0.00 CFS COMING INTO MY CATCH BASINS
(OP)
Hello! Can anyone tell me why this model is not allowing water to pass through the catch basin grates during the 50 year storm? Is this a tailwater issue? I posted the file below
Thanks!
Thanks!

Also - CB1 numbers are suspect as the grate is below the crown of the outlet pipe.

Short answer: Delete the grate. (Device #3) The grate is not an outlet device on the CB, so it shouldn't be used to limit flow to the culvert.
This will allow water to exit freely through the culvert -or- overflow through your secondary outflow.
For details please see www.hydrocad.net/sewers.htm Note the section entitled "What about the grate?"
