==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.
{{Editor steps|title= 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.

{{Editor steps|title= 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 [[Flooding_(Overlay)#Define_a_Breach_area|breach floor attribute]].
|Add a [[Flooding_(Overlay)|Flooding Overlay]].
|Go to the [[Water_Overlay#Configuration_Wizard|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.
