Please note: This page is currently being updated.

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:
  1. Open Excel.
  2. In the first column, define your time steps. This can be in seconds, minutes, hours or days.
  3. Add the corresponding flow rates per step in the second column.
  4. Save the Excel as a CSV.
How to import the CSV as the flow rate:
  1. 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.
  2. Add a Flooding Overlay.
  3. Go to the Configuration Wizard of the Flooding Overlay.
  4. In step 2.1 either select the attribute that specifies your breach_floor or import your GeoJSON file.
  5. Click on Next.
  6. In the dropdown menu, select your breach area. Now click on Edit.
  7. Import your CSV file by selecting the CSV file.
  8. Select the time units in your file.
  9. Select the seperator for your file.
  10. Click on Apply.

Multi Breach simulation

It is also possible to simulate multiple breaches. Therefore we also make use of the variable Outlet Q as mentioned above in the previous use case.

How to setting up multiple breaches:
  1. Add two breaches by either adding them as areas or importing them.
  2. In the first column, define your time steps. This can be in seconds, minutes, hours or days.
  3. Add the corresponding flow rates per step in the second column.
  4. Save the Excel as a CSV.
