← GeographyWhich outcome is most probable when rapid glacial meltwater introduces saturated alluvial sediment?
A)Decreased channel sinuosity downstream.
B)Increased likelihood of river avulsion.✓
C)Formation of stacked paleosol sequences.
D)Enhanced long-term sediment storage
💡 Explanation
When glacial meltwater overwhelms existing fluvial systems, the additional alluvial load will cause river avulsion because the channel's capacity is exceeded, therefore causing a new, typically steeper, course, rather than gradual meander changes or soil formation.
