Add Discharge Section

A Discharge Section in RS3 is a user-defined surface through which the volumetric flow rate of groundwater will be calculated during a groundwater seepage analysis.

• Discharge Sections can only be defined if the Groundwater Method = Steady State or Transient Finite Element Analysis in Project Settings.
• The value of the flow rate will be displayed when you view the analysis results.

Add Discharge Section

To add a Discharge Section:

1. Select the Groundwater workflow tab
2. Ensure that you have at least one surface geometry you wish to convert to a discharge section. Note: After you have added a discharge section, you cannot edit the geometry or location without deleting the discharge section first.
3. Select Entity Selection as the Selection Mode to add surface geometries to generate the discharge section.
4. Select at least one surface geometry to generate a discharge section. If you select multiple surfaces, multiple discharge sections will be generated.
5. Select Add Discharge Section from the toolbar or the Groundwater menu.

The Discharge Section is displayed as a green surface in the model viewport. In the Visibility pane the selected surfaces should be converted to discharge sections with the type beside the name and a green colour.
