Visualize levee breach from water body inside project area use case (Water Overlay)
Revision as of 09:12, 15 April 2019 by Rudolf@tygron.nl (talk | contribs)
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.
Requirements
Before implementing this use-case, make sure you have a basic water model set up. For the specified scenario, the flooding overlay is required.
Also ensure the following in your project, if possible:
- The hydrological system has a SURFACE_LAST_VALUE or 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.
Steps
The use-case can be implemented through the following steps.
How to visualize a breach:
- Add a Flooding Overlay.
- Configure the Flooding overlay with a basic hydrological system.
- Add a result type of type SURFACE_LAST_VALUE to the Water Overlay.
- Add a breach to the project.
- 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.
