Which consequence results when rapid alluvial fan deposition constricts a river?

💡 Explanation

Braided streams appear because rapid deposition narrows the channel, increasing flow divergence via avulsion. Increased stream gradient and sediment load drive rapid sediment shifting, therefore forming unstable interwoven channels, rather than stable single-thread pathways if deposition were more controlled.
