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;
