I am using the Hydraflow Storm Sewers Extension 2012 and I keep getting different Q's at the outfall depending on the calclulation option I choose. It seems like I need to toggle "Analysis w/Design" and then toggle "Reset Pipe Sizes" to get the system outfall Q. If I only toggle "Analysis w/ Design" the Q drops drastically. Does anyone know the proper Calculation option to get a system Q at the outfall for a given event if you only want to analyze the system without making changes? Thanks!!

Do you have any surcharged structures? The flow will pond at that point until it can continue to flow through the system reducing your max Q.
Alternatively, that flow might be lost from the system, off the top of my head, I can't remember which.
