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.
Example of an open channel that could be modelled in 1D
Basic Commands
Within the *.ecf the following commands and files are at a minimum required to a model an open channel:
Read GIS Network ==..\model\mi\1d_nwke_xxxxx.MIF ! network layer containing "S" channel alignments
Read GIS Table Links ==..\model\mi\1d_xs_xxxxx.MIF ! corresponding cross-section polylines
The tutorial model here runs through the necessary layers and setup for a 1D open channel within a model.

Typical check files used
The table below highlights some of the commonly used check files when reviewing 1D open channels. The full list of TUFLOW check files can be found here.
