Tidal bore youtube9/17/2023 ![]() ![]() ![]() The Pororoca river waves have become popular with surfers. The Pororoca tidal bores occur at the mouth of the river where its water meets the Atlantic ocean. The word “ porocca” is driven from the indigenous tulip language where it could translate into “great roar”. The Pororoca is a tidal bore, with waves up to 4 m (13 ft) high that travels as much as 800 km ( 500 mi) inland upstream on the Amazon river and other adjacent rivers. The largest tide on record in the Bay was 21.6 meters ( 70.9 ft) in 1869. Tides in the Bay of Fundy are semi-annual, meaning they have two highs and two lows on each day with about 6 hours and 13 minutes between each high and low tides.Īs per the Guinness Book of World records, the World’s highest tides are found in the Bay of Fundy, where the mean spring range in the Minas basin is 14.5 meters (47.6 feet). Some tides are higher than others, depending on the position of the moon, the sun, and other atmospheric conditions. The tidal range in the Bay of Fundyis around 16 m ( 52 ft). The name is derived from the French word Fendu meaning “split”. ![]() The bay of fundy tidal bore has an extremely high tidal range. The Bay of Fundy tidal bore is the bay found between the Canadian province or territories of New Brunswick and Nova Scotia, with a small part touching the US state of Maine. The bore reached heights from about 5 to 75 cm after the causeway was built. Before the causeway, the value of the Petitcodiac river tidal bore was compared with the tidal bores of Qiantang, Hooghly, and Amazon river. Peter Fisher in 1825, observed that the noise of the bore is heard at a great distance, and animals instantly take to the highland and manifest visible signs of terror if near it. The Petitcodiac River tidal bore ranges from 1 to 2 m (3.3 - 6.6 ft) in height, with a speed from 5 to 15 km/h. The first European mention of the Petitcodiac river tidal bore by the British Lieutenant Colonel George Scott on 17 November 1758. It occurs twice a day and comes from the world’s largest tide in the Bay of fundy. The Petitcodiac River tidal bore - retrograde wave moving upstream over the downstream wavers. Due to the transformation of geographical location from the Ming dynasty, Haining, Hanguan was the first resort to observe the silver dragon tidal bore, so it was also called "Haining Tidal Bore". In ancient Hangzhou, Phoenix mountain, the Jianggan area was the best place to watch the Qiantang River tidal bore. Later, the white line rolled to the sea as it was accompanied by waves of dull thunder. ![]() Before the sea tide appeared, a white ting dot appeared in the distance, which transformed into a silver thread in a blink of an eye. Driving this time, this largest tidal bore can be several meters. Generally around August 15, the Lunar calendar is the best time to observe the silver dragon tidal bores. The Qiantang River tidal bore is a famous scenic spot of the Qiantang River. It is a river in east china and runs from Hangzhou bay on China’s eastern coast. Qiantang River tidal bore, also known as the silver dragon tidal bore, is the world’s largest tidal bore. A tidal bore always occurs during the flood tide and never occurs during an ebb tide. The funnel-like shape not only increases the tidal range but also decreases the duration of the flood tide where the flood appears as an immediate increase in a water level. The word “bore” is derived through Old English from the Old Norse word Bara meaning “ wave” or “swell”.Ī bore occurs in some places worldwide, generally in areas with larger tidal range and where incoming tides are passed into a shallow narrowing of a river of the lake through a broad bay. A tidal bore, also known as the bore is a tidal phenomenon in which the highest incoming tides form a wave (or waves) of water that travels up a river or confined bay against the path of the river or bay’s current. ![]()
