1. THE OBJECTIVES OF THE ASSOCIATION

1.1. To promote the study of Hydrology as an aspect of the earth sciences and of water resources;
- to study the hydrological cycle on the Earth and the waters of the continents; the surface and groundwaters, snow and ice, including their physical, chemical and biological processes, their relation to climate and to other physical and geographical factors as well as the interrelations between them;
- to study erosion and sedimentation and their relation to the hydrological cycle;
- to examine the hydrological aspects of the use and management of water resources and their change under the influence of man's activities;
- to provide a firm scientific basis for the optimal utilization of water resources systems, including the transfer of knowledge on planning, engineering, management and economic aspects of applied hydrology.
1.2. To provide for discussion, comparison, and publication of research results.
1.3. To initiate, facilitate, and coordinate research into, and investigation of, those hydrological problems which require international cooperation.

The Association shall comprise: the Plenary Session, the Bureau of the Association, the Scientific Commissions, the Panels and Working Groups and the International Association of Hydrological Sciences Limited. The Association shall maintain contact with the several adhering countries through their National Representatives or National Committees (often subcommittees or sections of the IUGG National Committees) and Regional Committees.

Scientific Commissions: Units of the Association having defined scientific responsibilities in specific hydrological fields or subjects. Divisions are corresponding units of the Scientific Commissions.

Panels or Working Groups: Ad hoc units to report on specific problems, either scientific or administrative.

National Committees: National Committees of IAHS are administrative bodies for maintaining contacts with the Association. They may include representatives to the Scientific Commissions of IAHS.
