Near river deltas, which floodplain change results from excessive sediment deposition within a meander bend?

💡 Explanation

Increased sediment deposition accelerates meander cutoff due to avulsion, therefore Oxbow lake formation becomes increasingly likely because the river prefers the steeper, more direct path rather than the original meander. Lateral erosion would dominate without such deposition.

• Which effect characterizes stream morphology along an active transform fault boundary?
• Which depositional outcome occurs where a deeply entrenched river emerges onto a broad alluvial plain?
• Which feedback occurs as formerly vegetated surfaces are converted to loess?
• Which outcome commonly follows rapid sediment deposition into a glacial lake?
• Which increased risk results as sinkhole density increases?
• Which mechanism causes patterned ground formation from solifluction processes in periglacial regions?
