Once a wetland link has been specified, double click it to configure it using the wetland link feature editor (Figure 82).

Conveyance link is a type of wetland link used in Source. The discharge across the link depends on the hydraulic conveyance (relationship between reduced level and discharge) of the link and hydraulic head difference between the two ends of the link. 

Weighting refers to the head height at each end of the link. It is the weighting applied to the head height and adjustments to this value are important if there were a significant height difference between the wetland head height and the river head height. A weighting of 0.5 represents an overage of the two head heights. 

If RL1 is the Connector side (river head height m AHD) and RL2 is the wetland side (head height m AHD) of the link, weighting of 0.5 is the average of the head height of RL1 and RL2.

If 0 were used instead, the head height of the Connector would be used to work out the reduced level to determine the direction of the flow of water and if 1 were used, the wetland head height would be weighted.

The weighting uses the same principle as Muskingum x (detailed in storage routing), where x is the weighting factor denoting the importance of inflow relative to outflow.

Ordering at wetlands

In the order phase, wetland clusters can generate orders directly or indirectly, and also be used to supply orders:

...

• Order source: Wetland clusters may be an order delivery source if they are connected to downstream ordering nodes (such as the supply point node) via standard links. However, the ordering system will bypass/ignore wetland links.
