As a mesopotamia, which of these would you use to water land

I think the answer is "irrigation" but you didnt give the specifications for the answer

Although Mesopotamia had fertile soil, farming wasn’t easy there. The region received little rain. This meant that the water levels in the Tigris and Euphrates rivers depended on how much rain fell in eastern Asia Minor where the two rivers began. When a great amount of rain fell there, water levels got very high. Flooding destroyed crops, killed livestock, and washed away homes. When water levels were too low, crops dried up. Farmers knew they needed a way to control the rivers’ flow.
