Wave basin E at HR Wallingford is a multi-purpose wave and current basin (formally known as the UK Coastal Research Facility). It is equipped with four reversible axial flow pumps, giving a total discharge of 1.2m³s-¹. This facility can be narrowed to produce a wide current flume, while wave paddles can be installed to produce a wave and current flume. Tests have been conducted with waves and currents at right angles and in the same direction. It has been used to test the response of floating structures, mooring loads, scour at foundations and forces on fixed structures.
