Which process contributes to the formation of braided streams on alluvial fans during arid climate flash floods?

💡 Explanation

When overland flow occurs on an alluvial fan, aggradation occurs due to a decrease in stream gradient, exceeding the capacity of the moving water to transport sediment load, creating multiple, unstable channels. Therefore sediment deposition exceeds transport capacity, rather than other processes associated with incision or consistent flow.
