UND File Conversion - Orifices

Data in the [MOUSE_ORIFICES] group of the UND file is imported into the InfoWorks ICM Orifice or Sluice table. This topic contains details on the conversion of MOUSE orifice/gate information to InfoWorks ICM.

Orifice Group - [MOUSE_ORIFICES]

MOUSE

Description

InfoWorks ICM Data Field

ORIFICEID

Orifice name

Asset ID

FROMNODE

Upstream node

US Node ID

TONODE

Downstream node

DS Node ID

If TONODE is not specified, an outfall node is created downstream of the orifice, named <us node id>_out.

TYPENO

Orifice/Gate Shape

TYPENO

Exported to InfoWorks ICM as follows:

Note on CRS sections:

There is no direct equivalent in InfoWorks ICM to the MOUSE CRS orifice.

MOUSE CRS gates are converted to InfoWorks ICM Sluice objects. (A warning message will be displayed on import.)

The cross-section is imported as an InfoWorks ICM Shape for reference and the cross-section ID added to User Text 1.

CRSID

Cross Section ID defining geometry of Cross Section Shape orifice.

Cross Section geometry is defined in the Cross Sections section.

A user defined Shape is created with Name = MOUSE CRSID.

Data from the CROSS SECTIONS target in the UND file is imported into the Height and Width arrays of the Shape.

MOUSE height and width values are adjusted to fall between 0 and 1.

SCALINGTYPENO

Scaling type, used for CRS shape types:

SCALINGTYPENO

Scaling Type

1

Scale

2

Height and Width

Used to determine the values to be exported to the Sluice Width and Opening fields.

DIAMETER

Diameter of circular pipes

Orifice Diameter

SCALEORWIDTH

Scale factor or width, used for CRS and Rectangular shape types.

Width of pipe for Rectangular shape types.

For CRS shapes:

  • If Scaling Type = Scale, this is the scale factor used for cross-sections (CRS types).
  • If Scaling Type = Height&Width, this is the width of the cross-section.

For MOUSE Rectangular sections:

  • Exported to Sluice Width field.

For MOUSE CRS shapes:

  • If Scaling Type = Scale, Width is calculated as:

    • Scale Factor x Maximum CRS Width

  • If Scaling Type = Height and Width, exported directly to Sluice Width field

HEIGHT

Height

For MOUSE Rectangular sections:

  • Exported to Sluice Opening field.

For MOUSE CRS shapes:

  • If Scaling Type = Scale, Opening is calculated as:

    • Scale Factor x Maximum CRS Height

  • If Scaling Type = Height and Width, exported directly to Sluice Opening field

INVERTLEVEL

Invert Level

Invert Level

CONTROLTYPENO

Type of gate control:

CONTROLTYPENO

RTCControl

Exported to Sluice Link Type as follows:

MOUSE Control Type

 InfoWorks ICM Link Type

NoControl

Sluice

VSGate

MAXSPEEDUP

Maximum speed at which gate can raise

Positive Speed

(Not directly equivalent, as InfoWorks ICM Positive Speed is speed, not maximum speed.)

MAXSPEEDDWN

Maximum speed at which gate can lower

Negative Speed

(Not directly equivalent, as InfoWorks ICM Negative Speed is speed, not maximum speed.)

MAXLEVEL

Maximum level of gate

Maximum Opening

Maximum level is specified as mAD in MOUSE and m in InfoWorks ICM.

InfoWorks ICM Maximum Opening is calculated from MOUSE values as:

MAXLEVEL - INVERTLEVEL

MINLEVEL

Minimum level of gate

Minimum Opening

Minimum level is specified as mAD in MOUSE and m in InfoWorks ICM.

InfoWorks ICM Minimum Opening is calculated from MOUSE values as:

MINLEVEL - INVERTLEVEL

Calculation of Discharge Coefficients for Sluice Gates

In all cases, the InfoWorks ICM primary and secondary discharge coefficients are calculated using the same method as for MOUSE weirs using the Weir Formula method when a discharge coefficient is not supplied. It is assumed that the orifice is inline with the flow i.e. the angle to the direction of flow is 0°.

See Calculation of Coefficient of Discharge for Weirs for details.
