Following extreme floodplain sediment deposition, which hydrologic effect encourages oxbow formation?

💡 Explanation

Differential sediment deposition induces channel sinuosity changes, increasing erosion along the outer of the bend of a river and reduced flow on the inner bend, encouraging meander cut-off and oxbow lake formation, because of localized differences in flow dynamics; therefore, the answer is sediments, rather than changes in flow velocity which are more uniform in effect.

• Which wind pattern emerges near mountainous coasts due to uneven heating?
• Which hazard increases when upstream levee construction alters river sediment deposition patterns?
• Which flow behavior occurs in fjord estuaries when freshwater runoff creates a less dense surface layer during winter?
• Which risk predominantly accelerates when coastal kelp forest degrades?
• Which outcome reduces fisheries' productivity when coastal upwelling weakens?
• Which atmospheric effect is amplified when deforestation reduces evapotranspiration in tropical rainforests?
