AbstractBased on data from rivers in the Huanghuaihai Plain of China, an attempt has been made to deal with the mechanism for the formation of alluvial river longitudinal profile concavity. The profile concavity can be related to the manner in which the energy expenditure is distributed along the river length. If the river has a heavy sediment load when flowing into the plain, it needs to keep a relatively high level of energy expenditure to carry sediment, then the channel gradient will not be allowed to decline rapidly downstream, and a longitudinal profile with low concavity is achieved, and vice versa. In addition, if the water discharge increases and sediment concentration decreases rapidly along river length, a high concavity of longitudinal profile will occur. The river longitudinal profile concavity has a close relation with river channel patterns, the river with longer wandering braided reach having a lower concavity of longitudinal profile. Profile concavity can be regarded as one of the adjustable variables in river channel processes, and based on this concept an explanation has been given concerning the formation of climaticogenetic terraces.
