The Hydraulics Research Station (HRS) was created by the UK Department of Scientific and Industrial Research in 1947. The Research Station was based in Wallingford, near Oxford. It was established to deal with “looser boundary” problems such as coastal erosion, flood protection and the silting and scouring of rivers, estuaries and harbours. The Hydraulics Research Station was housed at Howbery Park as a government establishment until 1982, when it was privatised from the Department of the Environment (DoE) to become Hydraulics Research Station Limited. It is now known as HR Wallingford. During its existence, HRS contributed to advance hydraulics research. It also worked on water-related projects in the UK and around the world.
1945 - The Institution of Civil Engineers submitted a proposal to the Department of Scientific and Industrial Research on the need for a hydraulics research station in the UK.
1947 – DSIR Hydraulic Research Organisation formed in London
1951 – Hydraulics Research Station established in Wallingford
1965 – Re-organisation into Ministry of Technology. Hydrological Research Unit transferred to the Natural Environment Research Council and later to become Institute of Hydrology and then Centre for Ecology and Hydrology
1971 – Transfer to the Department of the Environment (DoE)
1982 – Privatisation to create Hydraulics Research Station Limited - a company limited by guarantee.
1983 – Hydraulics Research Limited
1991 - HR Wallingford Limited
HRS started doing research in the tidal Thames Estuary back in 1947. At this time HRO (Hydraulic Research Organisation) was based at the National Physical Laboratory at Teddington and had links with a large physical model set up by the Port of London Authority (PLA) in one of their disused warehouses on the Surrey Docks. This model was used to examine many hydrodynamic, sediment, water quality and morphological issues related to the Thames Estuary and the potential redevelopment of the Estuary following the considerable infrastructure damage that had been suffered during World War II. Many of the issues examined and the techniques developed in this pre-computer age formed a remarkably good base from which the modern range and scope of studies have been developed. This has determined the framework for an understanding of the many processes that operate within the tidal Thames Estuary.
