Which outcome occurs when a river's sediment load dramatically increases entering a floodplain lake?

💡 Explanation

Progressive infilling with sediment creates ephemeral lakebeds because increased sediment deposition by the river overwhelms the lake's capacity; this leads to the 'sedimentation mechanism'. This effect generates shallower systems rather than enhanced eutrophication from nutrient overloading.
