In ResSim, a Diverted Outlet is used to represent a withdrawal (or release) of water from the reservoir pool. In the Reservoir Tree, a diverted outlet is a special type of outlet group. Three things make a diverted outlet special with respect to a normal outlet group:

  • A Diverted Outlet is attached directly to the Reservoir in the Reservoir Tree, parallel to the Dam and Pool.
  • A Diverted Outlet is always created with a Controlled Outlet in it. If you want to replace the default outlet with some other type of outlet, add the new outlet first before deleting the default outlet.
  • If the diversion (arrow) of the Diverted Outlet is connected at its downstream end to a Junction in the network schematic, a Routing node will be included in the Diverted Outlet group. See "Reach Editor: Routing Tab" for information about the available routing methods.

Adding a Diverted Outlet to a Reservoir

A Diverted Outlet cannot be added to a Reservoir from the Reservoir Editor in ResSim. Instead, a Diverted Outlet can be only added to the reservoir by using the Diverted Outlet tool to draw a reservoir diversion from the reservoir in the network schematic in the Map Display area.

Once a diverted outlet has been added to the reservoir in the schematic, a new Diverted Outlet  branch from the Reservoir will be added to the Reservoir Tree in the Reservoir Editor ("Figure: Reservoir Tree with Diverted Outlet"). By default, a Controlled Outlet is included in the Diverted Outlet group when the diverted outlet is added to the reservoir. If you want to replace the default outlet with a different outlet, create the new outlet before deleting the default one. To add an outlet to the diverted outlet group, select the Diverted Outlet in the Reservoir Tree then use the diverted outlet's context menu (or the Outlet menu) to add an outlet to the diverted outlet.

When you select the Diverted Outlet node in the Reservoir Tree, the Edit Panel displays the Diverted Outlet pane ("Figure: Diverted Outlet Pane - Composite Release Capacity Table"). Like the Group pane, the Diverted Outlet pane contains the name of the Diverted Outlet and a non-editable Composite Release Capacity table which reflects the total capacity of the outlets contained in the Diverted Outlet group.
