Aggregation settings

You can set multiple aggregation options for each flow_variable as long as the aggregation_method is not used twice for the same flow_variable.

Columns

var_name

A user-defined variable name to distinguish between aggregated configuration of variables for user administration only. This setting is mandatory.

flow_variable

The different flow variable for which to determine aggregated results are. The flow variables for input to generate aggregated results are:

  • waterlevel

  • flow_velocity

  • discharge

  • volume

  • pump_discharge

  • wet_cross-section

  • lateral_discharge

  • wet_surface

  • rain

  • simple_infiltration

  • leakage

  • interception

  • surface_source_sink_discharge

aggregation_method

The different aggregation methods that can be used on a flow variable are:

  • max: maximum value of the variable in the configured interval (time step).

  • min: minimum value of the variable in the configured interval (time step).

  • avg: average value of the variable in the configured interval (time step).

  • cum: This is integration over time of the variable [dt * variable]. For instance, the cumulative net discharge across a flow line in the configured interval.

  • cum_positive: This is integration over time of the variable [dt * variable] in positive direction. For instance, the cumulative net discharge in positive direction across a flow line in the configured interval.

  • cum_negative: This is integration over time of the variable [dt * variable] in negative direction. For instance, the cumulative net discharge in negative direction across a flow line in the configured interval.

  • current: Uses the current value of a variable. This is required in case one checks the water balance for variables that are the result of the processes. This is a setting only valid for volume and intercepted_volume.

time_step

Time step is the interval in seconds for writing and determining the aggregated flow results. In the example above, the maximum water level is determined over every 600 seconds. The minimum water level is determined over a period ov 500 seconds.
