Which outcome occurs when rapid glacial melt floods an alluvial plain?

💡 Explanation

Increased alluvial sediment and water volume causes increased lateral channel instability, leading to avulsions because the stream seeks a steeper, more direct path across the floodplain. Therefore, avulsions become rapid and frequent following dramatic hydrological changes, rather than predictable migration.
