What was two methods used to control annual floods in mesopotamia?

In ancient Mesopotamia, two key methods used to control annual floods were the construction of levees and the development of an extensive irrigation system. Levees, or raised banks, were built along riverbanks to prevent overflow during peak flood seasons. Additionally, the irrigation system allowed for the diversion of river water to agricultural fields, managing both the water supply and mitigating flood risks while ensuring reliable crop production.
