← GeographyWhich outcome occurs when levees undergo differential consolidation?
A)Increased probability upstream levee breach
B)Formation of crevasse splays nearby✓
C)Decreased floodplain sedimentation rates
D)Stabilization of existing channel migration
💡 Explanation
Crevasse splays form nearest to the differential subsidence because uneven settling causes localized stress concentrations and potential cracking, resulting in localized levee failure and sediment outflow via avulsion, rather than affecting distant levee sections or stabilizing fluvial processes.
