To simulate a scenario such as a flood wave in a river, you can create inlet and outlet areas. These are essentially breach areas; the inlet area represents the inflow of water, while the outlet area represents the outflow. The images show an example with invented values for the attributes.
How to set up a flood wave scenario:
- Draw two areas, one at one side of the river where the water will flow in and one at the other side of the river where the water flows out. It is also possible to import a GeoJSON file with these areas.
- The areas should have a breach floor attribute. Give the inlet area an outlet level and/or outlet Q. This depends on the available scenario data. If you know the water level of a flood wave, use the outlet level; if you know the flow rate, use the outlet Q. Using both is possible, in which case the outlet level takes precedence over the outlet Q. For the outlet area, enter a negative outlet Q value and/or an outlet level.
- Add a Flooding Overlay and go to the 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, check if the attributes of the areas correspond with what you have set as attributes.
- In step 2.2 import your water level areas with at least a water level attribute.
- Finish the Wizard and refresh the Overlay.
- After the flooding is calculated, check the Water Balance to get more insight in the scenario.
