Diversions remove water from your river system at junctions in your reservoir network.
If a diversion is connected at its downstream end to another junction in the network, that diversion is said to be "connected" and the downstream junction will receive the routed diversion flow as inflow. Connected diversions have a reach component to allow you to specify the routing and channel losses through the diversion reach. If a diversion is not connected at its downstream end, it is said to be "unconnected", and it removes the diversion quantity of flow from the network completely.
Diversions take priority over a reach or reservoir that may be connected to the outflow of the junction, so if there is not enough flow entering the diversion's source junction to meet the specified diversion quantity, the diversion will get all there is, and the downstream element will receive zero inflow. Although unusual, a diversion is allowed to have a negative diversion quantity; a negative diversion will be seen as inflow to the junction.
Use the Diversion Editor ("Figure: Diversion Editor") to specify the diversion flow (or demand) for each diversion in your network.
The Diversion Editor has four tabs for defining the data related to your diversion:
- Diversion
- Losses
- Routing
- Observed Data
These tabs are described in the following sections.
NOTE: the Losses and Routing tabs are available only for connected diversions (diversions that connect to another junction at their outflow).
