In this type of river surfing, the wave is stationary on the river, caused by a high volume of water constricted by flowing over a rock and creating a wave behind. It is a form of hydraulic jump. A river surfer can face up-stream and catch this wave and have the feeling of traveling fast over water while not actually moving.
Despite being many hundreds of kilometres from the nearest ocean, Munich has a reputation as a surfing hotspot. The city has been the center of surfboard riding on a stationary wave since the mid-1970s. Up to 100 surfers daily hit the waves in the city's Englischer Garten. There, in the Eisbach river, the flow velocity of the icy water is about 5 meters at a rate of 20 tons per second, and the temperature never gets above 15 degrees Celsius. An annual surfing competition is held on the standing wave. Additionally, there are further stationary waves that form on the river Isar just downstream of the Wittelsbacherbrücke bridge in Isarvorstadt, as well as on the canal that joins the Isar channel with the Floßlände. Munich has produced the best river surfers and was the first location that created a true surfing community around an inland river wave.
Norway has several river waves, amongst the most famous are Bulken in Voss and an unnamed river wave in Sarpsborg. Oslo are in the planning phase of building a potential, artificial river wave in their main city river Akerselva.
The Habitat 67 standing wave in the Lachine Rapids in Montreal, named for its location adjacent to the Habitat 67 housing complex, has become a popular destination for river surfing. Corran Addison, an Olympic kayaker and three-time world freestyle kayak champion, was the first to surf the Habitat wave in 2002. His river-surfing school, Imagine Surfboards, has taught 3,500 students since 2005. A second Montreal river-surfing school, KSF, has hosted 1,500 students a year since 2003. From fewer than 10 original surfers, it is estimated that the current of participants numbers around 500.
Pueblo, Colorado has also became a river surfing city. A kayak park was in built 2005 near downtown Pueblo and locals have been surfing features 3,4, and 7 ever since.
Missoula, Montana has surfing on Brennan's Wave, a man made wave on the Clark Fork River.
The world's first commercial river surfing operation was started by Jon Imhoof in 1989. Trips are run on the Kawarau River near Queenstown. Bodyboards are used to run rapids and ride standing waves on the river.
Tidal bores occur in relatively few locations worldwide, usually in areas with a large tidal range (typically more than 6 metres (20 ft) between high and low water), and where incoming tides are funnelled into a shallow, narrowing river via a broad bay. Large bores can be particularly dangerous for shipping, but also present opportunities for river surfing. The funnel-like shape not only increases the tidal range, but it can also decrease the duration of the flood tide, down to a point where the flood appears as a sudden increase in the water level. Note the tidal bore takes place during the flood tide and never during the ebb tide.
A tidal bore can create a powerful roar that combines the sounds caused by the turbulence in the bore front and whelps, entrained air bubbles in the bore roller, sediment erosion beneath the bore front and of the banks, scouring of shoals and bars, and impacts on obstacles.
Surfing the Severn Bore has become a competitive sport with dozens of surfers vying to record the longest ride. The tidal surge also attracts canoeists and windsurfers. The present champion surfer is Dave Lawson from Hempsted, Gloucestershire, who has covered 5.7 miles on a surfboard. His record-breaking surf took more than 35 minutes and was logged by an official adjudicator from the British Surfing Association.
The Petitcodiac River tidal bores—retrograde waves moving upstream over downstream waves—occur twice a day and come from the world's highest tides in the Bay of Fundy.
The North American record for surfing a single river wave was set by JJ Wessels and Colin Whitbread of California, who rode the Petitcodiac River's tidal bore for 29 kilometres on July 24, 2013.
