5.13 Visualizing model output

If model execution has been completed successfully, then the Visualize results tab will become available. An overview of the Visualize results tab is shown in Figure 51. If no model run has been performed yet, or if nothing was reported in the Report options tab, then the list widgets in this tab will be completely empty.

A distinction has been made between time-series output (left list widget) and map-series output (three right list widgets). Map-series output has been split into three separate list widgets, being i) daily maps, ii) monthly maps, and iii) annual maps.

5.13.1 Time-series output

Time-series plots can be shown for the locations that are defined in the Stations map in the General settings tab (Section 4.4.4). In order to show a time-series plot you need to:

1. Select the variable of interest from the list (in Figure 51 the "Routed baseflow runoff [m3/s]" is the selected variable).

2. Make sure that the Stations map layer (outlet) is selected in the map canvas (Figure 52).

3. Click the Show time-series button.

4. Finally, click on one of the points in the canvas that is part of your Stations map layer (Figure 53).

After completing step 4, a time-series plot will be shown (Figure 54). The buttons shown inside the red box allow you to zoom in and zoom out of your graph, pan through the graph, change azis and label settings, and save your graph to an image file.

5.13.2 Map-series output

Showing map-series output is more straightforward than the plotting of time-series. An output map (daily, monthly, or annual) can be added to the canvas by selecting the map of interest from the list widget, and subsequently press the Show XXX map button at the bottom of the list widget, with XXX being daily, monthly, or annual.

Within the QGIS map canvas three-layer groups are defined within the Output group layer, being:

• Daily

• Monthly

• Annual

The selected map output will be inserted as a new layer in one of these groups. If the layer name already existed in the group, then this layer will be overwritten with the new selected map layer. Figure 55 shows an example of adding an annual rainfall map to the map canvas. Since it is an annual map, it will be inserted inside the Output – Annual layer group.
