When a levee breaks water is free to flow through the breach and onto otherwise dry land. There are multiple ways of simulating a breach in a levee.
This scenario assumes the water body from which water will flow through the levee is located in the project area in its entirety.
Steps
The use-case can be implemented through the following steps.
How to visualize a breach:
- Add a Flooding Overlay.
- Configure the Overlay with a basic hydrological system.
- Add a result type of type SURFACE_LAST_VALUE to the Overlay (if the result type is not present yet).
- Either manually add a breach to the project, or import a breach.
- Ensure the overlay is (re)calculated.
- Inspect the "Surface last value" result overlay.
- Select the "play" option in the overlay's legend. The animation will show the flow of the water from the breach.
Notes
Multiple breaches can be added to the same project.
