FRIEND-Water (Flow Regimes From International Experimental and Network Data) is an international network of experts that aims to contribute to new understandings of hydrology to better understand the influence of climate, river basins and human activities on the spatial and temporal distribution of water.

As a flagship initiative of UNESCO’s Intergovernmental Hydrological Programme (IHP), FRIEND-Water aims to encourage and strengthen transdisciplinary networks to facilitate: 1) scientific cooperation and capacity building, 2) development of analytical tools and 3) data sharing across national boundaries.

FRIEND-Water consists of over 162 participating countries in 6 regional groups to foster and strengthen international scientific cooperation.

• EURO-FRIEND (Europe)
• MED-FRIEND (Mediterranean Basin)
