ERROR 11004 - VanRijn04 external model must be enabled in order to provide variable inputs into VanRijn04 bedrough/bedshear/settling/erosion/bedload model/s

Description

One or more sediment transport sub-models (bed roughness, bed shear, settling, erosion or bedload) have been set to vanRijn04 but the external model has not been set to vanRijn04. The external model must be enabled when any of these sub-models use vanRijn04 as it provides the shared variable inputs required across sub-models.

Suggestions

Add External Model == vanRijn04 to the sediment transport control file, or change the affected sub-model selections to a model that does not require the external vanRijn04 module.
