An Introduction to Longitudinal Profile Formation and Reasons for Continued Siltation in the Lower Yellow River Course

Abstract:The author considers that the process of landform of the lower Yellow River is the process of razing and we can not say that is the parallel siltation of the river bed. It has been clear through conceptualized flume simulation that even if the river mouth stops its siltation and extension, the lower Yellow River will be silted and raised continuously. It is no grounds if it states that the Yellow River course is silted and raised due to siltation and extension of the river mouth. The continued siltation and raise of the lower Yellow Riv er is caused by so much on-coming sediment and weak capability of sediment carrying, while the weak capa bility is caused by the characteristics of gentle gradient and wide and shallow section that are formed under the historical conditions. Part of siltation at the mouth belongs to the category of along-course siltation, the others belong to the part of backward siltation, effecting the lower part of Shandong section only.
Keywords:channel evolution   longitudinal profile of river bed   channel siltation   siltation at river mouth   the lower Yellow River course
