Short summary
Rivers flow through aeolian dunes and always adopt braided stream channels in response to aeolian and fluvial sediment supplies. Here our results indicate that these braided rivers are distinguished from coarser-grained thalweg beds and finer-grained bar or floodplain surfaces and develop a significant lateral selective deposition in bed sediment. The traditional downstream fining shows no significance in this braided channel, primarily due to aeolian sand supplies.
