Hello all, What are the big differences when it comes to modeling culverts vs. bridges in HEC RAS. I browsed the Army Corps manual and did not pick any. What am I really missing? thanks
In the past I have designated a fence as if it were a guardrail. These fences have been a continuation of the guardrail in place. This particular fence cannot be considered a guardrail as it is not a part of the structure. The bottom of the fence is suspended above the stream channel. It...

I have ineffective areas shown on certain cross sections for my 100 yr boundaries. Would this need to be included while drafting the 100 year floodplain?
