Morphology

tidal + river

The noun phrase is fully compositional: 'tidal' (pertaining to tides) modifies 'river', so a B1 learner who knows both words can infer it is a river affected by the rise and fall of the tide. This adjective+noun pattern is regular in English and common cross-linguistically, making the meaning directly derivable from the parts.

Etymology

Tidal river comes from a simple picture: the tide from the sea pushes into a river, so the river level goes up and down. That's why it means 'a river where the sea's tide reaches and makes the water rise and fall far inland'.
