Which outcome occurs when a meandering stream in a floodplain reaches its graded profile limit?

💡 Explanation

Increased deposition on an alluvial fan occurs because the stream's energy is primarily used for sediment transport; therefore, lateral migration and flooding increase alluvial fan creation down-gradient, rather than accelerated headward erosion or sediment load reduction.
