← HistoryWhich physical consequence occurs with increased aqueduct siphon head pressure?
A)Intensified hydraulic fracturing erosion✓
B)Diminished mineral sediment accumulation
C)Enhanced biogenic biofilm formation
D)Reduced hydrostatic pressure variability
💡 Explanation
Increased siphon head leads to higher internal water pressure. This intensifies hydraulic fracturing erosion because, the increased pressure weakens the concrete over time. Therefore structural integrity declines, rather than sediment or biofilm formation being enhanced.
