Hi there,
While the NITs from South India have always had an edge over the north Indian ones in term of placements, research, facilities, etc.
but Some North Indian NITs are also equally comparable to them.
For pursuing an MTech in Civil Engineering, I would like to recommend you the following order 
1) MNNIT, Allahabad
2) MNIT, Jaipur
3) MANIT, Bhopal
4) NIT Kurukshetra
5) SVNIT, Surat
6) Dr B R Ambedkar NIT, Jalandhar
7) NIT, Hamirpur
