Regional Activities in Hydrology
Decisions concerning the implementation of the regional activities are taken by the WMO Regional Associations at their four-yearly meetings. The six Regional Associations of WMO have each established a working group on hydrology (WGH), and a Regional Hydrological Adviser (RHA) represents his/her entire Region and authoritatively represents the regional hydrologic concerns, problems or expectations, particularly as based on regional consultations. At the national level, the Hydrological Adviser (HA) is the ambassador of WMO hydrology.
