Which outcome occurs when sediment supply exceeds stream transport capacity near a mountain front, promoting widespread aggradation?

💡 Explanation

Braided streams form because excessive sediment causes deposition exceeding the stream's waste-transport ability, leading to channel splitting due to aggradation. Therefore, braided streams rather than channel incision occur, because other stream adjustments are limited by the high load.
