Fresh water resources are diminishing and deteriorating under demographic and climatic pressures. Decision-makers responsible for the sustainable development of freshwater resources need access to accurate and reliable water-related data. WMO supports an integrated, multidisciplinary approach to managing water resources.
WMO promotes water resource assessments by National Hydrological Services who, in turn, provide the forecasts needed to plan water storage for domestic requirements, agricultural activities, hydroelectric power generation and urban development.
The WMO World Hydrological Cycle Observing System (WHYCOS) assists National Hydrological Services in establishing and maintaining systems for acquiring and disseminating accurate and timely water-related information essential for formulating integrated water resources management strategies. Equipped with better hydrologic information, assessments and forecasts, Members are able to independently assess their water resources and respond to the threat of floods and drought.
The Hydrology and Water Resources Programme (HWRP) promotes water-resource assessments and supports National Hydrological Services, River Basin Authorities and other institutions responsible for water management in a wide range of activities. Its aims is to improve effective use of hydrology in sustainable development to reduce the risk and impacts of water-related disasters, such as floods or droughts, and to support effective environmental management at all levels. The Quality Management Framework – Hydrology provides strategy, advice, guidance and tools for National Hydrological Services to attain quality, efficiency and effectiveness in their functioning.
