The team that delivered the hugely successful London 2012 Canoe Slalom course is delighted to see work start on their next Olympic facility in Rio de Janeiro.
The Rio whitewater specialist design team, led by Whitewater Parks International (WPI), includes Cundall whose civil engineering team working on the project is based in Newcastle.
Cundall has prepared the engineering drawings for WPI’s design of the 2016 Olympic whitewater venue that involves the pumping of 12 cubic metres per second for the main channel.
Especially with the compressed timeframe available to complete the Rio project, many of the successful outcomes of the London 2012 facility at Lee Valley have also been applied to the planning of the Rio venue. In developing the London project, Whitewater Parks International worked closely with Cundall engineers to pursue practical and cost effective solutions at every turn. The Cundall and Whitewater Parks International team have continued working closely aiming at reducing the cost of construction, as well as minimising operating expenses so that a vibrant post-Games Legacy can be achieved. The Rio project will certainly have its own unique whitewater character and realise a new standard of improved operational efficiencies.
As part ofthe work in developing the 2016 Olympic Canoe Slalom venue for the city of Rio de Janeiro, the design team have recently directed a scale modelling exercise to confirm critical performance criteria and enhance the final detailing of the soon to be constructed course, part of the “X-Park” inside the Deodoro Zone of the 2016 site.
Czech Technical University (CVUT) in Prague have constructed a tested 1:13 scale hydraulic model of the whitewater channel segments planned for the Rio project. A series of examinations have recently been completed.
This type of modelling is intended to observe hydraulic behaviours in various flow scenarios and structural configurations, the results of which then further inform the final design of the project. Key parameters such as channel geometry, gradient, flow rates and obstacle placement are experimented with and considered as to how exactly they influence hydraulics effects such as depths, velocities, directional shifts, momentum, surging, recirculation and feature formation.
As these myriad factors are assessed, optimal configurations emerge from the testing that demonstrate ample conditions which will meet the International Canoe Federation Technical Requirements for Olympic venues and ensure that the properly delivered facility will be fit for purpose, providing for fair and appropriately challenging Games-time competition.
