Qiantang river bridge is 1453 meters long, 9.1 meters wide and 71 meters high. The upper deck of the bridge is a two-way two-lane highway with a design speed of 100 km/h, and the lower deck is a single-track railway with a design speed of 120 km/h. [32] During World War II, the Qiantang River Bridge was hit by Japanese air raids.
The clock of 1667 at Fécamp Abbey shows the time of local high tide, and the present state of the sea by means of a disc with a quarter-circle aperture which rotates with the lunar phase, revealing a green background at the syzygies (at new moon and full moon), when the tidal range is most extreme ("spring tides"), and a black background at ...
A bore in Morecambe Bay, in the United Kingdom Video of the Arnside Bore, in the United Kingdom The tidal bore in Upper Cook Inlet, in Alaska. A tidal bore, [1] often simply given as bore in context, is a tidal phenomenon in which the leading edge of the incoming tide forms a wave (or waves) of water that travels up a river or narrow bay, reversing the direction of the river or bay's current.
Yanguan tidal bore (2017). The Bay is known for hosting the world's largest tidal bore, up to 9 meters (30 feet) high, and traveling up to 40 km (25 mi) per hour. Yanguan Town Tide-Viewing Park (盐官镇观潮胜地公园 Yánguān Zhèn Guāncháo Shèngdì Gōngyuán), on the north shore of Hangzhou Bay some 50 km east of the city of Hangzhou, is regarded as one of the best place to watch ...
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or "tidal range").
In the past, it was ten li (a Chinese unit of length, one li = 1/2 kilometre) away from Xiaoshan County and served as the western starting point of the canal. It used to be a barrage, which was then transformed into a gate in the fifteenth year during the reign of Wanli emperor to resist the tides from the Qiantang River (Chinese: 钱塘江 ...

Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...
