Morphology
The meaning 'an area of land from which precipitation collects and drains' is directly and compositionally derived from 'catchment' (a place where water gathers) plus 'area' (a region). This compound follows a transparent noun+noun pattern found across languages, so a B1 learner who knows both constituents would readily infer the MWE meaning.
Etymology
The noun catchment area comes from the image of catchment meaning land that 'catches' rain and area meaning a place or space. Like a bowl that gathers water and pours it to one river or lake, the catchment area is the place 'where water collects' and flows to the same river or lake.
