I am modeling several detention ponds and am curious to know which approach is better for modeling the outlets for these ponds.

I am using the EXTRAN block and have used orifices for the outlets and actual conduits for the outlets. I get results that are similar to each other, but not close enough.

I would like guidance on which method is the best to use and what the computational differences are between the two methods.

Thanks in advance.
