Normal Depth Downstream Boundary Condition Unsteady Flow Simulation

Recommended Posts

Is there a way to set the downstream boundary condition to calculate a Normal Depth solution for an unsteady flow simulation? I saw the option to do so for Constant Flow, but not for a unsteady simulation. 

Thanks,

Jeremy

Jeremy,

  The recommended method for do that is to use a rating curve.  You can use the populate tool to compute a level for any flow in the expected range of flows that will occur during a hydrograph. 

  This avoids needed to worry about latency and attenuation of the flow from the inflow to the outflow.
