Which effect occurs when river discharge decreases downstream near an oxbow?

💡 Explanation

Channel abandonment occurs, because reduced flow lacks energy to carry sediment via sediment deposition, therefore closing the meander neck; rather than erosion which carves passages or suspension which carries material. The decreased water flow is key!
