for straight embankments, cuttings, slopes, if they are done with an area that shares nodes, then I don’t think you need a relation. if they are jsut two lines that happen to be near each other, and do not share nodes, you might need a relation to associate them.
also, if a levee is made of two separate embankments, with a =dyke way in the center, those might need t obe related.

No need for relations for that.
