Enter '''-99999''' in the ''Value:'' box. Click 'OK' and you should see that the eight points in the browser table now show -99,999 as their Z attribute.

===Create the 2D Layered Flow Constriction===

The following steps are used to create the 2D layered flow constriction - ''2d_lfsch'' - that will represent the bridge in the 2D domain. The flow constriction layers provided here are mostly completed. If these were not provided, the method would be to import the "2d_lfsch_empty.mif" and "2d_lfsch_empty_pts.mif" files from the TUFLOW\model\mi\empty folder and save them in the TUFLOW\model\mi\ folder, renaming the files and beginning the edits in these new layers.<br>

<li> The above edits and layers result in the below bridge configuration:
