This page describes several use cases and examples of configurations in the [[Flooding_(Overlay)|Flooding Overlay]].
This page describes how to realize specific use cases by using the [[Water Module|water module]].


==Time-controlled flow rate in Breach==
==Water system model==
To create a variable Outlet Q in a breach area, a CSV (comma-separated values) file can be imported.
* [[How to import a GeoTIFF of waterway depths]]
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_add_Subsidence_(Water_Overlay)|Add subsidence calculation results to a water system's input]]
{{Editor steps|title= set-up your CSV in Excel
|Open Excel.
|In the first column, define your time units. This can be in seconds, minutes, hours or days.
|Add the corresponding flow rates per unit 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_Overlays#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.

==Multi Breach simulation==
==Flooding==
These configurations can be implemented best using the [[Flooding (Overlay)|Flooding Overlay]].
* [[Visualize levee breach from water body inside project area use case (Water Overlay)|Visualize levee breach from water body inside project area (river, small lake)]]
* [[Visualize levee breach from water body outside project area use case (Water Overlay)|Visualize levee breach with water from outside the project area (large lake, sea)]]
* [[Flood_wave_use_case_(Water_Overlay)|Create a flood wave across a river]]
<!--===Rain===
These configurations can be implemented best using the [[Rainfall (Overlay)|Rainfall Overlay]].
* [[Rain_in_project_area_use_case_(Water_Overlay)|Rain falling in the project area]]-->
 
==Water shortage==
These configurations can be implemented best using the [[Groundwater (Overlay)|Groundwater Overlay]].
* [[Drought_excessive_drain_use_case_(Water_Overlay)|Drought from excessive drains in the project area]]
* [[Drought_excessive_evaporation_use_case_(Water_Overlay)|Drought from excessive evaporation in the project area]]
 
==Water quality==
* [[How to trace water through project area (Water Overlay)|How to trace water flow in a hydrological system over time]]
 
==Stationary analyses==
* [[Calculate_stable_water_level_use_case_(Water_Overlay)|Manually calculate at what level the water level is stable]]
