Which river morphology is prevented when levees fail?

💡 Explanation

Levee failure will reduce the river's capacity to laterally erode and deposit sediments via crevassing and related mechanisms. This prevents the cutoff and abandonment of a meander bend necessary for oxbow lake formation, because incision is redirected rather than concentrated on bend development; therefore oxbow lake formation, rather than these river patterns is prevented.
