|message_desc=Lowered SX ZC Zpt to 1D node bed level
A "Z" flag has been used to 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>
Line 10:
The message switches from a CHECK to a WARNING at 0.3m (or 1 ft if using English Units) to draw further attention to large changes that may indicate potential erroneous inconsistency between the pit/channel level and the ZC ground level.<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. To lower flow path into the pit, Z shape polygon can be used.
