All hydraulic structures have an OBJECT_DATUM_OUTPUT_A attribute.

A weir showing the datum heights at that timeframe, obtained from the values of the OBJECT_DATUM_OUTPUT_A and OBJECT_DATUM_OUTPUT_B key stored in that weir.

Notes

  • This attribute does not need to be created when configuring the project. This attribute is created automatically by the Water Overlay when a calculation is performed. When the calculation is complete, the attribute is updated automatically.
  • Each Water Overlay will create this attribute with the ID of an Overlay appended to it, to prevent the results of multiple Water Overlays storing their results in the same attribute by default.
  • This attribute is also visible when zoomed in on a hydraulic structure. The water levels on either side of the structure can be seen at each timeframe when a Water Overlay is selected.
