|message_desc=Cross-Sectional data for the channel named "XXXX" cannot be found.

|suggestions=Each channel requires a table describing its hydraulic properties to define its conveyance. The properties are normally defined by digitising a cross-section in a 1d_xs or 1d_tab layer positioned midway along the channel or at the channel ends. If the cross-section is applied at channel ends, the cross-section lines must have a mid-vertex snapped to the channel end. If the cross-section is positioned midway along the channel, it must have either:

* In case of more than two vertices, one must be snapped onto a 1D network vertex.

The 1d_xs or 1d_tab layer references an external csv file (or similar formatted file) containing either a cross-section profile or a hydraulic properties table. The hydraulic properties can also be externally sourced from a Mike 11 or Flood Modeller. Note that structures such as culverts and weirs, are an exception to the rule. The attribute information supplied within the 1d_nwk table are sufficient to define the hydraulic properties. <br>
