Which process limits levee growth due to sediment discontinuities?

💡 Explanation

Aggradation occurs because crevasses interrupt levee formation with localized fine sediment deposits; therefore, vertical build-up varies rather than producing uniform strengthening, hindering long-term protection compared to continuous deposition.
