Morphology

headrace = head + race (semi-transparent) = head + race

Composed of 'head' + 'race' where 'race' in this sense means a water channel; the technical meaning of 'race' is specialized and may not be known to general learners.

Etymology

Headrace combines head (the 'top' or 'source' of water) and race (to 'run' quickly), so imagine water 'running' from the head toward a wheel. That's why a headrace is the channel that carries water to a mill, water wheel, or turbine for power.
