We are modelling a lake that has a vertical outflow pipe, and wondering how to specify the boundary conditions for this in the boundary condition file.
The outflow is via a vertical pipe 2.5m diameter pipe. We have the elevation of the opening.
What are the correct boundary condition keywords to use here?
Should we use flow_bottom, and then set the bathymetry at that cell to the elevation of the pipe?
Or is there a better option?
