I read an article in Journal of Hydrology and am dumbfounded by errors. I cannot believe the reviewers and the editor didn't catch them.
Recently I saw several dumbfounding errors in articles in highly-cited journals. They don't change the conclusions of the studies, but it's shame anyway.

A U.S.-born American citizen is being detained at the request of immigration authorities despite an advocate showing his U.S. birth certificate in court and a county judge finding no reason for him to be considered an “illegal alien” who illegally entered Florida.

Juan Carlos Gomez-Lopez is being held even though a county judge found his birth certificate “authentic” and said there wasn’t reason to consider him an “illegal alien.”
