TUFLOW Message
CHECK 3519: Using MIN or GULLY option in SGS model.
Alternate Message
NA
Message Type
CHECK
Description
If the DEM is fine enough, SGS can preserve the gully along the cells without using any gully line. In such case using a gully line may overestimate the width of the flow path as it makes the entire cell and face flat.
Suggestions
Check if "SGS Sample Distance" and resolution of the DEM is fine enough to capture the gully line without using topography modification.
