What are the three strong tidal bore rivers in the world?
Qiantang river 1
Qiantang River is the largest river in Zhejiang Province. It is the source of the naming of Liangzhe Road in Song Dynasty, and also the source of Zhejiang's provincial name when it was established in the early Ming Dynasty. It starts from Xin 'anjiang in the north, with a total length of 588.73 kilometers; It starts from Ma Jinxi in the upper reaches of Qujiang River in the south, with a total length of 522.22 kilometers. From the source, it flows through southern Anhui Province and Zhejiang Province, with a drainage area of 55,058 square kilometers, and flows into the East China Sea via Hangzhou Bay.
2. Ganges River
Ganges River, also translated as Gaga River, Qiangga River and Gangdise River in Chinese, is a big river in South Asia, with two trunks, originating from the southern foothills of Himalayas and Deccan Plateau.
After flowing through the Indian states of Uttar Pradesh, Uttar Pradesh, Bihar, Debon, culkin and West Bengal, it enters Bangladesh, renamed Padma River, flows into Jamuna River in the lower reaches of Brahmaputra River in Bangladesh, and finally flows into the Bay of Bengal, and its reach into the sea is called Meknell River.
3. Amazon River
The Amazon River is the second longest river and the largest river in the world. Its river flow reaches 210.9 million cubic meters per second, which is several times larger than the sum of the other three rivers, namely Nile (Africa), Yangtze River (China) and Mississippi River (USA), equivalent to the flow of seven Yangtze Rivers, accounting for 20% of the world's river flow. The basin area is 6910.5 million square kilometers, accounting for 40% of the total area of South America. The number of tributaries exceeds 6.5438+0.5 million.
Extended data
One of the most famous tidal bore in the world is the Qiantang River Tide in China. It is a tidal wind that occurs in Hangzhou Bay (the mouth of Qiantang River). Because Hangzhou Bay is a big bell mouth with a wide outside and a narrow inside, the width of the estuary 100 km is reduced to about 20 km near Ganpu. When it arrived in Yan Guan, the river was only 3 kilometers wide at low tide. Every time the tide rises, the river will swallow a lot of seawater and push it in.
Due to the sudden narrowing of the river, the tide surged and reached its climax. Coupled with the huge underwater sandbar to the west of Ganpu, the average water depth of the riverbed dropped rapidly from about 20 meters to 2 -3 meters, forming a "threshold", which was blocked by the tide, and the latter wave caught up with the previous wave, forming an upright "water wall" with a tidal range of 3.5 meters and a tidal range of 8.9 meters. This is the most famous tidal bore in the world.
