In the example used in this manual, the ResSim model alternative will obtain most of the flows needed from the HMS model alternative, as well as some observed data (such as flows, storage elevations, etc.). Initially, the model linking for the ResSim model alternative defaults to the extract list (Figure 7.7).

        1. From the table, highlight all of the locations, with the parameter Known Flow, click Select Input Model Alternative (Figure 7.7), the Select Input Model Alternative dialog box will open (Figure 7.8).


        1. From the Input Model Alternative list (Figure 7.8), select the correct HMS model alternative. Click OK, the Select Input Model Alternative dialog box will close (Figure[ 7.8|#_bookmark97]), and a Confirm Input Selection message window will appear (Figure 7.9). The message window is asking the user if this linking is appropriate for the selected rows. Click Yes, the Confirm Input Selection message window will close (Figure 7.9).

        1. Now on the Model Linking Editor (Figure 7.10), all of the selected rows will now have a linkage to an HMS model alternative in the Input From (Figure 7.10) column.


        1. Instead of following the instructions in Step 2, the user can select a location, click Browse (Figure 7.10), the Select Source Data Location dialog box will open (Figure[ 7.11|#_bookmark100]). Using the Select Source Data Location dialog box, for some users another way of performing the linking that might be easier than doing the linking from the table (Figure 7.10). Once the user has highlighted the correct location, click Set Location (Figure 7.11). The table in the Model Linking Editor (Figure 7.10) is updated with the selection made. The user can keep on making selections and changing the linking, until finished.

        1. The user should review the ResSim model linking to check that the correct location and parameter has been selected. HEC-RTS will do the best it can to match datasets, but if location names are not the same, then HEC-RTS tries to match items, and sometimes the software does not select correctly. HEC-RTS does try to help the user, by highlighting items in purple when the software thinks there is a duplicate linking (Figure 7.10).


        1. Once the user has verified the linking for the ResSim model alternative, click Apply

(Figure 7.10) to save the model linking for the ResSim model alternative.
