Typically these smaller buried. Culvert hydrology and hydraulic calculations as described in Section 3-3 and Table 3-2. Examples of flexible pipes are plastic and thin walled metal pipes.

Box culvert is a rectangular shape reinforced concrete structure consists of single or multiple boxes allowing movement of water and traffic. The correlation between the design equations and the design nomographs is not exact. The emphasis in this Chapter is on the design of culverts for urban stormwater drainage.

Highway authorities may have different or additional requirements which are not discussed herein. The proof is in the pictures of this brochure that show jetting or collapse of high density polyethylene culverts and the roadways because of flotation. 2500 package of 25.

Culvert Extension - A portion of a culvert built beyond the limits of a previously existing culvert. Major design parameters for culvert design are the diameter and slope of the pipe for a specified culvert material. Cast-in-place reinforced concrete box culverts have been designed and used for many years because of special waterway requirements unusual load conditions or designer preference.
