WARNING 10058 - It is recommended to use Sigma 3D vertical layering (not Z or Z-Sigma) when sediment morphologic update is enabled.

Description

This warning is raised when sediment morphologic update is enabled alongside Z or Z-Sigma vertical layering. Sigma 3D layering is the recommended vertical discretisation for models with an active bed morphology.

Suggestions

In the model control file, use Vertical Mesh Type == Sigma to enable Sigma 3D vertical layering.
