Which fluvial outcome results as bend sinuosity increases?

💡 Explanation

Oxbow lakes form via channel avulsion; increased sinuosity leads to neck cutoff because hydraulic gradient steepens between meander bends. Therefore, the formation process amplifies, rather than reduced flow velocity, base level changes or divide propagations under those geometric conditions.

• Which outcome is directly amplified when a coastal gyre weakens?
• Which outcome results when coarse sediment deposition overwhelms a drainage network at a mountain range base?
• Which risk escalates as near-surface permafrost thaws in high-latitude coastal regions due to thermokarst processes?
• Which process dominates sediment sorting in a proglacial lake experiencing increased meltwater discharge?
• Which outcome occurs when lahars deposit unconsolidated sediment?
• Which risk increases because excessive removal of vegetation occurs in permafrost regions?
