Model output

Revision as of 10:52, 1 October 2012

The model results are displayed in two different ways:

• Graphical display
• Numerical display

Graphical display

The 'TSVisualization' component of the JAMS builder brings graphical display of different output variables. The 'TSVisualization' componen can be expanded (click + and - sign on the left side to expand and reduce) as shown in Figure below. The existing TS plots will be shown. The new plot can be created by using the existing plot. Drag one of the existing plots (example, Glacier contribution) and hold CTRL key (a + sign will appear) and leave both the keys. The new plot will appear with the new name (Glacier contribution_1). From the right window, the name and the values of the new plot can be changed. Mainly, four things has to be changed for the new plot.

1. Change the name of the component. Click the [...] box on the right hand side of the 'Name'. This will bring a new window and you can change the name of the new plot.

2. Provide new names for the legend used in the plot. Click on the 'titleLeft' row and change the name of the legends under 'Value' window. In case of more than one legend, seperate the name by semicolon.

3. Provide colors to the legends. Click 'colorLeft' row and change the color name under 'Value' window.

4. Provide value for the legends. When 'valueLeft' row is clicked, the window below is activated. The value can be choosen from Timeloop. Use CTRL key to choose more than one value.

Alternatively, this information can be changed by editing the model xml file which has been explained below.

With these lines in xml file as shown in figure below, users can define which output files they wish to see as a plot/graph. In the figure below, four different runoff components are displayed.

After defining the plot, users also need to define a line in a 'Plot & Maps' component of the xml to bring it in the JAMS framework. This has to be done by directly editing the model xml. For example: The first line is dedicated to display the Runoff plot.

The Runoff Plot will appear in Plots & Maps group in the JAMS launcher after loading the xml file in JAMS, which users can tick on/off to display as a graph. Similarly, the spatial distribution of some variables can also be seen, for which the different component of maps has to be activated, as shown in Figure below. In this example, the average evapotranspiration of the model run period are displayed.

After running the model, users can see the plot of different variables as provided below:

• Runoff components

• Spatial distribution of evapotranspiration

The values are provided in daily average. Users can zoom in and out the map. Similaly, the values can be downloaded by clicking the save botton (the red box in right hand side). The GIS shape file with HRU ID and values associated with each HRUs are saved.

• Spatial distribution of evapotranspiration (3D)

Numerical display

The model outputs on a daily resolution are provided in the output folder (current-->> Timeloop.dat filename) after each model run. The variables which need to be produced as output data is deterimed inside the TimeLoop.xml file which is placed outside the current folder.

The TimeLoop.xml has daily output variables as shown in Figure below. If users do not need some variables, they can comment out the particular variables as shown in the case of netRain in the figure.

• HRULoop.xml file

The HRULoop.xml is responsible for producing the daily average values of each variables of interest (as defined inside the xml file) for all HRUs. Users can comment out some variables as shown in the case of wind below.

• TimeLoop.xml file

Folder: parameter

The folder contains parameter files (hgeo.par, hru.par, landuse.par, reach.par, soils.par). Please remember that these names should be same in the model xml file.

Folders: explorer and tmp

The other folder inside the workspace is explorer and tmp which is used to dump some temporary files generated while running the model.
