Which process primarily causes oxbow lake sediment infill after river meander cutoff?

💡 Explanation

When a meander loop is cut off forming an oxbow lake, fluvial deposition occurs because the reduced flow velocity within the lake compared to the main channel causes fine sediments carried by the river to settle. Therefore fluvial depostion results, rather than eolian, biogenic, or chemical processes which contribute negligibly to sediment infill over time.
