Detailed explanation-1: -Answer and Explanation: The villages of Sumer worked together to clean the canals. The Sumerians farmed and irrigated their lands; thus, the irrigation system carried water from the river to the fields through their towns. Therefore, the system required constant maintenance by cleaning the silt that clogged in them.
Detailed explanation-2: -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-3: -Food shortages had forced settlers in Mesopotamia to move from the foothills down to the river valley. There, farmers faced the problem of having either too much water or too little. To control the water supply, Sumerians built a complex irrigation system.
Detailed explanation-4: -Mesopotamians created irrigation systems to protect against damage from too much or too little water and to ensure a stable supply of water for crops and livestock.
