	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>		Open waterways (channels) are most commonly modelled as "S" type channels, the S signifies a sloping channel that can handle steep, super-critical flows.

	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 the <u>[https://docs.tuflow.com/classic-hpc/manual/latest/ TUFLOW Manual]</u>. In situations where the Digital terrain model does not properly define the bank elevation it can be necessary to include ZP points that are snapped to the HX lines that work in the same way as variable z line modifications.
