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.<br>
Note that if using a variable Z shape, the map output type "zh" can be included in the <tt><font color="blue">Map Output Data Type </font><font color="red">== </font></tt> command to write the elevations over time. For example, the following command would output water levels (h), velocities (v), depths (d) and elevations (zh): <br>
<tt><font color="blue">Map Output Data Type </font><font color="red">== </font> h v d zh</tt><br>
