← GeographyWhich process accelerates the lateral migration of a river's meander across an alluvial plain landscape?
A)Reduction of river sediment load
B)Alternating bank erosion and deposition✓
C)Increased riparian vegetation density
D)Decreased channel sinuosity
💡 Explanation
When alternating flows occur along a meander bend, differential pressure occurs because increased force amplifies erosion and deposition, steering the river. Therefore bank erosion paired with deposition on the inside curve causes continued migration, rather than sediment reduction, increased vegetation or reduced sinuosity which stablize in place the meander.
