=Introduction=
Open waterways (channels) are most commonly modelled as "S" type channels, the S signifies a sloping channel that can handle steep, super-critical flows. Open channels can either be modeled as an inertial or non-inertial channel, the latter removes the Courant stability condition and is useful for stabilizing very short S channels with high velocities.<br>

Ideally the location of the HX polyline, that represents the 1D/2D boundary, should be situated along the bank of the open channel. This is covered more in
