The numerical calculation of the 2-D hydrodynamic characteristic in the Pearl River networks around Guangzhou by Ecomsed model based on the observed data of the flood season in 1999 and the drought season in 2001.

The numerical simulation for the Pearl River networks in the area of Guangzhou is calculated by ECOMSED model that is based on the observed data for typhoon No.

3-D visualization and analysis for underwater terrain evolution ofthe Pearl River estuary networks in long-term span;

Based on the theory of regionalized variable and Kriging interpolation approach,spatial variations of water level in river net of the Pearl River Delta are discussed.

Distribution of Polybrominated Diphenyl Ethers in Aquatic Species from the Pearl River Estuary;

Impact of temporal and spatial variation of water environment on ecosystem of the Pearl River estuary;

Impact of Land Use Patterns on Eco-environment in Pearl River Estuary;

Turbulence feature research within bottom boundary layer induced by tide in the Pearl River Estuary

The rapid urbanization in the Pearl River Estuary region,not only could cause the excessive use of tidal flat and the area decreased,but also influence the water environment,and reduce the water area,increase the water pollution,made floods and saline tide occurred frequently.
