Which outcome occurs when a river's natural levees collapse under extreme hydraulic pressure?

💡 Explanation

Avulsion occurs because levee failure reduces channel confinement, encouraging the river to seek steeper paths through the floodplain via channel switching; therefore, avulsion dominates, rather than continued flow through the old channel which is now blocked.

• Which consequence results when soil experiences increased rates of bioturbation?

• Which consequence results when increased bioturbation affects clay soils?
• Which outcome occurs when islands interrupt prevailing wave patterns?
• Which risk is intensified when hurricane intensity alters the longshore currents parallel to a barrier island?
