A direct compound of 'river' + 'bed' whose meaning 'the bottom of a river' is straightforward for learners who know both components.

Etymology

The word riverbed is made from the common words river ('flowing water') and bed ('place to lie'), so imagine the 'bed' where the river lies. So, riverbed means the ground at the bottom of a river where the water flows or once flowed.
