To create a new initial condition set:

  1. From Initial Condition Set Editor (Figure 9.3), from the Initial Condition Set menu (Figure 9.3), click New. The Create New Initial Condition Set dialog box (Figure 9.4) opens.


  1. Enter a name for the initial condition set (e.g., Initial_CondSet1 in Figure 9.6) in the Name box. Enter a description (optional, but recommended) in the Description box (Figure 9.6). Below the Description are two dropdown lists: WQ Constituent Set and Geometry (Figure 9.6).


  1. From the WQ Constituent Set list (Figure 9.6), select the desired WQ constituent set, and from the Geometry list (Figure 9.6), select the desired geometry dataset.



Figure 9.6 – Create New Initial Condition Set Dialog Box

  1. Click OK to close the Create New Initial Condition Set dialog (Figure 9.6) and save the new initial condition set. The created dataset is added to the initial condition set navigation bar in the Initial Condition Set Editor (Figure 9.6).


  1. The Create New Initial Condition Set dialog (Figure 9.6) also checks if the Initial Conditions Set has a unique name. If the name already exists when the OK button is clicked, then a Duplicate Name message dialog opens (similar to Figure 4.16) stating that the user must enter a unique name for the Initial Conditions Set.


From the Duplicate Name message dialog, click OK; from to the Create New Initial Condition Set dialog (Figure 9.6), enter a unique name in the Name (Figure 9.6) box and click OK. The Create New Initial Condition Set dialog (Figure 9.6) closes, and the created dataset is added to the initial condition set navigation bar in the Initial Condition Set Editor (Figure 9.2).

  1. If either the WQ Constituent Set or Geometry lists are left empty, a warning message opens (similar to No Geometry Selected dialog, Figure 6.10). Close the warning message dialog and select the missing dataset. Click OK to close the Create New Initial Condition Set dialog (Figure 9.6) and save the new initial condition set.


  1. The Initial Condition Set Editor updates with the information contained in the linked Geometry dataset (including the Reservoirs, Junctions, Boundary Condition locations and Observed Data locations, and Reservoir Outflow Junctions). Also, the linked WQ Constituent Set populates the editable tables contained in the Reservoirs, Junctions, and Reservoir Outflow Junctions tabs.
