The lower course of the river Maritsa/Evros, where it forms the border of Greece and Turkey, is very vulnerable to flooding.
For about 4 months every year, the low lands around the river are flooded.
This causes significant economic damage (loss of agricultural production and damage to infrastructure), which is estimated at several hundreds million Euro.

Recent large floods took place in 2006 and 2007.
Several causes have been proposed: more rainfall due to climate change, deforestation in the Bulgarian part of the catchment area, increased land use in the flood plains and difficult communication between the three countries.
