reference it may decide.

The Council shall determine, with the advice of the Secretary, the annual subscription fee to the Association. The Council shall approve the budget and authorise disbursement of funds.


At each International Conference on Geomorphology (ICG) two General Assemblies shall be held. General Assembly is open to all those who have registered to the ICG. The purpose of General Assembly is to further communication between the Executive Committee and individual geomorphologists.


The IAG may confer Honorary Fellowship upon individuals who have served the Association or the discipline of geomorphology with particular distinction. Honorary Fellowship shall be regarded as the highest honour that the IAG can bestow.


Sustaining membership shall be available upon invitation, to individuals and institutions sympathetic to the purposes of the IAG and willing to be identified without vote with its programmes, specific or general.


An International Conference on Geomorphology shall be held every fourth year in a country to be decided upon by the Council. The organisation and financial arrangements of an International Conference are the responsibility of the National Scientific Member of the host country. The only rule for the International Conference is that it shall be organised in such a way that a relaxed and informal ‘geomorphological’ style be adopted consistent with maximum productivity.


This constitution shall come into force in one of two ways, either at the close of the session at which it receives the approval of at least two-thirds of the Council present or by a postal vote approved by two-thirds of those returning ballots, provided that half of the members take part in the voting.


Amendments to the Constitution may be proposed by the Executive Committee or by a National Scientific Member. Such amendments shall be submitted in writing to the Secretary early enough to have the proposal submitted to all National Scientific Members at least one year prior to the Council Meetings at which the amendment is to be placed on the Agenda.

Adoption of an amendment to the Constitution will require an affirmative vote of at least two thirds of the Council present or by postal vote approved by two thirds of those returning ballots, provided that half of the members take part in the voting.



i) A quorum for a Council meeting shall be a simple majority (more than 50 %) of the National Scientific Members.

ii) Any member country that will not be present for a vote may submit its views and vote in advance by mail. In this case that member country will be regarded as being present for the purposes of the quorum for the vote.
