Which outcome occurs when a Roman aqueduct siphon's discharge elevation is significantly higher than its intake elevation?

💡 Explanation

When discharge elevation exceeds intake, the hydrostatic pressure within the inverted siphon increases greatly to overcome the gravitational head, creating extreme circumferential stress because of the water column's weight. Therefore structural failure is more likely, rather than rate increase, sediment issues, or collapse, which are related to other hydraulic conditions.
