Which outcome commonly occurs along basin edges where sediment-laden rivers abruptly lose confinement?

💡 Explanation

Alluvial fan deposition occurs because a stream's carrying capacity decreases sharply with a sudden reduction in flow velocity outside confined channels. The resulting Sediment Deposition forms the fan rather than continued channel incision due to high competence.
