What is going on with the Yellow River seizing the Huai into the sea .

The estuary of the Yellow River is in Shandong, but he walked into the Huai River and into Jiangsu, and the estuary is in Jiangsu! The meaning is simple and straightforward.

It is the diversion of the Yellow River to the Huai River, from the mouth of the Huai River into the sea.

The seizure of the Huai River into the sea refers to the fact that the Yellow River used the course of the Huai River to form an estuary between 1194 and 1855. According to historical records, the Yellow River has encroached on the Huaihe River basin several times, but it was relatively short and did not change much to the Huaihe River basin.

However, since the fourth major diversion in 1194, the eastern Henan, northern Anhui, northern Jiangsu and southwestern Shandong regions of the Huaihe River basin have become areas where the Yellow River often floods. The 661-year-long encroachment of the Yellow River has brought about major changes in the water system of the Huaihe River Basin.

The main reason: the ancient Huai River water system, generally the main stream of the Huai River that flows into the sea alone, and many tributaries of the north and south of the main stream. The tributaries of Huaibei are mainly Hongru River, Yinghe River, Whirlpool River, Biansi River, Yishu River, etc.

Among them, the tributary water system has changed the most. The ancient Surashui source flows out of Mengshan Mountain, passing through Qufu, Yanzhou, and Pei County to the northeast corner of Xuzhou. In Pi County, there will be Yishui and Shushui, and in the south of Suqian, there will be water.

The upper part of ancient Surabaya is similar to the modern Si River, and the lower part has been replaced by the Nansi Lake and the Middle Canal due to the Yellow River. The area of the ancient Surabaya basin was larger than the area of the Yishu River system above the present-day Luoma Lake, and it was the largest tributary of the Huai River at that time.

The Huai River was originally an outflow river, that is, the water of the Huai River would eventually flow from the land into the sea, and the Huai River originally had its own inlet channel. It is a river that flows into the sea alone. However, due to the water system and geomorphology of the Huaihe River Basin, the middle and lower reaches of the Yellow River have been diverted many times in history, especially the Yellow River's seizure of the Huaihe River into the sea, silting up the downstream channel into the sea (i.e., the abandoned Yellow River), and the flood drainage is not smooth and overflowing.

The encroachment on the inflow of the Huai River into the sea has caused the original Huai River water system to be disordered, resulting in frequent natural disasters, or floods or droughts. Since then, the Huai River has entered an eventful autumn.

In the second year of the reign of Emperor Shenzong of the Song Dynasty (1069), the Yellow River flowed into the sea in the east, which was the result of human intervention and blocking the north flow. Since then, the Yellow River has drifted between the northward flow of the breach and the forced eastward flow.

1) In 1081, it flowed north at the Xiaowu Si Junction in Lanzhou, and still entered the sea from Tianjin;

2) During the reign of Zhezong, the project of flowing east of the Hui River was built one after another, and by 1092, most of it had flowed eastward;

3) However, only a few years later, in 1099, the Yellow River broke through the Neihuang River again, and the northward flow was extinct. So far, the project of returning to the east of the river that the Northern Song Dynasty worked hard to manage has completely failed. As contained in the History of the Song Dynasty:

After repeated blockades, they crossed to the south and then fell to the Jin Yuan clan (i.e., the Jin dynasty that ruled the middle and lower reaches of the Yellow River)."

As I said upstairs, the Yellow River was diverted, so it was like this, and the Yellow River diversion was recorded in history, and there were 7 times. Here are the times and reasons for the record: Number of times Time Place of entry into the sea Reason for diversion First time 602 B.C. Cangzhou into the Bohai Sea Nature Second time 11 A.D. Binxian, Lijin into the Bohai Sea Natural, man-made The third time 1048 A.D. The north flows from Tianjin to the Bohai Sea, and the south flows from the Wuli Duma River to the Bohai Sea Nature Fourth time 1194 A.D. Qingjiang Estuary, Yuntiguan into the sea Natural, man-made Fifth In 1494 A.D., the Huai River entered the sea, natural, man-made Sixth 1855 A.D. Lijin entered the Bohai Sea Natural, man-made Seventh A.D. 1938 The Huai River entered the sea Man-made What you are talking about is the seventh time Specifically: In 1938, Chiang Kai-shek ordered to open the embankment of the Yellow River at the mouth of the Huayuankou in Zhengzhou, and the whole river flowed southward, along the Jialu River, the Yinghe River, and the Whirlpool River into the Huai River.

