← HistoryWhich outcome occurs when the water level in a canal lock drops too rapidly during ship passage?
A)The ship grounds due to increased drag
B)The lock gates buckle from pressure
C)The ship lists due to Bernoulli effect
D)The mooring lines snap from surge forces✓
💡 Explanation
When water level drops too rapidly, a surge force develops due to displaced water momentum within the lock chamber because water movement is constrained, overstressing mooring lines. Therefore lines snap, rather than grounding, gate buckling, or listing, which require separate hydrodynamic instability conditions.
