Which outcome occurs along a river when floodplain sedimentation overtops artificial levees?

💡 Explanation

Crevasse splays form because when floodwaters surmount levees, concentrated flow erodes the levee and deposits sediment, thereby creating new channels spreading onto the floodplain, rather than causing channel erosion or stable terraces formation.
