Importing HydroWorks Network Data

To import HydroWorks network data:

  1. Open the network to be updated
  2. Select Import | Model |from DSD/SSC file... from the Network menu. This displays the HydroWorks DSD Import Dialog.
  3. Select the files to import. Either type in the path and filenames or press the button to the right of the field to browse for them. See the list below for more information.
  4. Select the Network Roughness Type to be applied to the network if the DSD file to be imported contains negative values:
  5. Positive roughness values in a DSD file are Colebrook-White values. If the DSD file to be imported contains positive roughness values, network roughness type will automatically be set to Colebrook-White.

    Negative roughness values in a DSD file can be either Manning or reciprocate Manning values. If the DSD file to be imported contains negative values, network roughness type will be set to the selected option.

  6. Decide how the comments in the DSD file are to be handled:
  7. Click on OK to import the files. The import process may take some time depending on the size of the network. During import, the system type for imported objects will be set to Other.
  8. Enter a unique title for the network and click on OK.

Import Files

The table below describes the files you can import when creating your imported network. Many of the files are essential, and set up default parameters for both the network, and simulations using the network.

You do not have to include a DSD file. You can set up a blank network with all the defaults by importing all the other file types without any network object data.

In many ways this is preferable to creating a new network. A brand new network will not include things like the default land use definitions and runoff surfaces from the default.lud and default.rpf file.

File

Description

Essential

Default Available

HydroWorks drainage system (.DSD or .SSD)

Surprisingly, the network is not essential. You may want to create a blank network using non-standard parameters, such as a file of additional shapes.

NO

NO

Shape (.SHP)

InfoWorks ICM contains a number of built-in conduit shapes. Import a shape file if the network uses additional shapes

NO

NO

Land use (.LUD)

Import a specific Land Use file for your network.

YES

YES

Runoff parameter (.RPF or .PRM)

Import a specific Runoff Parameters file for your network.

YES

YES

Washoff Parameters (.WPF)

Closed

Water Quality

This section is relevant only to Water Quality Simulations. If the icon is at the start of a paragraph, then that paragraph is only relevant to water quality simulations. If the icon is at the top of a topic, or a section (underneath a section title), or a row in a table, then the complete topic, section or row is only relevant to water quality simulations.

Import a specific Washoff Parameters file for your network.

Washoff data is only used in water quality simulations. Forcing you to import a Washoff parameters file ensures that all networks are valid for both hydraulic and water quality simulations

YES

YES

Headloss curve (.HLC)

InfoWorks ICM contains four built-in headloss curves. Import a headloss curve file if the network uses additional headloss curves

NO

NO

Simulation parameter (.SIM)

Import a specific Simulation Parameters file for your network.

YES

YES

Water Quality Parameters (.QSM)

Closed

Water Quality

This section is relevant only to Water Quality Simulations. If the icon is at the start of a paragraph, then that paragraph is only relevant to water quality simulations. If the icon is at the top of a topic, or a section (underneath a section title), or a row in a table, then the complete topic, section or row is only relevant to water quality simulations.

Import a specific Water Quality Parameters file for your network.

Water Quality Parameters are only used in water quality simulations. However, InfoWorks ICM forces you to import a Water Quality parameters file every time. This ensures that all networks are valid for both hydraulic and water quality simulations
