Which outcome results when a meandering stream breaches its levee system during high discharge?

💡 Explanation

Avulsion occurs because high discharge overwhelms the stream's capacity, breaching the levee and causing the stream to seek a steeper, more direct path; therefore, a new channel forms rather than continued flow where the levee holds.
