Morphology

river + bottom

The meaning 'the ground at the lowest part of a river channel' is directly and compositionally derived from 'river' (a watercourse) + 'bottom' (the lowest surface). This is a straightforward locative noun-noun combination common across languages, so a B1 learner who knows both constituents will readily understand it.

Etymology

River bottom comes from a simple picture: it is the ground under a river, the actual bottom where stones and sand rest. Because it is the real lowest part of the water, people use it to mean 'the lowest part of a river channel'.
