The purpose of the Import Network Wizard (or Network Importer) is to copy a network from one watershed into another. This is usually needed when an existing watershed is copied and used for a different purpose or study than that of the original model. During its use in the newer study, the model may have evolved and been enhanced in ways that could be useful in the context, or for the purpose, of the original watershed.

However, since the new (copied) watershed "evolved", there may be differences in the underlying framework (the stream alignment and/or configuration) of the network to be imported that must be addressed in order for that network to function as a native part of the watershed it is being imported into.

In addition, there's nothing to prevent you from importing a network from a watershed that did not share its development path with the watershed it is being imported into. The source watershed could be older or lacking in some way (or even broken) and by importing its network into a newer or more complete watershed, the older network can be updated and used as part of the new watershed.

The steps for importing a Reservoir Network into your current watershed are as follows:

  • From the Reservoir Network module, select Import Network… from the Network menu ("Figure: Network Menu - Import Network...").

  • The Import Network Wizard will open ("Figure: Import Network Wizard - Step 1 - Select the Watershed"). In Step 1 of 6, select the watershed to copy from. The Watershed Locations area shows the list of your Shortcuts to directories on your computer. Highlighting each will show a list of watersheds in the right-hand side. Select the desired watershed to copy from and click Next.

The steps for importing a Reservoir Network into your current watershed are as follows:

  • From the Reservoir Network module, select Import Network… from the Network menu.

  • The Import Network Wizard will open. In Step 1 of 6, select the watershed to copy from. The Watershed Locations area shows the list of your Shortcuts to directories on your computer. Highlighting each will show a list of watersheds in the right-hand side. Select the desired watershed to copy from and click Next.

  • In the Import Network Wizard—Step 2 of 6, a list of available networks in your chosen watershed will be shown ("Figure: Import Network Wizard - Step 2 - Select the Network to Import Elements from"). Select the network you wish to copy into your current watershed and click Next.

  • Set the new network name and description in the Import Network Wizard—Step 3 of 6 ("Figure: Import Network Wizard - Step 3 - Set New Network Name and Description"). All networks in your current watershed are listed under Existing Reservoir Networks. At the bottom, under New Reservoir Network, create a new name and description for the imported network.

  • Click Next to open the Import Network Wizard—Step 4 of 6 ("Figure: Import Network Wizard - Step 4 - Assign Stream Names").The Assign Stream Names dialog shows a table listing each Imported Element, Element Type, and its location (From Stream) in the originating ("import from") watershed. The final column "To Stream" gives the location to which the element will be imported in the current watershed. ResSim will automatically populate the "To Stream" fields, if it can match a stream name in the "import from" watershed to a stream name in the current "import to" watershed. Update the field using the dropdown menu to select from the list of streams in the current watershed.

  • You can also use the Assign Stream Names button to associate streams in the "copy from" watershed with streams in the "copy to" watershed. Clicking this button will open the Select Stream Name editor ("Figure: Import Network Wizard - Select Stream Name"). Once you have associated the streams, click OK, and this will update all the imported element "To Stream" fields accordingly.

  • Click Next to go to the Import Network Wizard—Step 5 of 6 ("Figure: Import Network Wizard - Step 5 - Resolve Network Computation Points"), where you will Resolve the Network Computation Points. The table lists every Imported Element name and type and indicates the associated current Watershed Computation Point. Verify that these are correct, or if they are blank, select them with the dropdown menu. Sometimes an imported element can't be matched to a similar location in the current watershed. When this happens, consider how the two watersheds differ and whether you need to make a change before importing. If the computation point can't be resolved, the associated element will not be imported. Click Next, and if there were issues, you will see a warning with a list of any import elements that were not assigned computation points and will therefore not be imported into your current watershed. You can choose the Back button if necessary.

  • The Import Network Wizard—Step 6 of 6 shows a summary of all the import information ("Figure: Import Network Wizard - Step 6 - Import Summary"). Obvious issues will be in red font. Once you are satisfied with the summary, click Finish to complete the import, or select Back to make changes in previous steps. If you are sure about the import, confirm by selecting Yes in the Continue with Import dialog. Choosing No will return you to the Wizard's Step 6 of 6.
