RapidBlocs are a movable obstacle system for artificial whitewater courses.
[1] The system was developed for the Lee Valley White Water Centre that was used for the 2012 London Olympic Games.
[2] The system is made of modular blocks that can be secured via unistruts at any point in a compatible channel.
These shapes are configured to create waves, eddies other hydraulic jumps.
The system has been used in a variety of channels that were either custom built for the system or have been retrofitted to an existing channel – as in the case for the Tees Barrage International White Water Course[3] and the Prague-Troja Canoeing Centre in Prague.
