Which mechanism causes braided river channel formation within an alluvial plain environment?

💡 Explanation

When sediment load exceeds the river's transport capacity, aggradation occurs because the excess sediment gets deposited as bars within the channel, forcing the flow to split and form a braided pattern. Therefore, decreased sediment transport occurs, rather than stabilization, subsidence, or base level control which promote single channel river forms.
