← HistoryWhich consequence results when the aqueduct's pozzolanic concrete lacks sufficient binder?
A)Decreased hydraulic head develops along sections
B)Reduced flow rate lowers water supply✓
C)Increased hydrostatic pressure causes bursts
D)Elevated sedimentation accelerates channel blockage
💡 Explanation
Reduced binder leads to increased porosity because hydraulic resistance increases due to permeation rather than direct structural collapse, therefore the aqueduct experiences a lower flow rate, rather than head loss from friction, bursting from high pressure, or sedimentation problems.
