Where did the water that was used to irrigate southern Mesopotamia come from? Explain who made use of the water and how the water made the land fertile.

the Tigurs and Ethrups rivers

Explanation:

The water used in the irrigation systems of southern Mesopotamia came from both the Tigris and Euphrates Rivers. Irrigation ditches and canals were used to transport the water to the agricultural areas. The river water was used by several ancient communities, and agreements had to be made to ensure that everyone received their required amount. The water left a layer of silt on the land, and the combination of silt and water made the land more fertile.