The flood was overflowing, and the victims were everywhere. It was not until 1947 that the Yellow River returned to the north and entered the sea from Kenli County, Shandong. That's it.

The estuary of the Yellow River is in Shandong, but he walked into the Huai River and into Jiangsu, and the estuary is in Jiangsu! The meaning is simple and straightforward.

It is the diversion of the Yellow River to the Huai River, from the mouth of the Huai River into the sea.

The course of the Yellow River was diverted to flow into the Huai River.

The Huai River enters the sea with a newly built artificial river channel and a main irrigation canal in northern Jiangsu, which is injected into the Yellow Sea; It can also enter the sea through the Yangtze River, which is injected into the East China Sea.

Remember to adopt it!

The main stream of the Huai River flows from west to east, through the southern part of Henan Province and the central part of Anhui Province, and flows into Hongze Lake in the central part of Jiangsu Province.

Historically, the Huai River was emptied into the Yellow Sea

The current Huai River, below Hongze Lake is the lower reaches of the Huai River, and there are three estuaries to the sea. The main stream flows into the Yangtze River The main stream flows into the Yangtze River through the Sanhe Gate and passes through Baoying Lake and Gaoyou Lake at Sanjiangying, which is a waterway into the Yangtze River, with a total length of about 1,000 kilometers and flows into the East China Sea.

the other road exits the Gaoliangjian Gate on the east bank of Hongze Lake, and enters the Yellow Sea at Biandan Port through the North Jiangsu Irrigation Canal;

The third road exits the Erhe Gate on the northeast shore of Hongze Lake, passes through the Huaishu River, and flows into Haizhou Bay (Yellow Sea) at Linhongkou.

After the Yellow River flooded into the Huai River, it entered the sea from the original estuary of the Huai River, because the Yellow River carried a large amount of sediment in the water, the Huai River entered the sea and the old road was silted up by the Yellow River, and the Huai River could not directly enter the sea, and was forced to flow into the river from the three rivers below Hongze Lake.

After the founding of the People's Republic of China, in view of the current situation of continuous floods in the Huaihe River and Hongze Lake basins, the Huaihe River inflow channel was renovated, the main irrigation canal in northern Jiangsu where Hongze Lake flows into the sea was excavated south of the abandoned Yellow River, and the Sanmenxia Hydropower Station and the Xiaolangdi Hydropower Station were successively built in the main stream of the Yellow River in the 60s and 90s. In this century, the Grand Canal was dredged, and the Hongze Lake drainage channel was excavated in parallel along the main irrigation canal in northern Jiangsu.

Historically, the Huai River had an estuary, and when the Yellow River seized the Huai River into the sea, the water flowed into the ocean from the Huai River. The Yellow River has a large amount of cement and sand, and later the flood water was reduced, and the sediment deposits in the river water raised the riverbed in the lower reaches of the Huai River, and the Huai River lost its natural channel into the sea. The water of the Huai River passes through the main irrigation canal in northern Jiangsu; It flows into the Yangtze River and then into the ocean.

Now people have built an artificial channel for the Huai River to enter the sea to control the flooding of the Huai River.

Doesn't it mean that the Yellow River was diverted from the Huai River into the sea in history?

Due to the accumulation of sediment in the Huai River, the downstream is high, so the two ends are high, the middle is low, so it is prone to flooding, in addition to the uneven precipitation in the rainy season and the drought is serious, and the pollution on both sides of the Huai River is more serious, so the Huai River has really become a harmful river.

The seizure of the Huai into the sea was caused by the control of the Yellow River. It became a bad river because of the large amount of pollutants discharged into the Huai River.

In the 50s, washing rice and vegetables, in the 60s, washing and irrigating, in the 70s, the water quality was corrupted, in the 80s, the fish and shrimp were extinct, and in the 90s, there was sparse cancer.
