Detailed explanation-1: -28 In Mesopotamia, the Euphrates and Tigris and their tributaries formed the main sources for irrigation water, which was brought to the fields via a head gate structure, a hierarchy of open surface gravity canals (main and distribution canals) and water-control structures (e.g., regulators, flow dividers, gates).
Detailed explanation-2: -The first few settlements of Kish, Lagash, Ur, Umma, and Uruk established a foothold along the two rivers and benefited from a single irrigation system that supplied their settlements with adequate water flow.
Detailed explanation-3: -To control the water supply, Sumerians built a complex irrigation system. The system crossed village boundaries, so the Sumerians had to cooperate with one another. This led them to live in larger communities-the first cities.
