TUFLOW Message 2472

TUFLOW Message
WARNING 2472 - Grid interpolation happens at the edge of DEM.

Alternate Message
WARNING 2472 - Grid interpolation includes Null value.

Message Type
WARNING

Description

This could occur if:

1. The input grid has an extent less than the model domain (can be reviewed using the dom_check), therefore the SGS interpolation will occur at the edge of the DEM. This message is only reported if "Verbose == ON" is used.
2. There are NULL values within the raster.

Suggestions
Review the input DEM, to check if there are NULL values in the raster. If the warning is due to the DEM extent being within the 2D domain, no action is required.
