Mapping Analysis Window is one of the Source processing tools that are installed by default, accessible via  Tools » Analysis Windows » Map» Analysis Windows » Map.... . It displays a map of flows Using this tool, the user will be able to record flows and constituents in bulk for a specified set of sub-catchments (known as reporting region) and/or for a specified set of functional units. This tool helps in displaying a map of flows or constituent loads per sub-catchment . The relevant catchment variables must have been recorded in the scenario run to be able to view them in the Map Analysis Window. You can perform the following functions in this window:

  • To display flows or loads in each sub-catchment, under Map Details, click to open the Run drop-down menu. Choose the run, then the desired Statistic. You can either Use Flow or uncheck the checkbox and select a Constituent from the drop-down menu. Move the mouse cursor over a sub-catchment in the map view. A tool-tip appears near the mouse cursor, indicating the variable amount for that sub-catchment per year (Figure 1);
  • Flows are reported in ML/d and constituent loads in kg/d;
  • You can calculate the difference between two scenario runs by enabling the Subtract checkbox. Carry out the same steps outlined above for the mapping analysis window; and
    • Display results per unit area by enabling the Divide by Area checkbox. 

    of the reporting region. Also, acquisition of basic statistics (such as sum, mean, median, etc.) for a defined period will be possible.


    Two steps need to be done before displaying the results of flows or constituent loads in a map and obtaining the estimated statistics. Firstly, via Edit » Reporting Regions one (or more) reporting region needs to be created. Each of these reporting regions can be included of one or more sub-catchments.

    In the “Mange Reporting Regions” window, right click on the scenario name and click on “Add Reporting Region”. This way one or more reporting regions can be added to the list below the scenario name.
