A report released earlier this year by the United Nations Environment Protection agency (UNEP) predicts that the river Euphrates could dry up by 2025.
The report indicated that due to global warming, lower rainfall and increased temperatures could cause the river to fail.
This is a step further on from a Japanese survey last year which concluded that the Euphrates could lose 41% of its flow volume due to reduced rainfall.
The UNEP report also named the Tigris and other great rivers as being at risk. The volume of water in the Amazon and the Yangtze is already down by at least 25% and this now seems to be a general trend around the globe.
