From February to April 2006 many rivers across Europe, especially the Elbe and Danube, swelled due to heavy rain and melting snow and rose to record levels.
High Danube levels caused significant flooding in parts of Serbia, Bulgaria and Romania, with damage to property and infrastructure in localities near the shores of the river.
The effects of high water across Southeastern Europe were blamed on the poor levee systems in the affected countries.
[2] Romanian officials ordered the controlled flooding of thousands of hectares of unused agricultural spaces to prevent further damage in cities across Romania.
On April 16, in the localities of Rast and Negoi, Dolj County, more than 800 residents were evacuated, as a dam collapsed due to the rising waters of the Danube.
[3] In the port city of Călărași, a recently opened hotel was flooded on Monday, April 17, causing significant damage to the building and leading to the evacuation of tens of tourists.
"[3] However, by April 28, after several weeks of pressure, key levées along the Danube began collapsing in the counties of Dolj, Călărași, Constanța, Tulcea and Galați.
In Germany, the medieval town of Hitzacker had water levels of 7.63 meters, destroying many buildings and causing considerable damage to other private property.
The German federal state of Saxony and the Czech Republic were not as affected, because in the four years after the record floodings of 2002, the two partners built a stronger levee system along the Elbe.
Many dikes and levees breached because of a poor construction by local and national officials and of an unusual long and hard winter in Central Europe.
