This page describes several use cases and examples of configurations in the Flooding Overlay.

Time-controlled flow rate in Breach

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 units. This can be in seconds, minutes, hours or days.
  3. Add the corresponding flow rates per unit 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 Add.
  7. Import your CSV file.
  8. Select your time units.
