The Sava River in South-East Europe is the largest tributary of the Danube. Its catchment covers five countries, and it is home to over 8 million people. The region is vulnerable to flooding, however - floods in 2014 caused the deaths of 79 people and an estimated €3.9 billion of damage in Croatia, Serbia and Bosnia and Herzegovina, forcing thousands more to leave their homes.
Flood forecasting, as well as environmental protection, transportation and energy production, requires those who manage the river to coordinate their hydrological monitoring and share the resulting data. Efficient, effective collaboration between the countries that share the Sava River Basin, Bosnia and Herzegovina, Croatia, Serbia, Slovenia and Montenegro, is therefore crucial for reducing flood risk and implementing effective water management strategies.
