    Hi all,

    I modeled 2 reaches into 1 reach. Junction is used to do this but for some reason, the flow is not transferring to the downstream reach (Steady Flow).

    The error message, “HEC-RAS Error – Incomplete data, the following errors were found:
    River: “Lower Main” Reach: “3” RS=150 – has an undefined flow value.” comes up which is suggesting flow is not transferring.

    I checked cross sections and the elevations line up. Also Inflow is defined at 2 upstream positions.

    Any ideas?

    Thanks.
