Hydrologic & hydraulic considerations for planning and design of culverts for road drainage

Several new road Schemes as well as up-gradation of existing roads are being undertaken by the Government of India for better and faster communication amongst the different parts of the country. Drainage of road is an important aspect of road project for the purposes of safety, speed, maintenance and life span of the road. Design of culverts which is an integral part of any road drainage scheme is to be done scientifically for efficient functioning. The paper outlines the various data to be collected from different sources for proper planning and design of culverts and deciding their location, type and size for new roads as well for up-gradation of existing ones. Different hydrological and hydraulic considerations including use of software involved in the design of culverts have been discussed at length.
