Which geomorphic consequence results when a river's sinuosity increases significantly near an oxbow lake formation?

💡 Explanation

When a river's sinuosity (curve length) increases nearing oxbow formation, the stream power per unit length decreases because energy is dissipated over a longer path, this leads to accelerated deposition especially during floods. Therefore Sediment accumulation speeds up oxbow lake filling, rather than valley incision or bank stability which results from fundamentally different hydrodynamics.
