Message Type
WARNING

Description
The model being simulated contains one or more rainfall boundaries and the cell wet/dry depth is set to a value greater than 0.0002m. The default value as of Build 2006-03-AB, is 0.002m (2mm).

Suggestions
The depth specified should be selected in accordance with the expected magnitude of flooding depths. For direct rainfall models, due to the substantial amounts of shallow sheet flow, it is recommended to reduce the depth to 0.0002 (0.2mm) by using the TCF command Cell Wet/Dry Depth == 0.0002. Using a cell wet/dry depth greater than 0.0002m may result in the model experiencing high mass errors.
