The effects of rivers, intakes and outlets from power stations etc. can be included in a simulation. These sources and sinks are included in the hydrodynamic equations in the following way:
· If your source or sink has a magnitude of Q m3/s, then the additional term on the right hand side of the continuity equation is
· If, for sources, you specify a speed of V m/s in direction q, then the additional term on the right hand side of the momentum equations are
where qNYC is the orientation of the model (see Orientation (p. 116)).
