History

Which outcome occurred when Mesopotamian canals experienced excessive silt accumulation near off-take points?

A)Reduced water flow downstream
B)Collapse of canal sidewalls
C)Increased risk of salinization
D)Growth of invasive aquatic weeds

💡 Explanation

When silt accumulated excessively near off-take points, sedimentation occurred because the flow velocity decreased, causing suspended particles to settle and block the canal, especially downstream. Therefore reduced water flow results, rather than collapse, salinization, or weed growth, which depend on different failure processes.
