The adverb 'herüber' (over here/across) consists of two parts: 'her-' and 'über'. The prefix 'her-' always expresses movement toward the speaker, while 'über' describes movement over a boundary or distance.

The ball rolled over to us from the other playing field.
'herüber' (over here/across) is very often combined with verbs of movement and then forms a separable verb. The prefix 'herüber-' comes at the end in a main clause.
Meine Nachbarin winkte mir vom Balkon herüber.
My neighbor waved over to me from the balcony.
Common verbs that are combined with 'herüber' (over here/across) are 'herüberkommen' (to come over), 'herüberschauen' (to look over / come by), 'herüberwinken' (to wave over), and 'herüberreichen' (to pass over). They all describe an action directed toward the speaker across a distance.
Schau mal, die Katze vom Nachbarn kommt zu uns in den Garten herüber.
Look, the neighbor's cat is coming over into our garden.
The use of 'herüber' (throughout) for a period of time is rare and is considered outdated or literary. In modern German, this meaning is hardly used anymore.
Das ganze Jahr herüber gab es kaum einen Tag ohne Sorgen.
Throughout the whole year, there was hardly a day without worries.

'über' and 'herüber' can both have to do with movement from one side to the other. 'über' is a preposition and usually needs a noun, for example 'über die Straße' (across the street) or 'über die Brücke' (over/across the bridge). It describes the path. 'herüber' is an adverb and emphasizes the direction toward the speaker or toward the place currently being talked about. Learners may confuse the words because both can express movement across a boundary or distance. Memory tip: 'über' says what someone goes over or across; 'herüber' says that someone is coming over here.
