Lateral Outflow Modelling

[prolific]

I am new to HEC-RAS.

I have a canal with 8 bridges and I want to model it using unsteady state approach.
The upstream boundary is constant flow hydrograph and downstream boundary is a stage hydrograph.
I want the entire flow from the upstream to exit the system through a lateral connection before reaching downstream boundary.

After simulation, When I run the animation of profile plot the flow passes directly to downstream. I just want to exit the system through lateral outflow location, not flow to downstream boundary condition.

How can I do that?

Thank you for your help!

You can define one or more lateral flow hydrographs. If you enter negative numbers it will remove flow.

If the lateral outflow hydrographs remove the same amount of flow as the upstream hydrograph, then once things settle down the downstream boundary should have zero flow.
