Last updated 1 year ago

The next tab in the GUI is the Modules tab. In this tab you need to select the SPHY model modules for which you want to create input data. The input maps that are created are shown in the Maps to process log window. If no modules are selected, then the 12 maps as shown in Figure 64 will be created by default. After selecting one or more modules more maps that need to be processed are shown in log window (Figure 65).

f you are finished selecting the required modules, then click the Create initial maps button to start processing these maps. This may take some time depending on the extent, spatial resolution, and number of modules that have been selected. During processing of the input maps, the Process log window of the Modules tab looks like Figure 66. After each map has been processed it will be added to the QGIS canvas automatically. After processing has been completed the message Processing is finished" will appear. You can change the colors/layout of each layer if you wish by clicking the right mouse button on the layer and then pressing Properties.

If you are satisfied with the processed maps you can continue to the next tab. This next tab is Basin delineation (Section 5.5) if you have selected the Routing module. If this module has not been selected, then the Basin delineation tab is inactive and you can continue to the Stations tab (Section 5.6). If you do not need the SPHY model to report time-series output, then you also can skip the Stations tab and move on to the Meteorological forcing tab (Section 5.7).
