Influence of flood wave type on sediment transport in lower reaches of Yellow River;

Three-dimensional modelling of sediment transport in the Pearl River Estuary;

Study on sediment transport in the lower Yellow River during flood period;

Since the coast of the Bohai Bay is a typical plain silty one,the problems about engineering sediments,such as fine sediment transportation and how to reduce silting amount for the port and waterway,have come across one after another in the construction of the Tianjin Port and the Huanghua Port of Hebei Province,the two largest artificial ports in China.

According to meteorological factor and underlying surface condition of the watershed both Jinsha river and Jialing river in Yangtze upstream river, the probability of Yangtze upstream river changing into second Yellow river are studied based on surface erosion, sediment transportation, water and soil loss, as well as human activity.

?137)Cs──an artificial radioactive isotope which is resulted from weapons testing mainly in1950s and 1960s was used as a tracer in soil erosion and sediment transportation.

Effect of erosion control measures on sediment delivery ratio;

Research methods and results analysis of sediment delivery ratio

This paper reviews the previous studies on the relationship between sediment delivery ratio and drainage area which reflects essentially the relationship between sediment yield and drainage area.

The channel sediment delivery ratio(SDR)of the Yichang-Wuhan reach in the middle Yangtze River has been determined using the concept of sediment budget at channel-reach scale,based on which the variation in SDR from 1956~1997 has been studied in response to the variation in sediment load and flow inputs.
