← HistoryWhich outcome frequently appeared when ancient Mesopotamian canals, relying on gravity-fed systems across flat terrain, were constructed using inadequately compacted clay?
A)Erosion and increased sedimentation✓
B)Algal blooms and eutrophication
C)Increased soil salinity downstream
D)Aqueduct structural resonant instability
💡 Explanation
Erosion and increased sedimentation occurred because insufficient compaction caused internal stresses increasing soil displacement via the fluvial erosion mechanism. Therefore canal banks collapsed, filling canals, rather than the system transporting water effectively which maintaining pressure would facilitate.
