← GeographyWhich consequence results when prolonged river sediment deposition exceeds compaction?
A)Subsidence near artesian aquifers
B)Increased likelihood of levee breaching✓
C)Eutrophication amplified within river deltas
D)Erosion intensified along bedrock channels
💡 Explanation
Excessive unchecked sediment deposition leads to increased pore water pressure inside the emergent levees. This reduces the shear strength through effective stress reduction, therefore levee failure becomes more likely rather than channel erosion.
