The Diversion Editor'sLosses tab ("Figure: Diversion Editor - Losses Tab") allows you to define losses from the diversion channel. Like the Routing tab, the Losses tab is only active for diversions that are connected to a downstream junction. Three options for specifying the channel losses are provided: Return Ratio, Constant Seepage, or Seepage as a function of Flow. Whichever loss method you used, the loss is applied to the routed flow from the diversion channel, right before it enters the downstream junction.
Return Ratio: to describe a consumptive use diversion where only a fraction of the diverted water actually returns to the network, specify a Return Ration between 0.0 and 1.0 (the default is 1.0) to indicate how much of the diverted flow reaches through the diversion to the downstream junction.
Constant Seepage: Enter a seepage value (in cfs or cms) to indicate how much diversion flow will "seep into" the ground and therefore be lost from the system.
Seepage as a function of Flow: Enter a Flow vs. Seepage relationship (in cfs or cms) In the Flow vs. Seepage table to indicate how much of the diversion flow is lost before reaching the downstream junction. The thumbnail plot to the right of the table will reflect the values you enter and can be viewed in full size when you double-click on it.
