Hydraulic analysis is a key water management tool, enabling Buro Happold’s engineers to carry out a range of studies from surge analysis in rivers to detailed modelling of flow characteristics in utility pipes, sewers and pumped networks. In water supply systems we use advanced 3D computer simulations to test for pressure (head) loss and the operational efficiency of hydraulic components. This data allows us to provide innovative and cost-effective design solutions for optimising water flow.

In environmental water engineering, we assess how physical changes in a river or floodplain can affect the conveyance of flood flows. These changes may include the construction or relocation of bridges and culverts, channel modifications, excavation, the depositing of fill or new development in the floodplain. In the marine environment, we carry out risk and performance assessments of jetties, bridges and offshore structures by analysing the hydraulic loading caused by wind, waves and currents.

Hydrological modelling plays a vital role in effective water management. The technique is used to simulate the movement of groundwater and rainfall run-off, enabling us to assess flood risk, improve decision-making about protection measures and mitigate the damage caused by flooding, which currently costs around £1.4 billion annually. Models are also used to forecast the dispersal of chemical pollutants into rivers and estuaries and the build-up of sediment caused by estuarine barrages.
