When setting up a breach for a Flooding Overlay, the intent is for water to flow through it. That water must come from a defined source, and flow through a specific location. Water flowing through a breach is governed by, among other factors, the water level on either side of the breach. To properly measure the water level on the inside of the breach (e.g. , on the "dry" side of a levee), a specific breach level area can be configured, to define the location where water levels are measured for the purpose of water flowing through the breach.
How to add a breach with a level area to a Flooding Overlay manually:
- Make sure you already have a breach area defined, either with an input area or a virtual external area.
- Add an Area to the project. This will be the breach level area.
- Draw the breach level area in the Project area, in the location where the water level should be measures for the breach flow calculations.
- Add an Attribute to the created Area, with the breach level area attribute name and a value of choice. The attribute will make it available to select. Make sure this area is not a breach area itself.
- Also give the area a name that is easy to identify.
- Open the Overlay's configuration wizard and continue to the step concerning Breach growth.
- For the breach level area, select the created level area.
- Click on show to verify this is the correct area.
- Continue with the wizard.
