Which outcome occurs downstream when sediment influx exceeds capacity in fluvial systems?

💡 Explanation

An increase in sediment leads to increased aggradation, causing deposition in the form of alluvial fans due to reduced transport capacity. This is channel avulsion caused increased gradient; rather than erosion lessening or levees forming because carrying exceeds capacity.

• Which consequence results when reduced vegetation accelerates topsoil loss?
• Which outcome maximizes infiltration rate when creating crop terraces on an alluvial fan?
• Which sediment sorting process creates distinctive horizontal layering in glacial lake deltas?
• Which outcome results when freeze-thaw weathering weakens rocks?
• Which risk increases when differential pressure forces magma into forming volcanic domes underneath a glacier?
• Which limit maximizes silica-rich lava dome collapse frequency?
