Action:

1. Select the wastewater structure with the i-button
1. Select in layer vw_tww_wastewater_structure the wastewater structure with the i-button

2. Select the wastewater nodes tab in the Feature Attributes window
2. Select the **Wastewater Nodes** tab in the Feature Attributes window

3. Select a hydr_geometry in the fk_hydr_geometry field or use the + button to create a new hydr_geometry.
or direct way: Select in layer vw_wastewater_node the node with the i-button

3. Expand the part ** additional attributes in special structures**

4. Enter a description in the hydr_geometry - Feature Attributes window. This name is also the name of the table in MikeUrban.
4. Select a hydr_geometry in the fk_hydr_geometry field or use the **+** button to create a new hydr_geometry.

5. Before you can create a hydr: geom_relation, the new record hydr_geometry must be saved: -> click OK

6. Go back to the hydr_geometry you just created with the button **switch to form view** in the field fk_hydr_geometry .
5. For a new record: Enter a description in the hydr_geometry - Feature Attributes window. This name is also the name of the table in MikeUrban/+.

7. With the **Add child object** button, you can now generate the records with which the hydr_geometry is defined analogously to the basin geometry of MikeUrban (H, As surface, Ac cross-sectional area).
6. With the **Add child object** button, you can now generate the records with which the hydr_geometry is defined analogously to the basin geometry of MikeUrban/+ (H, As surface, Ac cross-sectional area).

In the table view, the overview of the values is easier.

Note:

* The water depth is the value above the bottom level or the outlet. A hydr_geometry can thus be used for several wastewater structure if they are built similar.

* In the table view, the overview of the values is easier.
* Be aware to respect the rules in Mike (e.g. continuous encreasing cross_section_area)

* As long as the hydr_geometry record is not saved, you see in the Features Attribute window just the Obj_Id in brackets. After saving, you will see the identifier you have entered.
