Which effect arises when the Roman aqueduct's specus experiences significant scaling?

💡 Explanation

Scaling narrows the channel, causing a reduction in the cross-sectional area for flow, because it increases hydraulic resistance; therefore the flow rate decreases downstream, rather than experiencing elevated oxygen as with turbulent systems.
