Hydrology has been an indispensable essential component since establishment of ESCAP/WMO Typhoon Committee in 1968. It has been repeatedly recognized as most active component in the Committee who has integrated conducted successfully a number of cooperation projects and integrated actions among Members. At the 33rd Session in 2000, the Committee decided to establish a Working Group for Hydrological Component to be responsible for the planning and implementation of a comprehensive review of the hydrological component and disaster preparedness and prevention, and become the first working group of three components of meteorology, hydrology and disaster risk reduction (DRR).

The Committee at its 45th Session in 2013 re-established the Working Group on Hydrology (WGH) with Terms of Reference (TOR) and operational modalities in order to coordinate efforts on the implementation of various activities under the Hydrological Component with the aim to better support the socio-economic development process in the Typhoon Committee Area and to help accomplish the hydrological related goals and objectives described in the Strategic Plan of the Committee.
