Difference between storm sewer pipe and a culvert pipe
Difference between storm sewer pipe and a culvert pipe
(OP)
I am trying to understand the difference between storm sewer pipe that is designed by Mannings equation vs culvert design. Why can't we size a culvert using Mannings equation, considering that it is conveying flow from one end to other?
Can someone explain?

you also need to factor in the tailwater and entrance losses. for a "short" culvert, these are highly critical and may totally override the normal depth. so most culvert capacities are a function of the inlet or outlet conditions.

Culverts are typically short as cvg points out and experience more rapidly changing flow regimes.
Hopes this helps.
