You guys got to it before I did. Both stream and river will most definitely NOT peak at the same time. My big hangup was trying to figure out what kind of backwater effect the main river was going to have on my stream. I'll be sure to cut enough cross sections and test a couple different...
Thanks for the help. Yes, I can cut a section right where my stream hits the river with the established BFE's. I guess for clarification, do I want to use the 100 year BFE as my known downstream WSE when I run a 100 year flow thru my stream model, or do I need to find the normal WSE?
Thanks again.
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...
