    Working with Conduit links


    Article summary

    Recall if using Steady or Kinematic Wave routing, only a single outflow Conduit link is allowed from a Junction node, however two Conduit links are allowed from a Flow-Divider node.

    The Conduit link Properties Window is shown below.

    Click in the Name field, type a new name and click the Enter key to adjust the label provided to your conduit. This is populated by default based on values set on the Model Defaults window, recall how to edit these defaults from the Urban Networks section.

    The Inlet Node and Outlet Node are automatically filled based on the node location in the map view.

    A Description and/or Tag can be optional provided. You may find tags helpful to group components together - this can be a way to categorise specific nodes. To edit these, click in relevant the field, type a new value, and click the Enter key.

    The Shape and Max. Depth are specified. By default, these are based on values set on the Model Defaults window, recall how to edit these defaults from the Urban Networks section. Click in the Shape field and then on the 3 dots that appear to the right of the field and the Cross-Section Editor window will open. In this window you can select a shape for your conduit, specify the maximum depth, and specify the number of barrels (identical, parallel pipes). The maximum depth specified here will automatically populate the Max. Depth field in the conduit properties window. This value can also be adjusted here by typing a new value and clicking the Enter key.

    The conduit Length and Roughness are required. Both of these will be set by default to the value set in the Model Defaults window. To edit the values, click in the relevant field, type a new value, and click the Enter key. Note that the Length will be automatically calculated from the length of the line drawn on the map if the default length is set to zero in the Model Defaults window. Recall how to edit these defaults from the Urban Networks section, however for this to apply to a Conduit link, you will need to redraw the link - the length is only calculated at the point of the link being drawn.

    The conduit link Additional Parameters can all be edited by clicking in relevant the field, typing a new value, and clicking the Enter key. These parameters include the Inlet Offset and Outlet Offset. Conduit links can have an offset specified at the inflow and outflow ends. This is the distance from the invert level of the inflow/outflow node. The value may be as a depth or elevation, as specified by the Offset convention set in the Model Defaults window. Please see the Urban Conduit Link section of the technical reference for further details on the parameters set here.

    A Flap Gate can also be specified so prevent backflow. This option will be set to NO by default. Click in the field to access a dropdown and change this to YES if required.

    A Culvert Code can be optionally provided. Note: The Culvert code number is used only for conduits that act as culverts and should be analysed for inlet control conditions using the FHWA HDS-5 method, please see the Urban Conduit Link section of the technical reference for further details.
