From the HEC-ResSim main window, from the Water Quality module (Figure 7.2), from the Water Quality menu (Figure 7.3), click Observed Data. The Observed Dataset Editor (Figure 7.1) opens.
From the Observed Dataset Editor (Figure 7.4), from the Observed Dataset menu (Figure 7.4), click the New menu command. The Create New Observed Dataset dialog (Figure 7.11) opens.
From the Create New Observed Dataset dialog, enter a name in the Name field (e.g., New_ObsData2 in Figure 7.10), and a description (optional, but recommended) in the Description field (Figure 7.11).
Figure 7.11 – Create New Observed Dataset Dialog Box
Below the Description are two selector panels that list all available (Inactive Obs Stations panel) and selected (Active Obs Stations panel) observed stations (Figure 7.11). The observed stations are listed in alpha-numeric order in the selector panels.
By default, the Active Obs Stations panel contains all observed stations in the watershed (e.g., DryCk_10 and Lake Mendocino Outflow in Figure 7.11). Use the selector panels to select the observed stations that are active or inactive for the new or edited Observed Dataset.
From the Active Obs Stations (Figure 7.11), select the locations to remove from the active list and add to the inactive list, and click Remove (Figure 7.11) to set the locations as Inactive Obs Stations for the created observed dataset.
Click OK to close the Create New Observed Dataset dialog (Figure 7.11) and save the new observed dataset. The created dataset is added to the observed dataset navigation bar in the Observed Dataset Editor (Figure 7.10).
If the user sets all stations as inactive (e.g., clicks the Remove All button) and clicks OK, then a Warning message dialog opens (similar to Figure 3.6). Each observed dataset must have at least one active observed station. From the Warning message dialog, click OK, and from to the Create New Observed Dataset dialog (Figure 7.11) add at least one station to the Active Obs Stations (Figure 7.11) list, and click OK.
The Create New Observed Dataset dialog (Figure 7.11) also checks if the Observed Dataset has a unique name. If the name already exists when the OK button is clicked, a Warning message dialog opens (similar to Figure 3.19) stating that the user must enter a unique name for the Observed Dataset. From the Warning message dialog, click OK, then from to the Create New Observed Dataset dialog (Figure 7.11), enter a unique name in the Name box and click OK.
The Create New Observed Dataset dialog (Figure 7.11) closes, and the created dataset is added to the observed dataset navigation bar in the Observed Dataset Editor (Figure 7.12). The created observed dataset also opens in the map window schematic in the HEC-ResSim main window. In other words, from the module data, from the Observed Dataset dropdown (Figure 7.12), the created dataset is automatically selected (e.g., Observed_Data2 selected in Figure 7.12). Click OK to close the Observed Dataset Editor (Figure 7.10), or begin to define the observed input data (see Section 7.4).
