Using statistical reports

Step-by-step guide

Statistical reports can be generated from the results of one or more simulations. The reports contain summaries relating to selected locations and attributes. Statistical summaries are produced by first defining the relevant criteria in a Statistics Template. This template is then applied to the results of one or more simulations to generate statistical results.

This example uses a statistics template to analyze the impact of previously created sluices with RTC conditions. To complete this exercise, open the transportable database .icmt file for this tutorial.

Start by running the simulations with the Tank Storage scenario:

1. In the Database, right-click TSR Run and select Open.

2. Update the Run title to "TSR Tank Test".
3. Click Update to latest to make sure all the latest changes are included.
4. In the Scenarios list, select Tank Storage.
5. Click Run Simulations.
6. In the Schedule Job(s) popup, click OK.

While the simulation is running, set up the statistics template:

7. In the Database, right-click the Use_Stat_Rprts folder and select New InfoWorks > Statistics template.
8. Enter the name "Storm Tank Analysis".
9. Click OK.

In the Statistics Template dialog box, define the analysis rules. By default, it is set to analyze links and DS flow.

10. From the Model Group, drag the Storm Tank Spill selection list into the Statistics Template dialog box and drop it into the empty area under Location.

This auto-populates the location information with the stored spill link.

11. Set the Threshold1 field to 0.0001, to prevent minor instabilities from affecting the results.

12. Click Save.
13. Close the dialog box.

By this point, the simulation should be complete, so a statistics report for the results can now be run:

14. From the Results menu, select Statistical reports.
15. From the Database, drag TSR Run into the Compose Statistical Report dialog box, and drop it into the Sim section.
16. Drag TSR Run Tank Test into the Sim section.
17. Drag Storm Tank Analysis into the Statistics template section.
18. Click Produce report.

19. In the popup, click Yes to prepare the statistics.

The Statistical Report View is generated and contains information for the spill link.

20. Click the Exceedance summary tab.

The Exceedance summary grid contains the most concise information and shows that the Total Volume (m³) has been reduced from the original TSR Run to the Tank Test run.

These statistics can be copied and pasted into a spreadsheet, or they can be exported to CSV files by selecting Statistics > Export statistical data.

21. Close the Statistical Report View.

To compare the two simulations directly:

22. In the Database, right-click the base model simulation 2001 Typical Year_Evap and select Open to open the model in the GeoPlan.
23. Right-click the Tank Storage 2001 Typical Year_Evap simulation and select Open as.
24. In the Select results popup, select As alternative results for comparison.
25. Click OK.

In the GeoPlan title bar, notice that both simulation names now appear.

26. On the GeoPlan, double-click a node which should be impacted by the RTC.
27. In the Properties window, compare the two columns of results.

To compare the results using a graph:

28. In the Results toolbar, click the Graph tool.
29. From the model, select a link.
30. In the Graph popup, choose the attributes to graph, such as Flow.
31. Click OK to open the graph.
