Which process causes oxbow lake blockage when sediment supply increases within a floodplain system?

💡 Explanation

When sediment supply overwhelms transport capacity, channel aggradation occurs because deposition outpaces erosion, leading to blockage of the oxbow lake's connection to the main channel. Therefore aggradation results in lake isolation, rather than slope, rainfall or vegetation changes causing blockages.
