I used to be  a civil engineering student, before changing my major, and I can tell you the best way to figure out which major is right for you is by shooting an email to the specific departments you are interested in. I know the academic advisors for civil engineering were really helpful with me when I was trying to pick a major, and I would imagine they would be more than willing to help you out as well. I'd just say look up their contact information on their respective wesbites and see if you can get a hold of someone that way!
