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: -The floods brought silt, which made the soil fertile. The silt from the floods contained nutrients and minerals that helped crops to thrive. Controlling the Tigris and Euphrates Rivers was very important. Floods often washed away farms and destroyed mud-brick villages.
Detailed explanation-3: -The farmers who moved to Sumer faced many challenges. One of the biggest problems was the uncontrolled water supply. During the spring, rain and melted snow from the mountains flowed into the Tigris and Euphrates Rivers, causing them to flood across the plains.
Detailed explanation-4: -Sumerians built up the levees by making foundations of reeds impregnated with bitumen, sun-baked surface seepage of crude oil common in the region. Baked mud bricks, also bonded with bitumen, were placed on top of the foundations.
