Which consequence results when rapid sedimentary deposition occurs on an alluvial plain during seasonal flooding?

💡 Explanation

Levee breaching increases catastrophic flooding because rapid deposition raises the riverbed, decreasing its capacity; this positive feedback loop exacerbates overbank flow via bank instability, a fluvial erosion mechanism. Therefore, levees are more prone to structural failure, rather than enhanced stability after floods because the water force is heightened.
