HEC-RAS Boundary Condition Question for BFE Determination
HEC-RAS Boundary Condition Question for BFE Determination
(OP)
I'm modeling a stream with HEC-RAS that ties into a studied river with established BFE's. I'm trying to establish a BFE on a residential lot adjacent to the stream. My area of interest along the stream is only about a 1/2 mile upstream from the junction with the river. Am I correct in assuming my known water surface elevation downstream is the BFE for the river at the junction, and then using that for my downstream boundary reach condition on my stream?
Or do I just need to ignore the BFE of the river and set my downstream boundary condition of the stream to normal depth since they won't both peak at the same time?
Thanks for any suggestions!
