How do I restrict flow only on the main channel for low flow condition without a leeve? It seems "Bank" is used just for "n" value. Shouldn't the bank station recieve any flow if the main channel overtops? Please help

You seem to have an interesting condition in that your water cascades down an embankment and is actually lost from your system if it overtops the channel. Is this a diversion ditch at the top of an embankment and you're calculating the 100-year flow in the ditch to make sure it doesn't overtop? If that's the case, I wouldn't even bother including the retaining wall in the model and just stopping the x-section at the top of the retaining wall. HEC-RAS will throw an error message if your flow goes higher than the limit of the x-section.

A bulding pad is proposed at the bottom of the wall.
what is the recommended value for riprap? any idea.
Thanks
