Which outcome was primarily mitigated by the stepped design of Mesopotamian ziggurats managing irrigation flows?

💡 Explanation

When rain fell or irrigation excess occurred, the stepped design acted as a tiered drainage system, preventing erosion because it dispersed runoff energy gradually as gravity moves water downwards. Therefore erosion by runoff was mitigated, rather than saturation, salt damage, or settling from different soil properties which required different soil issues.
