Transport in the Pearl River Estuary by Dr. WAI Wing-Hong, Onyx (PolyU)  |
| The Pearl River
estuary (PRE) plays a major role in the social, economic and cultural development of Hong
Kong, Shenzhen, Guangzhou, Zhuhai, Macau and other cities in the Pearl River Delta region.
The population of the Pearl River Delta is over 20 million. The estuary supports a wide
variety of fish and invertebrates that are of both fisheries and ecological
interest.Moreover, PRE is a natural habitat of the Chinese white dolphin which is
identified as a highly endangered species. In the recent years, the rapid economic growth
in the Pearl River Delta region attracts many large-scale port and waterway projects in
PRE including newly proposed projects, for example, the Tonggu Waterway project. To
minimize the construction, operation and maintenance costs and possible environmental
impacts of theseprojects, a good quantitative understanding of the sediment fate and
transport characteristics in PRE is necessary. (More
