The Yellow River or Huang He / Hwang Ho ( Hatan Gol Queen river) is the second-longest river in China (after the Yangtze River) and the However, the Huai River does not flow all the way to the sea, making it notoriously vulnerable to flooding.
The Huai River-Qinling Mountains line is regarded as the geographical dividing line between North China and South China. The Qinling Mountains ( are a major Mountain range located mainly in the Eastern province of Shaanxi, in China.

The Huai River originates in Tongbai Mountain in Henan province. Henan ( is a province of the People's Republic of China, located in the central part of the country It flows through southern Henan, northern Anhui, and northern Jiangsu, entering the Yangtze River at Jiangdu, Yangzhou. Anhui (in Chinese: 安徽 Ānhuī) is a province of the People's Republic of China. ( Postal map spelling: Kiangsu) is a province of the People's Republic of China, located along the east coast of the country Administration The Prefecture-level city of Yangzhou administers 7 county-level divisions.
Historically, the Huai River entered the Yellow Sea at Yuntiguan ("Escalade Pass") through a broad and level lower course. The Yellow Sea is the name given to the northern part of the East China Sea, which is a Marginal sea of the Pacific Ocean. Escalade is the act of scaling Defensive walls or ramparts with the aid of Ladders and was a prominent feature of Siege warfare in medieval It was long used to irrigate the surrounding farmlands, and was the centre of an extensive network of canals and tributaries. Beginning in 1194, however, the Yellow River to the north repeatedly changed its course southwards to run into the Huai River. The Yellow River or Huang He / Hwang Ho ( Hatan Gol Queen river) is the second-longest river in China (after the Yangtze River) and the The resulting silting was so heavy that after the Yellow River changed back to its northerly course for the most recent time in 1897, the geography of the Huai River basin was changed significantly by the creation of new high lands, lakes, and the built up silt of the Yellow River's historical southern course. Year 1897 ( MDCCCXCVII) was a Common year starting on Friday (link will display the full calendar of the Gregorian Calendar (or a Common As a result, water from the mid-section of the river could not easily flow into the lower section, while water in the lower section could not find an outlet to the sea. The problem was exacerbated in the Second World War, when the government, in an attempt to check the pace of the Japanese invasion, flooded the lower Huai basin by opening the Yellow River's southern levee. World War II, or the Second World War, (often abbreviated WWII) was a global military conflict which involved a majority of the world's nations, including For a topic outline on this subject see List of basic Japan topics. The mainstem of the Yellow River flowed through the levee breach for the next nine years, further disrupting the Huai river system.
The result of these changes was that water from the Huai River pools up into into Lake Hongze, and then runs southwards towards the Yangtze River. Lake Hongze ( is located in Jiangsu Province, China and is encompassed by the cities Suqian and Huai'an. Major and minor floods occurred frequently, with the area suffering droughts in between floods. In the 450 years to 1950, the Huai River saw, on average, 94 major floods per century.
Attempts to solve the Huai River's problems have focussed on building outlets for the Huai River into the Yangtze River and the sea. Currently, the major part of the river's waterflow enters the Yangtze River via Lake Hongze. Lake Hongze ( is located in Jiangsu Province, China and is encompassed by the cities Suqian and Huai'an. The North Jiangsu Irrigation Main Channel also diverts some of its water along its old historical course to the sea, and is planned to be upgraded with a new parallel channel. Several former distributaries also carry some water to the sea.
