Which outcome often occurred within a pre-Columbian aqueduct system when maintenance declined amid expanding maize cultivation?

💡 Explanation

Expanding cultivation increased sediment runoff; therefore, enhanced canal sedimentation rates reduced capacity because the sedimentation mechanism plugged channels, rather than pressure increases or water loss given available topology.
