Which outcome is accelerated within deeply incised alluvial valleys?

💡 Explanation

Thalweg migration increases due to focused flow intensification and bank erosion, therefore destabilizing valley walls because downcutting reduces lateral support, rather than encouraging deposition normally associated with lower gradient alluvial spreading of flow.
