Title: River Training and Equilibrium Sediment Transport of the Lower Yellow River
Abstract: The basic way of increasing the channel capacity of sediment transport is to reduce the resistance loss of river bed.It will be favorable to the stability of main channel and equilibrium sediment transport,in addition to the radius of curvature in a river bend which suits to discharge,narrow and deep channel,smooth and continuous bend protection works and the joins of flow regime between each bend.Slope is an important factor to affect the capacity of sediment transport.The slope of the Yellow River channel downstream of Gaocun,especially downstream Aishan reduces greatly.Only the river width is narrowed correspondingly can reach the same capacity of sediment transport of the upper stream.Building submerged groins can reduce the sedimentation of small-slope section downstream Aishan during non-flood season.The sediment carrying capacity of the Yellow River flow is not only related with hydraulic factors and sediment grain size,but also increased with the increase of sediment concentration,having multi-valued relationship and the characteristics of implicit function.
