Definitions of the geographical regions in the Yangtze River Drainage Basin
Jinsha River: The Yangtze River from Yushu (Qinghai Province) to Yibin in Sichuan province is called the Jinsha River, which has a total length of 3,496 km.
Tuotuo River: The Yangtze River arises from glaciers south of the Geladandong Mountain in Qinghai province and flows west for 343km where it meets with another origin river Danqu and forms the Tongtian River.
Three Gorges Reservoir (TGR):Three Gorges Reservoir stretches along the upstream of the Yangtze River from the boundary of Chongqingmunicipality to Sandouping/Yichang city in Hubeiprovince.
Yangtze Estuary: The YangtzeEstuary occupies 700 km of the river’s 6,300 km length (Fig 1). Chongming Island ramifies the estuary into the South Branch and the North Branch. The South Branch constitutes the main stream of the estuary and receives above 95% of the total estuarine runoff, whereas the North Branch accounts for only about 5%. The main stream of the southern branch is divided into the south channel and north channel by Changxing Island. There are more than 30 branches in the Yangtze estuary, such as Baimao River, Yanglingtang River, Liuhe River, Gujing River, Huangpu River, Xinjianghai River and so on. The longest branch is Huangpu River. The sedimentation rate of the Yangtze estuary is 6.3-6.6 cm yr-1(Wang et al. 2012b).
Yangtze River Delta: including Shanghai, southern Jiangsu province and northern Zhejiang province of China. The Yangtze River drains into the East China Sea. It covers an area of 99,600 km2 and is home to over 105 million people as of 2010, of which an estimated 80 million is urban.
Water Period:In general, the water of the River is at the lowest level in the dry season (December to April), at the highest level in rainy season (from July to September, potential flood events), and at the middle level in normal seasons (May to June and October to November)(Sun et al. 2002).
