they made irrigation systems and the rivers flooded so that helped
The river system of Southwest Asia, having the Tigris and Euphrates rivers, which have their sources within 50 miles of each other in eastern Turkey and travel southeast through northern Syria and Iraq to the head of the Persian Gulf. The lower part of the region that they define, known as Mesopotamia, was one of the cradles of civilization. The total length of the Euphrates is about 1,740 miles. The Tigris is about 1,180 miles in length.
The Euphrates River is one of the most important rivers in the world. Along with the Tigris, it provided much of the water that supported the development of ancient Mesopotamian culture. The Tigris Euphrates valley was the birthplace of the ancient civilizations of Assyria, Babylonian, and Sumer. In northern Iraq the Euphrates forms the western boundary of the area known as Al Jazirah. To the southeast the alluvial lands between the two rivers was the site of the glorious Babylonian civilizations of ancient times. The Euphrates is important solely for its water supply. The river is the source of political tension, as Turkey, Syria and Iraq all compete for the use of its waters for irrigation and the generation of hydroelectric power. For centuries the river formed the east limit of Roman control. During the supremacy of the Eastern Roman Empire, numerous towns and centers of art and literature flourished along its bank. Much historical data has been yielded by archaeological excavations on the banks of the Tigris and the Euphrates.
The rivers are high at the wrong time of year for most crops, so that cultivation by direct inundation generally cannot be practiced. The initiation of massive irrigation projects in Turkey heralds unprecedented change for the Piedmont area of southeastern Anatolia. Historically, the agriculture of this zone, as well as of northern Iraq and Syria, has been entirely dependent on rainfall. Some minor irrigation by means of mechanical lifts long has been practiced in northern Syria, where vines, olives, tobacco, fruits, and grains have been the mainstays. In Iraq the major field crops are wheat, barley, millet, rice, corn, and sorghum. Sugar beets are grown in the area of Al-ʿAmārah. Date palms have been prized in Mesopotamia since ancient times. Modern palm groves are often interspersed with other fruit trees and vegetable gardens.
