World Hydrological Cycle Observing System Guidelines
WHYCOS is a global concept, comprising a number of independent regional or basin-wide Hydrological Cycle Observing System (HYCOS) components. At the local level within a country, HYCOS brings together various agencies to work on delivering enhanced data and information products, such as the production and delivery of flood forecasts and warnings. An important complementary activity is the building of closer ties to communities and groups whose primary mandate benefits from access to the enhanced data, products and services, thereby achieving increased positive societal impacts. This contributes to increasing the capacities of institutions and communities to work more closely together. In the light of experiences gained from the implementation of regional HYCOS projects since the inception of WHYCOS, the WHYCOS International Advisory Group (WIAG) was set up to oversee its coordination, provide policy guidance and advise on its future development. It has called for a common, yet flexible, approach to the development and implementation of HYCOS components. The Guidelines presented herein are therefore aimed at ensuring that each project remains consistent with the WHYCOS vision, objectives and principles, while responding to local and regional needs, realities and changing situations.
