Critical depth in Extran

Dear Swmmers,

Using Extran swmm4.4, if I set a free Outfall for a boundary condition,
will the flow go out of system trough the critical depth?

Thanks in advance.

Giovanni - you have to instruct EXTRAN what profile you want at the
exit. See the EXTRAN.DOC instructions for the BB input line. Select
JDOWN = 0,1, or 2. For critical depth at free outfalls, set JDOWN=1.

Good luck
