flowConstriction
A split in the network captured to indicate a hydrographic point of interest or facility, or a man-made object that affects the network flow. This attribute is not manifested in this release of the data; however, it will be utilised in future data updates.
flowRegulation
A split in the network captured to indicate a man-made object that is used to regulate the network flow. This value is not currently supplied.
junction
A split in the network to indicate where three or more WatercourseLink features meet at the same level, for example, confluences or bifurcations.
Outlet
The end terminal of a set of one or more interconnected links that does not have any downstream flow, for example, where a watercourse sinks into the ground or the point where a river enters the sea.
Source
The start terminal of a set of one or more interconnected links that has downstream flow, for example, springs or collects.
Pseudo
A location where the real-world attribution of a watercourse changes that requires a WatercourseLink to be split.
boundary
HydroNode used to connect different networks.
Note: Can be used to connect cross border networks or adjacent networks together. Differs from source / outlet in that in the real world there is an adjacent link that is not present in the dataset supplied.
