The links connecting source, treatment, and junction nodes may represent pipes, open channels, or natural watercourses. To enable more accurate simulation, the routing properties of each link may be specified by the user.
Location
Drainage link identifier.
Routing Properties
You may specify no routing, translation only, or full Muskingum-Cunge routing for any link in a treatment train. If you specify no routing, no further input is required.
If you specify translation only, select an appropriate translation time K using the spinner arrows. Translation time will always be a multiple of the time-step for this catchment.
If you select Muskingum-Cunge routing, enter appropriate values for the parameters K and Theta. K is equivalent to a translation time, while Theta measures the relative effect of inflow and outflow on the behaviour in a reach. For more information see Routing Stormwater Using the Muskingum Cunge Method Cunge Method.
Outflow Components
The Outflow Components describes the outflow components that are represented by this drainage link. If using a 'Primary' drainage link, these outflow components cannot be altered. However, if using a 'Secondary' drainage link, the outflow components can be updated by checking or unchecking the appropriate tick box.
