Hydrology Network (GTN-H) Project Overview
The GTN-H is a joint project of GCOS, the World Meteorological Organization (WMO) Hydrology and Water Resources Programme (HWRP) and GTOS. GTN-H constitutes:
- A global hydrological network of networks
- Projects that establish and facilitate access to hydrological networks, data and products
- A building block for integrated global products for climate and water (IGOS Water, GCOS, GEO)
Please find more details on the GTN-H home page

Program Management
For over 65 years, the World Meteorological Organization (WMO) and its predecessor, the International Meteorological Organization, have supported National Hydrological Services, River Basin Authorities and other institutions responsible for water management in a wide range of activities which together form the Hydrology and Water Resources Programme of WMO (HWRP). The GTN-H, a joint initiative of HWRP and GCOS, is working towards meeting the needs of the international science community for hydrological data and products to support global and regional climate and water analyses.
GTN-H aims at providing hydrological information for improved climate and weather prediction, detection and attribution of climate change, impact assessment of climate change, the assessment of freshwater sustainability, and better understanding of the global water cycle.
Data Management
Data are primarily managed by individual countries in the regional networks under the auspices of the HWRP. A dedicated project has been defined with GTN-H aiming at standardized hydrological data management, access, and archiving (see Data Sharing Strategies on the GTN-H home page)
Users
Managing fresh water resources, droughts and floods and inventory data are important variables for
- climate system monitoring and climate change detection,
- hydrological modeling with respect to possible effects of atmospheric warming, and
- providing fundamental information on flood risk assessment, flood plain management, accurate and timely drought prediction and flood forecasting, management of fisheries, wetlands and irrigation.
