AP FRIEND was launch in 1997, is a regional component of FRIEND (Flow Regimes from International and Ex- perimental Network Data) a global crosscutting IHP project aimed at advancing technical knowledge and research in the field of hydrology.
It is coordinated by the IHP Regional Steering Committee for Southeast Asia and the Pacific, with financial support provided by UNESCO regular budget and by a Trust Fund to UNESCO from Ministry of Education, Culture, Sports, Science and Technology (MEXT) Japanese Government and UNESCO Jakarta.
In its first phase, the project provided a framework within which research was carried out to improve the understanding of hydrological science and water resources management in the region through comparative studies of the similarity and variability of the regional hydrological occurrences and water resource systems. With the great efforts from nearly 200 scientists in 5 working groups, significant achievements have been obtained for the Phase I of the Asean Pacific FRIEND during the past several years and summarized in the Asian Pacific FRIEND Report for Phase I (1997 – 2001), published in 2002 (IHP V – Technical Document in Hydrology No. 9, Regional Steering Committee for Southeast Asia and the Pacific, UNESCO Jakarta Office 2002.). UNESCO Jakarta Office 2002.).
For AP FRIEND Phase II, it was decided that themes such as high flows and low flows (including droughts) should be continued from Phase I to Phase II of the project. In particular, as rainfall is an essential input to high flows, low flow and drought analysis and a priority in many countries, it was proposed on rainfall, specifically in terms of: -
In order to progress with the Phase II plan, each country provided input on availability of data both within between the countries, the source organization and finally the design guidelines/standards band analysis technique used by the same countries.
The activities carried out and result obtained in the initial stage of the Asia Pacific FRIEND Phase II, were presented at the Intensity Frequency Duration 2, Determination Meeting held in the Regional Humid Tropics Hydrology and Water Resources Centre for Southeast Asia and The Pacific (HTC) Kuala Lumpur from 6 and 7 June 2005.
