Which risk increases because of reduced flow velocity in an oxbow lake compared to the main river channel?

💡 Explanation

When velocity decreases, thermal stratification increases because reduced mixing allows warmer surface layers to stay separate from cooler, denser, bottom layers, inhibiting convection. These layers resist mixing, because there is less kinetic energy to initiate eddy formation so decreased density increases, rather than the stream bank erosion, oxygen solubility, and sediment transport because those factors depend higher amounts of kinetic energy.
