WMO-HWRP is the Hydrology and Water Resources Programme of the World Meteorological Organisation. It focuses on the assessment of the quantity and quality of water resources. It provides advice to members on flood management and IWRM. It helps national hydrological services to provide the hydrological data and information required for the sustainable development of their countries. The Commission for Hydrology (CHy) provides guidance for the implementation of the programme. The Royal Netherlands Meteorological Institute (KNMI) is the Dutch representative in the WMO-HWRP.

The Open Panel of Commission for Hydrology Experts (OPACHE) is the reservoir of scientific and technical expertise that the Commission for Hydrology (CHy) uses to fulfil its mission. Activities include participating in specialized hydrologic, hydrometric, and water resources studies; serving on expert advisory teams; contributing to manuals, guidance material, and technical reports; and participating in workshops and expert meetings.

The Netherlands has nominated 6 extra OPACHE experts during the CHy-15. This brings the Dutch OPACHE team to 9 active panel experts.

These Dutch OPACHE members are the Dutch expert input for the HWRP of WMO. The Hydrology and Water Resources Programme (HWRP) is concerned with the assessment of the quantity and quality of water resources, both surface and groundwater, in order to meet the needs of society, to permit mitigation of water-related hazards, and to maintain or enhance the condition of the global environment. It includes standardization of various aspects of hydrological observations and the organized transfer of technologies for enabling Hydrological Services to provide the hydrological data and information required for the sustainable development of their countries. It provides advice to Members on flood management policy and assists them in their effort to adopt Integrated Water Resources Management (IWRM) with an emphasis on practical applications.
