Thank you Mitchell for you help. I was able to run the model and achieve the desired results. Can you recommend any Fortran references to learn more about how to set up variable like the FIRMAT, the SWMM manual is lacking in this area?

Rob, I am having trouble sending you email directly. Please send me an email off the list to review the method of bringing the rainfall data in through PCSWMM.
