Which geological phenomenon arises when river levees are breached?

💡 Explanation

A levee breach causes a crevasse splay because sediment-laden water rapidly flows through the break, depositing sediment on the floodplain; therefore, crevasse splays are created because of the failure rather than stable levee/channel conditions.
