River surfing
River surfing is the sport of surfing either standing waves, tidal bores or upstream waves in rivers. Claims for its origins include a 1955 ride of 2.4 km (1.5 mi) along the tidal bore of the River Severn.
River surfing on standing waves has been documented as far back as 1972 on an artificial wave created on a section of the Eisbach man-made river, a side arm of the Isar River, near Haus der Kunst in the Englischer Garten park in Munich, Germany, today offering the world's largest urban surfing spot.
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. A requirement for this is a flowing water with shallow depth in which the inertia of the water overcomes its gravity due to the supercritical flow speed (Froude number: 1.7 - 4.5, surpassing 4.5 results in direct standing wave) and is therefore neither significantly slowed down by the obstacle nor pushed to the side. 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.
River surfing conditions are created by a combination of underlying rock formations and specific water levels, i.e. not too much or too little water. Water flow is usually measured in the SI-unit cubic meters per second (m3/s) (alternatively in liters per second or cubic feet per second).
Despite being many hundreds of kilometres from the nearest ocean, Munich has a reputation as a surfing hotspot, offering one of Europe's best waves. The Bavarian capital is the birthplace of river surfing. The city has been the center of surfboard riding on a standing wave since the early 1970s. "Dieter Deventer has been doing this since 1973". Up to 100 surfers daily hit the waves in the city's Englischer Garten, the largest urban park in the world. There, in the river Eisbach, the world's best known river surf spot, the Eisbach (literally “ice brook”) wave, the flow velocity of the icy water is about 5 meters per second, at a flow rate of 20 m3/s (equivalent to a mass 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 standing 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. The scene has around 1,000 active surfers, while 10,000 in Munich will have tried it at some point.
On Austria's river Mur in Graz (Styria), river surfing is a regular on two waves built for surfing in 2001 and rebuilt in 2004 by KanuClub Graz. Near Salzburg in the Alm Canal there is a custom built surf wave, the Almwelle.
Norway has several river waves, amongst the most famous are:
