|message_desc=If using effective area, a relative resistance factor of 1.0 must occur at some point in the profile to indicate the primary sub-channel. If this is not included, grossly incorrect channel velocities can occur.
|suggestions=Update the cross-sections to indicate a primary sub-channel:
* In the 1D cross-section table link (1d_xs) layer, ensure at least one cross-section has the "Flag" attribute set to "'''R'''".
* Update the corresponding source table to contain a relative resistance factor of 1.0.
Refer to the <u>[https://docs.tuflow.com/classic-hpc/manual/latest/ TUFLOW Manual]</u> for more information on cross-sections.
