HR Wallingford began with the creation of the Hydraulics Research Organisation (of the Department of Scientific and Industrial Research) in 1947.   Continue reading ›

70 years of modelling the tidal Thames

Posted: 09-Mar-2017

We have been modelling the Tidal Thames since the company's early days, and the Thames remains an important focus of our work. 

One of our longest running studies has been on the Thames Barrier. Following the East Coast Floods of 1953, often described as the worst national peacetime disaster to hit the UK, survey teams were sent to inspect the damage on the East Coast, and a small model of the Thames was used for a preliminary study of flood protection in London and on the estuary. The effect of a surge-reducing barrage was tested on behalf of the Waverley Committee, and this model became the forerunner of a larger model built to study the same problem years later. Starting in 1968, the Hydraulics Research Station was commissioned to undertake studies to predict how the construction and operation of a barrier at different sites would affect river levels, tidal currents and siltation in the Thames. Many other computer, physical modelling, monitoring and laboratory studies were carried out to refine the barrier plan in the 1970s leading to the Thames Barrier becoming operational in 1984.  Continue reading ›

Developing state-of-the-art wavemakers

Posted: 07-Mar-2017

HR Wallingford has been developing and improving wavemakers since the 1940s.  Click on the image above to view our wavemaker timeline which shows the evolution of our wavemakers, from the early manually-operated wavemakers, to the wheeled-crank mechanisms used in our outdoor basins in the 1950s, right through  to today's digital and remotely-operated multi element wavemakers, and virtual coded waves. Continue reading ›
