Which outcome occurs when sediment input exceeds transport capacity in a fluvial system depositing material in radial pattern?

💡 Explanation

Alluvial fan formation occurs because sediment deposition increases as the stream's carrying capacity reduces, resulting in radial accumulation due to decreased flow energy; therefore, a fan develops, rather than channel incision or oxbow formation relating to lateral channel migration.
