A braided stream typically indicates which condition of sediment transport?

• A. Greater channel capacity than load
• B. Low sediment load
• C. Greater load than capacity
• D. Steady, slow flow with little sediment

Answer: (C)

Braided streams form when there is more sediment coming in than the river can move downstream with the available flow. When the load exceeds the channel’s transport capacity, sediment is deposited in the bed, creating mid-channel bars around which the flow splits into multiple, shifting channels. This continual Redistribution of sediment and changing discharge causes the braided pattern to persist, especially where sediment supply is high or flow is highly variable. If the channel had more capacity than load, or if the flow were steady with little sediment, you’d expect a single, stable channel rather than a braided network. A steady, slow flow with little sediment wouldn’t generate the characteristic braided pattern.
