Thank you for your responses to the Major/Minor Drainage question, we are progressing very well.

I am now trying to determine the theory behind the ORFULL SWMM Configuration parameter.

I purchased the SWMM Workshop Notes which outline the various modules presently offered by SWMM. ORFULL was referred to in one of these modules, but I've been unable to find additional information about it. I would like to know how it works

any suggestions?
