I am editing a friend's scientific manuscript, which will ultimately be submitted to a biological journal. He uses "just" as an adverb to describe a location (emphasis added by me), e.g.,
The river's confluence is located just downriver from the site.
However, the use of "just" seems too colloquial to me for scientific writing, although I cannot pinpoint exactly why I dislike the use of "just". Am I correct in my assessment that "just" should be wordsmithed out? e.g.,
The river's confluence is located immediately downriver from the town.
The exact distance (e.g., 100 m vs 1 km) is not important because this is a caption to map. Also, I have looked at other "just" questions on this site. This post is similar but non-technical. An answer to this post suggests that "just" can be ambiguous, which might be another reason I might dislike the use of "just". Also, my question is not relevant to this post or this post on "just".
