When the head losses in a culvert are critical, the PEO may consider the use of a hydraulically improved inlet.
Buried structures greater than 10 feet long require wing walls. Wing walls and aprons are required with reinforced concrete box
A headwall is a concrete frame poured around a beveled culvert end. It provides structural support to the culvert, eliminates
A metal flared end section is a manufactured culvert end that provides a simple transition from culvert to channel. Flared
A mitered end treatment consisting of cutting the end of the culvert at an angle to match the embankment slope
A projecting end is a treatment where the culvert is allowed to protrude out of the embankment (see Figure 3-4).
The type of end treatment used on a culvert depends on many interrelated and sometimes conflicting considerations. The PEO must
Once familiar with culvert design theory as presented in this chapter, the PEO shall use one of several commercially available
