Title: Numerical Simulation of Hydrodynamics and Sediment#br#Transport in Tidal Pearl River of Guangzhou
Abstract: Based on EFDC(Environmental Fluid Dynamic Code) model,a three dimensional numerical hydrodynamic and sediment transport model in Pearl River network of Guangzhou(PRGZ),was developed.The result indicated that the model was able to simulate hydrodynamics and sediment transport characteristics with fairly good accuracy verified by typical flood scenario case in July 1999 and dry scenario case in February 2001.The sediment transport result showed that Pingzhou to HouHangdao were the major transportation channel for suspended sediment during flood season.Erosion and deposition simulation also showed that PRGZ tended to deposition in flood season with Nanhandao and Lijiaoshuidao as the major deposition area.In the dry season,PRGZ tended to erosion,which usually happened in Shabeihai,Qianhangdao upper section and Xinzao rivernet.Besides,the entire rivernet showed a slow deposition rate,approximately at a speed of 2.0 cm/a.
