Transport behaviour of solids

Concentration distribution of the solids (5)

Subsequently, the transport states in relation to the average flow velocity, shown in the figure, are explained further:

Transport state c), floating and sliding motion is characterized by the increased solids concentration at the channel base and the presence of sediment. The solid particles float and slide through the channel without settling [Führb62] [SteinR2005].
