The following chapter will discuss the terms, equipment, and procedures for two ....Longitudinal profile levelling by traversing 11. You need to survey the same line AB, the centre-line of a water canal, for profile levelling. You will use a non-sighting level, such as the flexible tube water level see Section 5.3. Since you are using this kind of level, you will survey by traversing.
