Which consequence results when rapid deposition overwhelms alluvial fan equilibrium?

💡 Explanation

River avulsion occurs because increased sediment load promotes channel instability requiring frequent, large-scale shifts termed river channel 'avulsion.' Alluvial buildup forces the river to seek a steeper path, therefore a new flow, rather than increased weathering which is slow.
