Morphology

underrun = run (transparent) = under + run

Standard, literal combination of 'under' + 'run' meaning to move or pass beneath something, which an average learner can infer.

Etymology

Underrun is made of under- meaning 'below' and run meaning 'to move', so it literally means 'to run below' something. That's why to underrun a structure or river is to pass or flow under it.
