The window <Waterway performance> has been opened
offering an overview of the behaviour of the waterway during the load rejection.
At the time this window was "frozen", the level in the <Brook intake> is 395.91 m.
and the flow of water is –1.91 m3/sec.
causing decreasing Level.

Steady state details before load rejection.
<Waterway performance> may be opened from <Workbench>
but only for steady state operation.
In this case openings, strokes, levels etc. must be set in this window directly.
