Culvert Headwater
Culvert Headwater
(OP)
if there are two consecutive culverts about 50 m apart how could the headwater of the second culvert affect the tailwater of the first. Does the backwater formed at the inlet of the second affect the flow regime of the first. another question about the headwater level to what distance it can extend transversally





RE: Culvert Headwater
One would need to analyze the entire scenario.
RE: Culvert Headwater
Really, though, this shouldn't be a problem, because if the pipes are 50m apart, you're not getting much additional flow to the second pipe and it'll only have to deal with the water coming out of the first. As long as the pipes are the same size, or the downstream one is bigger, and there's no significant change in flow, then you should be fine between pipes, but may have headwater issues upstream.

Shouldnt take much time but after you run it, you can see the water profile, sub-critical/super-critical changes etc.
Run the model with and without the second culvert, and see if the tail water depth for the first culvert changes.
