Hi aspirant,

Civil engineering is the branch of engineering  that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewerage systems, pipelines, structural components of buildings, and railways.

In engineering the number of girls is comparatively low than boys. The average number depends on a particular college and differ from college to college.

Hope you understand. Wish you all the best.
