In a project with multiple Water Overlays, any hydraulic structure can have an OBJECT_FLOW_OUTPUT attribute written to it. However, In a project with multiple such Overlays, it is neccesary to relate which of multiple such attributes relate to which specific Overlay.

How to find the OBJECT_FLOW_OUTPUT related to a specific Overlay:
  1. Open the Query tool.
  2. Set the statement to "SELECT", "ID".
  3. Add a clause.
  4. Set the clause to "OVERLAY".
  5. As option for the clause, select the desired Overlay.
  6. In the constructed query, take note of the displayed number. That is the ID of the Overlay.
  7. Select the Construction of which you want to determine the output for that specific Overlay.
  8. View its Attributes, and find the attributes named "OBJECT_FLOW_OUTPUT", appended with a number.
  9. Find the attribute named "OBJECT_FLOW_OUTPUT", appended with the Overlay ID you found earlier.
  10. That is the attribute with, per timeframe, the amount of flow through that Construction for the desired Overlay.
