Waterwizard icon drainage overflow threshold.png DRAINAGE_OVERFLOW_THRESHOLD m + datum -10000 to 10000 The threshold of the water end-point of the drainage. n/a

When the drainage is configured to be active drainage, water is pumped from the underground to the waterway until the water level in the waterway has reached the configured threshold.

This attribute can be defined as values over time, using an array of values defining interpolation-time. This allows users to more dynamically define the target water level this drainage system maintains.

Notes

  • When the drainage is not configured as active drainage (and thus behaves as passive drainage), the drainage threshold is ignored.
  • A drainage threshold is only taken into consideration if the Attribute is explicitly defined.
  • If no DRAINAGE_DATUM attribute is defined, a threshold must be defined, otherwise the assumed low positioning of the drainage will prohibit surface water from flowing in or out.
