Hi

If u are concerned about the branch options then , both the branches are good in their own sense. On one hand mechanical engineering is an evergreen branch and even still enjoys a good scope in various prospects.

Mechanical engineering, the broadest of all Engineering disciplines deals with design and production of tools, machines and all other mechanical equipment to be used in industries. The industry offers a wide choice of options extending across many interdisciplinary interdependent specialties.Mechanical Engineering finds applications in all fields of technology. They could work in many industries including private or public sector industries of various types, and their work varies by industry and function. With the rapid rate of expansion in the industrial sector, the employment potential for mechanical engineers is very high. 

On the other hand civil engineering is something that is growing at a very good pace at present in India especially, where infrs development is taking place at such a fast pace.
