Which outcome increases when glacial meltwater overcharges proglacial alluvial fans?

💡 Explanation

Increased meltwater enhances sediment transport causing increased downstream sediment aggradation, because the stream's capacity exceeds the original channel; therefore aggradation occurs, rather than stabilization or biodiversity growth further upslope or downstream relating to normal channel behavior.
