Need HEC-HMS Assistance

[Jessica2424]

I am pretty new to HEC-HMS and I seem to be having many problems with it. I am trying to model a watershed of about 1700 acres. There are many basins, ditches and culverts in my watershed. I am having a huge problem modeling the culverts. Can I model culverts in HEC-HMS or should I leave them out of HMS and input them into HEC-RAS? Any ideas? If I should include them in HEC-HMS, then how should I model them?
