← GeographyWhich outcome occurs in a delta plain's distributary channels because natural levees collapse?
A)Increased channel avulsion frequency✓
B)Accelerated floodplain sedimentation rates
C)Decreased tidal prism volume
D)Enhanced salt marsh development
💡 Explanation
Increased avulsion (channel abandonment) occurs when levee collapses cause reduced bank stability and increased sediment influx; therefore the river seeks a steeper, more efficient path, rather than continuing inefficient flow choked by sediment.
