Which outcome enhances stream meandering on shallow gradients?

💡 Explanation

Increased overland flow washes soil away because vegetation's root structures, which provide bank reinforcement, weaken; this positive feedback accelerates the erosion, leading to increased meandering rather than stabilized banks by sediment deposition because of overloading capacity.
