Which risk increases disproportionately with heightened sediment loads delivered to an alluvial fan by sudden, intense rainfall?

💡 Explanation

Increased sediment delivery to an existing alluvial fan encourages stream avulsion which enables new flow paths, because flow becomes unstable due to altered slope angles. Therefore, channels shift more frequently rather than evaporation, groundwater, or oxygen variations which occur independently.
