Check Files 2d vzsh
This GIS check file layer is only written if a variable Z shape object (2d_vzsh) is used in the model. vzsh_zpt_check contains information on the elevation points that may change over time, the elevation change, final elevation as well as the trigger conditions.
Note that if using a variable Z shape, the map output type "zh" can be included in the Map Output Data Type == command to write the elevations over time. For example, the following command would output water levels (h), velocities (v), depths (d) and elevations (zh):
Map Output Data Type == h v d zh

| dZ | The change in elevation that will be caused by the variable Z shape. A negative value indicates the elevation will decrease and a positive value indicates the elevation will increase. |
| Final_Z | The final elevation after variable elevation has been triggered. |
| Type | Whether the variable Z shape is applying as a point or side. |
| Period | The number of hours over which the elevation change will occur. |
| When | A text description of when the change will start. For example "Water level at [138;76] exceeds 41.". |
