Which outcome arises when glacial meltwater outflow diminishes downstream within an alluvial fan?

💡 Explanation

Less meltwater reduces the stream's capacity; reduced stream power causes reduced capacity for erosion and sediment transport via hydraulic action. Therefore, distal stream incision decreases rather than increasing, because lowered flow cannot sustain original channel depths.
