Ulanqab or Wūlánchábù (Mongolian: ; Улаанцав хот, "Uláncaw hot"; ) is a region administered as a prefecture-level city in south-central Inner Mongolia, People's Republic of China.
 Its administrative centre is in Jining District, which was formerly a county-level city.
 It was established as a prefecture-level city on 1 December 2003, formed from the former Ulanqab League.
The Si River () is a watercourse located in Shandong Province and, in ancient time, in Jiangsu Province, China.
 It rises in the southern foothills of the Mengshan Mountains (蒙山) then flows through Sishui County, and the cities of Qufu and Yanzhou before emptying into Lake Nanyang (南阳湖).
 In ancient times the river was a large tributary of the Huai River, converging with the waters of the Fan (反), Sui (睢), Tong (潼) and Yi (沂) and numerous other rivers then passing through present day Yutai County, Pei County, Xuzhou City, Suqian City and Siyang County in Shandong and Jiangsu Provinces.
 At Sikou (泗口) (also known as Qingkou (清口), present day Huai'an City, Jiangsu), the Si River discharged into the Huai River.
 From very early on the Si River was connected with the Huai and Yangtze Rivers as well as the Central Plain of China for a long period in its history.
 In 1194, at the time of the Song and Jin Dynasties, the Yellow River altered its course southwards, engulfing the lower reaches of the Si River below Xuzhou City and those of the Huai River below Huai’an City.
 As a result, the Si River no longer exists in Jiangsu Province.
 In 1855, the Yellow River once more altered its course northwards.
 However, due to the large amount of silt carried by the river, it left behind a 4 to high layer of mud in the lower reaches of the Si River’s former course.
Gaoyou Lake（）is the sixth largest freshwater lake in China, it is located between Anhui Province and Jiangsu Province.
 In a sense Gaoyou Lake is a manmade lake, and its creation is part of a long story about flood control and hydraulic engineering in ancient China.
 Gaoyou Lake is now part of the Huai River system as the Huai River flows south through Gaoyou Lake on its way to the Yangtze River and the Pacific.
 It is about 39 km long and 30 km wide, covering approximately 674.7 km.
The North Jiangsu Main Irrigation Canal (, ) (often called the "Subei Canal") is located in the lower reaches of the Huai River, one of the major rivers of northern Jiangsu Province in eastern China.
 It originates at Gaoliangjian on Hongze Lake and runs through Hongze, Qingpu, Huai'an, Funing, Sheyang and Binghai county(or district) and joins the artificial estuary of Biandan Harbour.
 The canal is 168 km in length and can irrigate 1,720,000 hectares of farmland.
 The construction program was organized and directed by the headquarters of the Jiangsu Huai River management program between October 1951 and May 1952.

The Huai River, formerly romanized as the Hwai, is a major river in China.
 It is located about midway between the Yellow River and Yangtze, the two largest rivers in China, and like them runs from west to east.
 Historically draining directly into the Yellow Sea, floods have changed the course of the river such that it is now a major tributary of the Yangtze.
 The Huai is notoriously vulnerable to flooding.
