The Euphrates has dried up on its own in the past. The ancient Sumerians had an irrigation system in 3000 BC that allowed them to develop civilization. They were absorbed into the empire of the Akkadians about 2300 BC, but the Akkadians had various problems, and a prolonged drought finished them off. The irrigation failed and the nomadic Amorites had the advantage over the sedentary farmers.
