USA HISTORY

Detailed explanation-1: -The farmers in Sumer created levees to hold back the floods from their fields and cut canals to channel river water to the fields. The use of levees and canals is called irrigation, another Sumerian invention.

Detailed explanation-2: -To irrigate is to water crops by bringing in water from pipes, canals, sprinklers, or other man-made means, rather than relying on rainfall alone.

Detailed explanation-3: -So, Sumerian farmers began to create irrigation systems to provide water for their fields. They built earth walls, called levees, along the sides of the river to prevent flooding. When the land was dry, they poked holes in the levees. The water flowed through the holes and into the thirsty fields.

Detailed explanation-4: -The civilization of Ancient Mesopotamia grew up along the banks of two great rivers, the Euphrates and the Tigris. In the midst of a vast desert, the peoples of Mesopotamia relied upon these rivers to provide drinking water, agricultural irrigation, and major transportation routes.
