摘 要:Pearl River Delta (PRD) is one of the most developed areas
in the southeast coast of China. The flood control security
of PRD plays an important role in the regional social and economic
sustainable development. Because of the complex constitute of
rivers, river mouths and coastal area of PRD, together with
the collective influences of run-off and tide, the flood flow
hydrodynamic characteristics in PRD shows extremely complex
temporally and spatially. Based on analysis of the water system
constitute and hydrodynamic feature of PRD, the present paper
developed a systematic hydrodynamic model that covers rivers
and river months and coastal area in the water system as a whole.
Model calibration and verification are made depending on newly
observed distributive data. The developed model is applied in
analyzing flood flow characteristics and causes of the exceptional
flood elevation rise in the hinterland of PRD since late 90's.
The research would be very useful in supporting decision making
for flood control in the region.
