Good Day,
I have a HEC-RAS model of a reach of a river and have completed the whole analysis including a reasonable floodway delineation.
My problem is the FEMA contractor reviewing my study wants me to include as encroachment the high ground (above bfe) between the encroachment limits
defining the flood way.
This is a new one on me and I don't understand the need for it to begin with.
Can anyone tell me if this is customary for HEC-RAS 4.1 (yes I've been at this a while) and if so do I just delineate the high ground with isolated encroachments?
Thanks.
Ron Rice
