1D Open Channels
Page Under Construction
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.
