What is the primary characteristic of a meandering channel?

• A. Remaining stagnant
• B. Transporting load in suspension while moving in sweeping bends
• C. Flowing straight without curves
• D. Depositing sediment in the center

Answer: (B)

A meandering channel is characterized primarily by its sweeping bends or curves, which significantly influence the flow dynamics and sediment transport within the channel. As water flows through these bends, it creates a complex flow pattern that allows for the transport of sediment, primarily in suspension. The lateral movement of water around curves contributes to erosion on the outer banks, while deposition occurs on the inner banks, shaping the channel's features over time. The characteristics of flow in meandering channels differ from those in straight channels, where options suggesting straight flow or stagnant conditions would not apply. Also, while sediment deposition does occur, it is not exclusively in the center; rather, it often happens on the inner edges of the bends, highlighting the dynamic nature of meandering channels in contrast to more static or linear channel forms.
