I have two polygon layers, where one is river catchments and the other is subcatchments. I want to identify which catchment each subcatchment belongs to. So I would like either a list where each subcatchment is related to their catchment, or to get the catchment names added to the attribute table for the subcatchment layer.

I have done a lot of searching but have not found anything that answers my questions.
