|type=[[CHECK]]
|message_desc=Lowered SX ZC Zpt to 1D node bed level. This message only appears in the _message.mif file and is associated with a special 2D cell style (<u>wjs??? - in the description from the access database, there was a ??? here, was this on purpose</u>).<br>
A "Z" flag has been used ato adjust the ZC elevation at each cell at/along the 2D SX object to below the 1D node bed elevation where ZC is higher. The ZC elevation is set to the Cell Wet/Dry Depth below the 1D node bed. It is not recommended to use the Z flag without first checking that the reason for the discrepancy in elevations between 1D and 2D domains is appropriate.<br>
The "Z" flag lowers only the cell centre (ZC) and if used inappropriately can result in stability issues if there is a discrepancy between 1D node and surrounding 2D elevations.<br>
|suggestions=Check elevation at 1D node and 2D cells, if a large discrepancy exists, review levels. For example a 1D pit with an elevation (from survey) maybe significantly below the elevation in the DEM. Using a SX connection with a Z flag will lower the cell centre to below the 1D level, but will not lower a flow-path into pit and may cause stability issues.
