Which flow outcome results when debris deposition overwhelms channel capacity at steep mountain exits, forming alluvial fans?

💡 Explanation

Braided streams develop due to high sediment load because the increased flow widens and divides around sediment bars; the process is aggradation, rather than enhanced sediment transport farther downstream, therefore braided channel development occurs rather than downstream changes.
