I reviewed your model and found that the subbasin was not connected to an outlet junction. In addition, the junction maximum (rim) elevation was defined equal to the junction invert elevation. In addition, you had a detention pond curve defined but there was no detention pond and so I deleted the detention pond curve. I was able to run the revised model (attached) for the 50 year storm and now there is flow in the ditch.
See the attached (revised) model.
