==Requirements==
Before implementing this use-case, make sure you have a [[Basic water model use case (Water Overlay)|basic water model]] set up. For the specified scenario, the [[Flooding_(Overlay)|flooding overlay]] is required.
Also ensure the following in your project, if possible:
* The hydrological system has a [[Surface last value result type (Water Overlay)|SURFACE_LAST_VALUE]] or [[Waterstress result type (Water Overlay)|WATER_STRESS]] result type, either as main result or as a child result type.
* The simulation is set up to output a reasonable amount of timeframes. For a stabilization case, one timeframe per 12 hours of simulation time is reasonable.

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/completed through the following steps.

How to visualize a breach:
  1. Add a Flooding Overlay.
  2. Configure the Overlay with a basic hydrological system.
  3. Add a Result type of type 'Surface last value' to the Overlay (if the result type was not yet present).
  4. Either manually add a breach and input area to the project, or import a breach and input area.
  5. Ensure the Overlay is (re)calculated.
  6. Inspect the 'Surface last value' result.
  7. 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, by repeating the step for adding breaches to the project.
