Description
The international hydraulic development project was first proposed by late Hammarskjold, former UN Secretary-General, as part of a UN program aimed at increasing the national incoms of the developing countries. After a long series of meetings on this proposal, the UNESCO finally resolved in 1961 to undertake the project over 10 years, starting in 1965.

Hydrology is a science that deals with the origin, circulation, distribution of waters on earth, its physical and chemical actions, its interrelations with the biological environments and effects on human activities. The purposes of the international project is intended to expedite the hydrologic research among the nations for effective control and maximum uses of water and to make the survey of hydraulic resources for the benefits of the human community as a whole.

Since our country suffers every year considerable damages in property and human lives by the drought and flood, we have an urgent need for the hydrologic research and therefore, we extended our fuul cooperation to this international project.
