Which mechanism causes a braided stream pattern within an alluvial plain?

💡 Explanation

When sediment load increases beyond the stream's transport capacity, aggradation occurs because the excess sediment deposition forms mid-channel bars, forcing the flow to split into multiple, unstable channels, a braided pattern. Therefore excess sediment load results, rather than altered sinuosity, discharge changes or incision which arise through different control factors.

• Which outcome is directly caused by coastal upwelling events along continental margins?
• Which outcome results as cave pH declines via biogenic respiration?
• Which outcome commonly results following extensive groin construction inhibiting longshore sediment transport near barrier islands?
• Which surface deformation results when freeze-thaw cycles and permafrost layer impede drainage on gentle slopes?
