Which outcome occurs when prolonged floodplain sedimentation exceeds levee accretion rates in fluvial systems?

💡 Explanation

When floodplain sedimentation outpaces levee accretion, differential compaction occurs because the floodplain area becomes higher relative to the channel, eventually inverting their relative elevations. Therefore, inverted river topography results, rather than decreased sinuosity, aquifer depletion, or sediment trapping, which are driven by different geomorphic or hydrological forcings.
