The river delta, also known as the
Golden Delta of Guangdong, is formed by three major rivers, the
Xi Jiang (West River),
Bei Jiang (North River), and
Dong Jiang (East River). The flat lands of the delta are criss-crossed by a network of
tributaries and
distributaries of the Pearl River. The Pearl River Delta is actually two
alluvial deltas, separated by the core branch of the
Pearl River. The Bei Jiang and Xi Jiang converge to flow into the
South China Sea and Pearl River in the west, while the Dong Jiang only flows into the Pearl River proper in the east. The Xi Jiang begins exhibiting delta-like characteristics as far west as
Zhaoqing, although this city is not usually considered a part of the PRD region. After passing through the
Lingyang Gorge and converging with the Bei Jiang, the Xi Jiang opens up and flows as far east as
Nansha District and as far west as
Xinhui. Major distributaries of the Xi include Donghui Shuidao, Jiya Shuidao, Hutiaomen Shuidao, Yinzhou Hu, and the main branch of the Xi Jiang.
Jiangmen and
Zhongshan are the major cities found in the western section of the delta. The Bei Jiang enters the delta plains at
Qingyuan but does not begin to split until near
Sanshui. From here the two main distributaries are Tanzhou Shuidao and Shunde Shuidao which form multiple mouths along the west side of the Pearl River's estuary. Two other distributaries, and Xinan Cong, split from the Bei further north and converge with the Liuxi He to form the main branch of the Pearl River just north of
Guangzhou. The other major city in the north section of the delta is
Foshan. The Dong Jiang flows through
Huizhou into the delta. It begins diverging northeast of
Dongguan into many distributaries, including the Dongguan Shuidao. Distributaries enter the Pearl River as far north as
Luogang and as far south as
Hu Men (Tiger Gate).
Saltwater crocodiles were present within the Pearl River estuary during antiquity. == Location and demographics ==
