← GeographyWhich topographical outcome occurs when seasonal flooding deposits sediment atop an alluvial fan?
A)Entrenched channels exceeding base level
B)Development of radial drainage patterns
C)Formation of a braided stream network
D)Deposition of levees flanking distributaries✓
💡 Explanation
When seasonal flooding occurs, overbank flow deposition results because sediment-laden waters lose velocity as they spread, creating natural levees bordering distributary channels of an alluvial fan. Therefore, levee formation results, rather than entrenched channels, radial patterns, or braided streams, which arise from different erosional and depositional conditions.
