Which risk increases when channelized river flow shifts course rapidly?

💡 Explanation

Accelerated delta lobe avulsion occurs because sediment supply and deposition via longshore drift destabilizes the existing channel’s bathymetry; therefore, a new channel will form rather than maintaining the original flow path because equilibrium will favor efficiency.
