DANUBE RIVER : SLOVAKIA : HUNGARY

DANUBE RIVER : SLOVAKIA : HUNGARY

The Danube River is the second longest river in all of Europe, after the Volga, and is the longest river in the European Union.

Once a long-standing frontier of the Roman Empire, today it flows through 10 countries. Originating in Germany, the Danube flows southeast for 2,860 km (1,780 mi), passing through or touching the border of Austria, Slovakia & Hungary (pictured), Croatia, Serbia, Romania, Bulgaria, Moldova and Ukraine before emptying into the Black Sea.

Visible in this overlay, created from satellite imagery using ESRI ArcGIS & Adobe Creative Cloud integrations, the Gabčíkovo Dam (bottom right) was part of a greater project between Slovakia and Hungary.

The Gabčíkovo-Nagymaros Dams was a joint Hungarian–Czechoslovak project agreed upon in 1977 to eliminate regular flooding (like the disastrous ones of 1954 and 1965) and provide a clean source of electric power. They would also allow year-long navigability of the river and serve as a part of the Rhine-Main-Danube Canal system of inland navigation.

Only a part of the project was completed in Slovakia, under the name Gabčíkovo Dam, because Hungary first suspended then tried to terminate the project due to environmental and economic concerns.

North-West of this scene lies Bratislava, the capital of Slovakia and a gateway for migrants seeking asylum in bordering Austria and beyond.
