50 Years with Nordic Hydrology/Hydrology Research

The history of Nordic Hydrology/Hydrology Research is described from its initiation in 1970 to its current state in 2021. This includes dramatic changes leading first to an ownership transformation to Nordic Association for Hydrology (NAH) in 1976, and much later, in 2004, to a joint ownership between NAH, British Hydrological Society and IWA Publishing. The development in publication policy during time is covered as well.
