Boundary Conditions in SWMM 4
For the sake of completeness and posterity I am including in this email an example SWMM 4.x Extran model that has all 7 possible boundary conditions for the outfalls. As Khalid mentions the value of NBCF on the I1 line determines which set of J lines is used for the outfall listed in the first column of line I1. The set of J1 lines is independent of the order of outfalls on the I1 lines. For example, I could have had the outfall using boundaries conditions 7 down to 1 instead of 1 to 7 - as long as the J lines are in the correct order.EXAM43.DAT
