Old and new concepts based on coherent structures for understanding sediment transport

Albert GYR Coherent structures develop due to an instability process on smooth beds under turbulent flow conditions and they are relevant for the incipient motion of fine sand sediment. Similar flow structures were found to be relevant for the sediment transport under rough wall conditions, but an i...
