Morphology

river + basin

The compound meaning is directly derived from its parts: 'river' (a flowing watercourse) + 'basin' (an area where water gathers/drains) yield an area drained by a river. This compositional pattern is literal and cross-linguistically common, so a B1 learner who knows both words would readily infer the MWE meaning.

Etymology

River basin comes from the image of a land basin or bowl around a river where rain and small streams all flow down into the river. So, it means the 'area of land that sends its water to one river'.
