Hi aspirant

Environmental engineering is a interdisciplinary branch of Civil Engineering .In order to take admission in Environmental engineering you need to qualify GATE with valid score in Civil engineering .

It will be quiet difficult for a EE candidate to switch to CE .Though it is possible but very tough for any one because of different papers throughout your semesters.

So choose wisely in which stream you wish to opt M.tech and prepare accordingly.
