Grid Reports

The following grid reports are available for on-premise simulations and for cloud simulations, whose full or summary results have been downloaded to your local results folder:

See below for further details.

Return Period Analysis Report

RPA reports use cumulative flooding onto 2D zone rather than cumulative flow from 2D zone when calculating flood volume at 2D nodes (i.e. nodes whose flood type is 2D, gully 2D or inlet 2D). This means that flows from the surface into the node are not subtracted from the flows from the node onto the surface when the flood volume for the analysis is calculated.

In order to produce a Return Period Analysis report a series of simulations using rainfall of different known return periods must be carried out.

Ideally you would carry out a series of simulations using design rainfall events where the rainfall event was the only variation. Choose a series of return periods for each of a series of storm durations. For example, return periods of 1, 2, 5, 10, 20 and 50 years with durations of 15, 30, 60 and 120 minutes would be a total of 24 simulations. A maximum return period of 200 years can be used with the UK Rainfall Generator.

All the simulations must use the same network.

Using observed rainfall

In most cases you will use design rainfall events. You can however use observed rainfall as long as return period and duration information is available from the rainfall event.

InfoWorks ICM will look for return period and duration values in the rainfall event in the following order:

When using the profile title, the return period and duration of the storm should be formatted as:

5 yr 60 min

where 5 yr is the return period in years and 60 min is the storm duration in minutes. To designate a return period of less than one year a negative number can be used. For example -2 yr would mean a six month return period.

Producing an RPA report

To produce and display an RPA report:

  1. Select Grid report Return period analysis report from the Results menu. The Return Period Analysis Grid Report dialog is displayed.
  2. From the Explorer Window, drag the simulations in which you are interested into the Sim box of the report dialog. For cloud simulations, ensure that the results (full or summary) have been downloaded to your local results folder.
  3. Choose the maximum return period in which you are interested. InfoWorks ICM will display an x in the RPA field of the grid if surcharge or flooding has occurred due to a storm with return period greater than this maximum, or if the return period at which flooding occurred can not be determined from the selected simulations.
  4. Click Produce Grid.

The RPA Report View is displayed.

Exporting an RPA report

Data from the RPA report can be exported to CSV file or, if you have an Autodesk licence, the data can also be exported and automatically uploaded to Info360 Asset.

To export RPA data:

  1. Ensure that RPA data you want to export is displayed in the Return Period Analysis (RPA) report view.

    See the Producing an RPA report section above for further information.

    Note: The Export CSV and Export Info360 buttons are only enabled when you have produced the RPA report.
  2. Click:
    • Export CSV
      A Windows Save as dialog is displayed. In this dialog:
      • Navigate to the folder where you want the CSV file to be saved to.
      • Specify the CSV filename. By default, the network name for the first simulation in the Sim box is displayed in the File name field, which you can edit if required.
      • Click Save.

      The RPA data will be exported to the specified CSV file.

    • Export Info360.

      The results data is exported and uploaded to Info360 Asset.

      Please refer to the Info360 Asset help for information about how to use this data.

Flood Volume Report

A grid report is created that displays flood volumes for each node for one or more simulations. For 2D nodes, the cumulative flooding onto a 2D zone, rather than the flood volume, will be displayed.

There will be a separate Flood/Lost Volume column for each simulation included in the report.

To produce and display a Flood Volume Report:

  1. Select Grid report Flood volume report from the Results menu. The Flood Volume Report dialog is displayed.
  2. From the Explorer Window, drag the simulations in which you are interested into the Sim box of the report dialog.

    For cloud simulations, ensure that the results (full or summary) have been downloaded to your local results folder.

  3. Click Produce Grid.

The Flood Volume Report View is displayed.

Worst Case Report

The Worst Case Report allows you to compare a number of simulations and display the worst case for one of a number of node or conduit parameters.

The Worst Case options for InfoWorks simulations are:

The Worst Case options for SWMM simulations are:

When displaying the worst case for a node or conduit, ICM also displays the summary results for that node or conduit from the simulation that produced the worst case.

In order to produce a Worst Case Report you will first need to carry out a series of simulations using different rainfall events.

The report will display return period and duration values, if the information is available from the rainfall event. When using observed rainfall, ICM will look for return period and duration values in the rainfall event in the following order:

When using the profile title, the return period and duration of the storm should be formatted as:

5 yr 60 min

where 5 yr is the return period in years and 60 min is the storm duration in minutes. To designate a return period of less than one year a negative number can be used. For example -2 yr would mean a six month return period.

All the InfoWorks simulations must use the same InfoWorks network, and all the SWMM simulations must use the same SWMM network.

To produce and display a Worst Case Report:

  1. Select Grid report Worst case report from the Results menu. The Worst Case Grid Report dialog is displayed.
  2. From the Explorer Window, drag either the InfoWorks or SWMM simulations in which you are interested into the Sim/SWMM sim box in the report dialog.

    For cloud simulations, ensure that the results (full or summary) have been downloaded to your local results folder.

  3. Select the object type and parameter to be displayed in the report.
  4. Click Produce Grid.

The Worst Case Report View is displayed.

Velocity Profile Report

The Velocity Profile Report provides a detailed breakdown of flow, bulk velocity and wetted area for a selection of river reaches. Values are provided at each timestep for each river reach section as a whole and for individual panels that make up the sections.

Tip: The date-times included in the report can be restricted by setting the start and end times on the Replay Options Dialog. For this to take effect the Apply to Grid and Graph Tools check box must be ticked on the Replay Options Dialog.

Values may be displayed in a grid view or exported to csv files.

To produce and display a Velocity Profile Report:

  1. Select Grid report Velocity profile report from the Results menu. The Velocity Profile Grid Report dialog is displayed.
  2. From the Explorer Window, drag the simulations in which you are interested into the Sim box of the report dialog.

    For cloud simulations, ensure that the results (full or summary) have been downloaded to your local results folder.

  3. Optionally specify a Selection list
  4. Select the Report format to be used
  5. Click the Produce Grid button to display the Velocity Profile Report View or the Export to CSV button to export the results to csv format.

Printing a report

There are a number of options available that allow customisation of the printed output from Grid Reports. Margin, title and user defined logo options can be set in the Grid Page Setup dialog. Access the dialog by selecting Page setup from the File menu when the Grid Report is the currently active window.

A Print Preview option is available when printing the Grid Report. Access the preview by selecting Print preview from the File menu.
