Which process causes the formation of distributary channels on an alluvial fan?

💡 Explanation

When sediment load increases beyond the transport capacity of the stream on a decreasing slope, aggradation occurs because excess sediment deposition raises the streambed, leading to channel divergence and distributary formation. Therefore increased sediment load and decreased flow lead to distributaries, rather than other conditions that would maintain a single channel.
