Which outcome resulted when Mesopotamian irrigation canal silt deposition exceeded removal rates?

💡 Explanation

When silt deposition exceeded removal, canals narrowed by sedimentation, reducing water flow and increasing waterlogging; evaporative concentration of salts in the soil then increased because evaporation exceeds sufficient flushing precipitation, resulting in salinization. Therefore land salinization results, rather than improved navigation, reduced potability, or strengthened controls which require different mechanisms.
