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 outcome diminishes dune migration rate when vegetation emerges?
• Which risk increases when increased glacial erosion coincides with intense wind deflation?
• Which outcome occurs when tectonic subduction halts beneath Tibet?
• Which outcome occurs when increased sediment transport rates overwhelm stabilization efforts?
• Which outcome occurs when glacial melt rate exceeds outflow?
• Which topographic outcome becomes pronounced after glacial retreat around cirques?
