=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>

=Basic Commands=
Within the *.ecf the following commands and files are at a minimum required to a model an open channel:<br>

<font color="blue"><tt>Read GIS Network</tt></font> <font color="red"><tt>==</tt></font><tt>..\model\mi\1d_nwke_xxxxx.MIF</tt><br> ! network layer containing "S" channel alignments
<font color="blue"><tt>Read GIS Table Links</tt></font> <font color="red"><tt>==</tt></font><tt>..\model\mi\1d_xs_xxxxx.MIF</tt><br> ! corresponding cross-section polylines
