Additional constant flow added to the total runoff Unit: [m3/s] Default: 0

Total area of catchment

Geometry of the catchment. This is a list of coordinates defining a closed polygon as the extent of the catchment.

Catchment name

The name is not unique, there may be several catchment models for one catchment, however all catchments with the same name should/must share the same catchment geometry.

The central point of the catchment. Used for e.g. finding the rain time series closest to this catchment.

End time of catchment simulation - the latest time for which the catchment can return data

True if evaporation is enabled, and an evaporation boundary has been defined.

If set to false the initial recover rate is used during dry periods. Default: False

Dry depth used for switching Horton's mode between dry and wet in Kinematic Wave model: when InfiltrationAfterRain == true In this case the switching to regeneration of infiltration capacity is controlled by a low limit of the water depth on the surface. (from ini file) Unit: [m] Default: 1e-6

True if infiltration shall occur also after rain Default: True

Recovery rate for initial loss capacity. The initial loss capacity is regenerated in dry periods by a linear recovery rate.

Used as constant evaporation, when evaporation is not defined explicitly. If evaporation is defined explicitly (see EvaporationFromTimeSeries), this is neglected.

For some catchment models it is only applied under dry conditions.

Unit: [m/s] Default: 0.00005 [m/hour]

Catchment model ID. Unique id.

Catchment model ID. Unique id.

Observed data. Used for creating calibration plots and for auto-calibration reference data.

Number of person equivalent in the catchment, used with catchment discharge source boundary

Snow melt coefficient. Note: the snow melt coefficient is not in SI unit, because the temperature is assumed to be in degres Celcius. Unit: [m/degCelcius/s]

Start time of catchment simulation - the earliest time for which the catchment can return data

StormWater LIDs connected to catchment

Time step used during the simulation by the catchment model

Flag telling if initial conditions is taken from a hotstart file Default: false

True if the snow module is activated. If True, a temperature time series has to be provided for the catchment.
