Which outcome usually occurs as sediments deposit within fluvial levee systems?

💡 Explanation

Channel avulsion (sudden abandonment of a river channel) occurs because the levee builds up and reduces the stream’s gradient, therefore the river’s energy dissipates and the flow is shifted, rather than remaining within the original channel.
