What did Hammurabi do to the water to attack the sumerians?

Hammurabi, the sixth king of Babylon, is known for his military campaigns against the Sumerians and other neighboring city-states. To attack the Sumerians, he strategically diverted rivers and irrigation canals, disrupting their water supply and agricultural production. This tactic weakened their economy and defense, making it easier for Hammurabi's forces to conquer Sumerian territories. His actions exemplified the use of environmental manipulation in warfare during that era.
