A screening on myxospermic diaspores of 120 species occurring on the Junggar Desert was conducted to: ①examine what species excrete mucilage,and ②compare the sand-holding capacity between different species which excrete mucilage.

The concept of sediment-carrying capacity of wave is theoretically defined and the sediment concentration distribution under the action of waves is deduced.

Correct calculation of sediment-carrying capacity in natural rivers is important for using mathematical models to simulate sediment transport.

Summary of studies on sediment carrying capacity of surface runoff on loess slopes;

A primary research for sediment carrying capacity in Oujiang Estuary;

Under the tidal condition, sediment carrying capacity model must consider the joint action of wave and current.

Application of the　sediment transport capacity models to unsteady sediment transport from overland flow;

Effect of ratio of width to depth of river channel on sediment transport capacity in Lower Yellow River

On the basis of mechanism of sediment exchange,some improvements in relation to the calculation method for riverbed deformation are performed,including modification of dispersion equation of suspended load under the condition of erosion;definition of carrying capacity of non uniform sediment;definition of efficient transport rate of bed load as well as that of time step and space step.
