Importing InfoDrainage Data

Data from InfoDrainage models can be imported to InfoWorks ICM using files in the IDDX format.

Note

Only network data from storm phases will be imported; import of foul phase data is not currently supported.
Notional connection types (no delay & lagged flow) are also not supported and will therefore not be imported.

Tip

Hydrograph Inflows from InfoDrainage IDDX files can be imported as an Inflow event. See Importing Event Data for further information.

To import InfoDrainage network data:

  1. Open the network to be updated.
  2. Select Import | Model | from InfoDrainage data from the Network menu, and a standard Windows Open dialog is displayed.

    ClosedShow me

  3. Select the .iddx file to be imported.
  4. Click Open.

An import report will be displayed with any import errors or warnings. It will also include the full path of the iddx file which was imported together with the full path in the InfoWorks ICM tree of the target network.

ClosedShow me

Create New Node dialog

For an iddx file with a single InfoDrainage network, all data is imported into the currently selected scenario of the target network in InfoWorks ICM.

For an iddx file with multiple InfoDrainage networks, the data from each InfoDrainage network is imported into a different scenario in the target network. For example, a InfoDrainage network with name "XXXXX" the corresponding scenario in InfoWorks ICM is named "ID_XXXXX". If a scenario does not already exist, a new one will be created.

For each scenario the report provides the total number of imported objects of different types.

Note

Due to the display precision set on the property fields in InfoWorks ICM, some of the displayed values of the imported InfoDrainage attributes will be truncated. However, the attribute value imported to the master database from InfoDrainage will not be truncated.

For details of the objects imported and any conversions made by the InfoDrainage Importer, see the Import Notes below.

  Storage array storage_array

The 'shape' of the pond (Circular or Square) is determined from the setting in the InfoDrainage Pond's Perimeter attribute.

At least two records will be added to the storage array for each type of pond shape as follows:

InfoDrainage Attribute ICM Field Notes
First record
Depth Level  
Area Area

 
  Perimeter

For a pond with a Square type of perimeter, this is calculated as:

2 x Length + 2 x (Area / Length), if Length >0; otherwise 4 x √Area

For a pond with a Circular type of perimeter, this is calculated as:

2 x Pi x radius, where radius = √Area/Pi
Subsequent record
Depth Level  
Area Area  
  Perimeter

For a pond with a Square type of perimeter, this is calculated as:

2 x Length + 2 x (Area / Length), if Length >0; otherwise 4 x √Area

For a pond with a Circular type of perimeter, this is calculated as:

2 x Pi x radius, where radius = √Area/Pi

If the final record's level is not equal to the ground level, another record with a level equal to the ground level and with an Area and Perimeter the same as the previous record, will be generated.
