TUFLOW Message 1123

TUFLOW Message
ERROR 1123 - More than one cross-section line of same priority for channel

Alternate Message
NA

Message Type
ERROR

Description
Multiple cross-sections with the same priority have been found for channel. Mid channel cross-sections have higher priority than end cross-sections and will prevail. But if multiple mid channel cross-sections are found TUFLOW will give Error 1123.

Suggestions
Check channel and cross-section configuration, remove unwanted cross-section.
If using end cross-sections ensure that the end of the 1d_nwk layer is snapped to a vertex on the cross-section. If this is not the case the cross-section may be treated as a mid cross-section. An example of where this may occur is shown in the schematic below.
