Bob,
I have similar situation where I have received pdf copy of HEC-2 model print out. I need to re-create HEC-RAS model for limited portion of area from pdf printout.
You mentioned that you have a spreadsheet program that helps doing just that. I would be interested in it if it is ok with you.
Also, how do you taking in account of meandering of stream within study area when building model from HEC-2 print out to HEC-RAS.
Thanks,
Paresh
