Culvert Capacity... in HEC-RAS model

[mahey07]

Hello guys,

Just a quick question, I am running HEC-RAS for different design storms (2 Year to 100 year).

Question is: Does the HEC-RAS model gives the culvert capacity as output? Or, does it just compute the culvert flow ("Q") for those design flows? BY CULVERT CAPACITY, I mean - maximum flow possible through a culvert without any weir flow or road over-topping.

thanks!!

Not that I am aware of; I beleive it only provides culvert flows and weir flow.

yeah, that's what I thought. Thanks for confirming, Gbam!

You want HY8.
