Object flow output (Water Overlay)

This attribute is automatically created for all relevant hydraulic structures in a project when a water calculation is performed. When the calculation completes the value is updated automatically.

For point-based constructions, a positive value means a net amount of water was added to the surface. A negative value means a net amount of water was removed from the surface. For line-based constructions, positive or negative indicates the net direction the water has flowed.

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.
• Each Water Overlay will create this attribute with a specific number appended to it, to prevent the results of multiple Water Overlays storing their results in the same attribute by default.
• The value is stored per timeframe and represents the amount of water transported in m³ for the period of that timeframe. Therefore the total object flow during the entire simulation can be computed as the sum of the individual values per timeframe.
