How to import a breach with an external 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 has the external area, external water level, and external surface level attributes for the breach feature.
  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. The configuration wizard of the Flooding Overlay can now be closed.

Notes

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