Most Delft-FEWS systems nowadays use the topology.xml to configure the work process of the forecaster in the IFD-environment. The topology.xml is a mandatory configuration file when you are setting up an IFD-environment (Interactive Forecasting Display). The topology.xml is used to configure the behavior of the forecast panel. This will be explained in more detail in the next sections.
TopologyGroup.xml
It is possible to split the configuration of the topology in separate configuration files.
The main configuration file is always the topology.xml. The other (supporting) configuration files are the topology group files. The topology group files should be placed in the RegionConfigfiles folder. The name of a topology group file should start with TopologyGroup.
An example of a topology group file is shown below.

The defined topology groups can be used in the topology.xml by using the element <groupId>. An example is shown below.

<nodes id="InflowForecast" name="Inflow Forecast">
<warmState unit="day" multiplier="11"/>
<groupId>ForecastGroup_Bear</groupId> |
