I have looked through help and SSA. I am looking for where the multiplier for 100-year rational runoff coefficients may be applied. Typically, for 25-yr return period, the C value should be multiplied by 1.1, for 50-yr multiplied by 1.2, for 100-yr, multiplied by 1.25.
Does SSA automatically do this or is there a setting somewhere to apply these multipliers?
Thanks!

We are in a similar situation where I am, our regulations have a table that gives a C value for a 5-year winter storm and both 100-year storm values based on the design C value. The only solution I have found is to have 4 different design files.
Not the answer I am sure you have been looking for but the only option as of right now.
I also have to do separate files. It seems that it is something that could be incorporated into SSA relatively easily. Maybe next year's version!
