Which consequence results when a river's sinuosity reaches peak instability?

💡 Explanation

Runaway meander growth from high channel sinuosity triggers rapid river course changes because neck cutoff, a mechanism forming oxbow lakes, accelerates; therefore, oxbow formation increases rather than stable channel morphology, because sediment equilibrium will shift rapidly.
