AQUIS conversion notes

Network and Control Data information can be imported from an AQUIS Hydraulic Static Data Input (.DAT) file.

If an AQUIS .cf1 file is also present, time series data will also be imported.

This topic discusses how InfoWorks converts existing AQUIS network components into an InfoWorks network and InfoWorks control objects. Some data is not imported at all, or is only partially imported. Some AQUIS objects are imported as more complex InfoWorks objects, and additional data will be required to completely define these InfoWorks objects.

The following keywords are read from the .dat file by the IWWS AQUIS importer:

The following keywords are read from the .cf1 file by the IWWS AQUIS importer:

Values are assumed to be metric values.

*HAZW - Hazen Williams Friction Formula

The AQUIS *HAZW keyword is used to is used to switch from the Colebrook-White friction formula to the Hazen-Williams formula.

If the *HAZW keyword is not present in the AQUIS .DAT file, all pipe friction data is imported as CW.

If the *HAZW keyword is present, pipe friction data is imported as HW. The exception to this is for IWWS  Pump Stations created from AQUIS node pump controls and IWWS Float Valves created from AQUIS air controlled valves. In these cases, the friction type is set to DW with a small nominal friction factor.

*NODE - Nodes
