This page describes several use cases and examples of configurations in the Flooding Overlay.
Time-controlled flow rate in a Breach area
To create a variable Outlet Q in a breach area, a CSV (comma-separated values) file can be imported. Below the steps on how to create such a breach area. For this example we create the CSV in Excel, but you can also use another program to create the CSV.
How to set-up your CSV in Excel:
- Open Excel.
- In the first column, define your time steps. This can be in seconds, minutes, hours or days.
- Add the corresponding flow rates per step in the second column.
- Save the Excel as a CSV.
How to import the CSV as the flow rate:
- Either add a breach area or have your GeoJSON file with your breach area ready. The area should have at least a breach floor attribute.
- Add a Flooding Overlay.
- Go to the Configuration Wizard of the Flooding Overlay.
- In step 2.1 either select the attribute that specifies your breach_floor or import your GeoJSON file.
- Click on Next.
- In the dropdown menu, select your breach area. Now click on Edit.
- Import your CSV file by selecting the CSV file.
- Select the time units in your file.
- Select the seperator for your file.
- Click on Apply.
Multi breach simulation
It is also possible to simulate a situation in where there is first one dike breach, following by another (or multiple). Therefore we also make use of the variable Outlet Q as mentioned above in the previous use case. In the steps below, two breaches are demonstrated, but the same steps apply to multiple breaches.
How to set up a multi breach scenario:
- Either add two breach areas or have your GeoJSON file with your breach areas ready. The areas should have at least a breach floor attribute.
- Add a Flooding Overlay.
- Go to the Configuration Wizard of the Flooding Overlay.
- In step 2.1 either select the attribute that specifies your breach floor or import your GeoJSON file.
- Click on Next.
- In the dropdown menu, select the breach area that breaks second.
- Click on Edit and import the CSV file. Structure the data in the CSV in a way that at the start of the simulation, the outlet is 0.
- Finish the Wizard and refresh the Overlay.
