Which process dominates when a high sinuosity river forms an oxbow lake during flood season?

💡 Explanation

When a high sinuosity river floods, increased hydraulic forces cause avulsion by rapidly eroding the meander neck, bypassing flow becomes dominant, causing an oxbow lake to form. Therefore, avulsion occurs rather than erosion, aggradation, or weathering primarily caused by steady state hydrodynamic regime.
