Represents a linear surface drain. May include natural features as well as constructed where they function as part of a contributed asset.
The type of drain or channel.
Cross-sectional shape of the drain.
The material that the channel is lined with.
The width, in metres, of the lined portion of the channel.
The material that the drain batter is lined with. A null value may be supplied where the drain has no batter.
The total width, in metres, from lip of batter to opposite lip of batter. A null value may be supplied where the drain has no batter.
Calls in the standard elements for upstream and downstream invert levels.
Invert level in metres AHD of this surface drain.
Invert level in metres AHD of this surface drain.
The average gradient over the whole length of the feature, as a percentage. Derivable from the difference in invert levels and the horizontal length of the geometry.
The material length, in metres, of the centreline of the channel.
