We ran Alex's SWMM 4 data set through the new Beta B version of the SWMM 5 Converter and SWMM 5 program and there was complete agreement between the SWMM 4 and 5 results. As stated earlier, we will post Beta B on the EPA SWMM website sometime next week (when our webmaster returns to the office). Sorry for all of the problems encountered with Beta A, although that's made it a very rewarding beta test period for the SWMM 5 development team so far. We hope more of you will try out the program once Beta B is posted.
