A breach can be imported for a water calculation when using the configuration wizard of a Flooding Overlay.

Editor → Current Situation (Ribbon tab) → Overlays (Ribbon bar) → The Flooding Overlay (Left panel)

How to import a breach with a breach input area for a Flooding Overlay:

  1. Prepare a GeoJSON file with the desired data for the breach, most importantly the breach height attribute.
  2. Ensure the GeoJSON file also contains the feature for the breach input area, and explicitly no value or a non-numeric value for its breach height attribute.
  3. Open the configuration wizard of the Flooding Overlay.
  4. Continue to the step concerning breaches.
  5. Select the 'import' option. This will open the Geo data wizard.
  6. Follow the steps in the Geo data wizard.
  7. When the Geo Data Wizard is completed and closed, the breach and the input area have been imported.
  8. Select the breach
  9. For the breach input area, select the (other) imported area.
  10. The configuration wizard of the Flooding Overlay can now be closed as well.


Breaches can also affect Water Overlays other than the Flooding Overlays.

Currently, it is only feasible to create a breach with an input area via the configuration wizard, requiring the Flooding Overlay specifically.
