failing an earthen dam in my model. the geometry includes road culverts and bridges (as SA connections). for some SA connections, why would the flow hydrograph go to negative value? Below are screen captions of the geometry. I set the 4 ft diam CMP to Solution criteria (Highest US EG).

backwater effects? From what is shows, the discharge is going upstream through the structure.
