← HistoryWhich outcome occurs relating to Roman aqueducts when travertine deposition narrows culvert inlets?
A)Flow rate reduction downstream occurs✓
B)Increased purification occurs downstream
C)External pressure load decreases overall
D)Reduced overall structural load exists
💡 Explanation
Reduced channel volume causes a flow rate reduction downstream because reduced cross-sectional area increases fluid resistance, therefore decreasing conveying capacity; rather than purification, pressure, or structural load alterations that are secondary effects induced.
