Losses in a river system can be represented in several ways. Some losses, such as reach evaporation,

...

loss to groundwater and filling of dead storage can be simulated through a link. The loss node can be used to represent losses which are not captured by such explicit models. In Source, the loss node allows you to define a relationship between river flow and loss rate.

A piecewise linear function can be entered

 It is advised that you enter a flow rate relationship greater than the likely maximum simulated flow. If you do not, the linear relationship derived from the last two rows of the loss table will be used to calculate any projections. Refer to About piecewise linear editors for more information.

Ownership can also be configured at the loss node. You can specify what proportion each owner in the system will lose. Refer to Loss.
