Encroachment in Hec_Ras
(OP)
I had a FEMA model with encroachment analysis. I added few surveyed cross-sections into this model. And, when I tried to run the encroached model, the 'RUN' stopped at my added station saying ' encroachment at this station blocks out the cross-section'. What is the issue on it, if anyone has any idea on it. Will appreciate.

Try plotting the cross sections or sections which are creating the error message and posting them here. That may give you the answer or provide enough information so that others may be able to help.
RE: Encroachment in Hec_Ras
there's a possibility that the values in the encroachment table don't match the stationing of the cross-section. e.g. your encroachment may have been based on a section starting at station 1000 but now your cross section starts at station 0.

Thanks for helping me out..

"You might want to post your site plan with cross sections and maybe the RAS report too."
This is becoming less and less clear. Are you trying to do an encroachment analysis OR are you trying to analyze a bridge replacement ? The two are not identical problems.
