A headwall is: ‘The retaining wall at a culvert inlet or outlet that provides support to the embankment. The headwall is normally at right angles to the culvert barrel, but may be skewed. The headwall may have wingwalls at an angle to the headwall that provide support to the channel sides and form part of the transition from channel to culvert and vice-versa.’
