2. Hydrological Institutions in Turkey Hydrological organisations in Turkey are the General Directorates of the State Hydraulic Works, Electrical Power Resources Survey and Development Administration, State Meteorological Affairs, and the universities namely Middle East Technical University and Hacettepe University, Gazi University, Istanbul Technical University, 9 Eylul University, all who are major contributing members of the Turkish hydrological community. General Directorate of State Hydraulic Works (DSI), being the main organisation widely representing the hydrological community in Turkey, is actively engaged in co-ordinating the hydrological organisations in the Country. DSI has an official mission for functioning of coordination, as a focal point for various international hydrologic programs, covering the provision of advice to the management on all related research, training, educational and practical matters in hydrology and giving the increased responsibility to DSI having more ability in shaping national water resources policies.

3. The Office of International Hydrological Affairs In order for institutionally harmonizing of the international hydrological activities, t he Office of International Hydrological Affairs has been established under the auspices of the Investigation and Planning Department, DSI, to carry on the international hydrological relations. The Unit is serving as a focal point for various international hydrologic projects or programs, which are leading issues for the improvement of operational hydrologic works and scientific studies in the Country, such as International Association of Hydrological Sciences (IAHS), UNESCO International Hydrological Program (IHP), WMO Operational Hydrology Program including Commission of Hydrology (CHy), Hydrological Advisory and Hydrological Operational Multipurpose System (HOMS), and also other international hydrological initiatives.

7. Hydrological Archieve All available hydrological documents, including the publications of UNESCO, WMO and IAHS are stored in an archive, and timely introduced to the members of the hydrological community, using the facility of weekly e- bulletin and the physical environment of a library. Furthermore, it is the function of the Office to offer a forum for the hydrological sciences, thus making the national and international aspects of the hydrological community accessible for the mutual benefit of every members.

8. All information related to the hydrology is distributed to the members of the hydrological community using the facility of "hydrology e-group (hidroloji@yahoogroups.com) in which the members of the Turkish National Hydrological Commission (TNHC) is dominated.hidroloji@yahoogroups.com Presently, the Hydrology e-Group has more than 400 members who supply active participation to the studies. News related to the hydrological issues which are considered in the framework of international hydrological activities and news from study groups (sub-commissions) inside TNHC are issued in a newsletter published on a weekly base. The e- Group serves also as a forum environment, which has been found quite effective in informing and in discussing the hydrological issues of the agenda. Hydrology e-Group

9. UNESCO International Hydrological Program (IHP) History The IHP has existed since 1975, following on the International Hydrological Decade, and is implemented in six-year phases. Objectives The aim of the IHP is to encourage hydrological research in order to create a scientific foundation for sustainable water resources management. Realisation The contributions to IHP are supervised by the national committees of the member countries. A secretariat at UNESCO in Paris coordinates and supports the programme activities.

11. WMO Hydrology and Water Resources Programme (HWRP) Issues regarding water are dealt with at different levels by various national and international organisations. Within the organisation of the United Nations (UN) only UNESCO and WMO have wide-ranging water programmes. As a member of the specialised agencies of the United Nations, UNESCO and WMO, Turkey is committed to contributing actively to their hydrological programmes. These are known as the International Hydrological Programme (IHP) of UNESCO and the Hydrology and Water Resources Programme (HWRP) of WMO.

12. International Association of Hydrological Sciences (IAHS) The International Association of Hydrological Sciences (IAHS) is the oldest and foremost international nongovernmental organization that deals with hydrology and water resources. IAHS is one of the seven associations that form the International Union of Geodesy and Geophysics (IUGG). The members of the Association are primarily the representative countries who vote on IAHS policy. There are also individual members.

13. The objectives of IAHS 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 managementof water resources and their change under the influence of mans 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; to provide for discussion, comparison, and publication of research results; to initiate, facilitate, and coordinate research into, and investigation of, those hydrological problems that require international cooperation.
