Inlet Details for Part Builder Structures
Use these settings to define default values for parts that don't currently have these values applied. These values are applicable to parts created with the Part Builder and are used by the Analyse Gravity Network command for inlet analysis calculations.
- Gully Width
- Specifies the default gully width for gully or combination inlets. This dimension is perpendicular to flow along the channel.
- Gully Length
- Specifies the default gully length for gully or combination inlets. This dimension is in the direction of flow along the channel.
- Gully Open Area
- Specifies the default gully open area for gully or combination inlets. This is the area between the bars of the gully through which water can flow.
- Kerb Opening Height
- Specifies the kerb opening height for kerb or combination inlets.
- Kerb Opening Length
- Specifies the kerb opening length for kerb or combination inlets.
Channel Detail Defaults
The Channel Detail Defaults settings are not physical properties of the inlet structure but rather are properties of the carriageway area around the inlet. They're used by the Analyse Gravity Network command for inlet analysis calculations for grate inlets, kerb inlets, or combination inlets.
- Road Sx
- Specifies the road cross slope.
- Channel Sw
- Specifies the channel cross slope.
- Channel Width
- Specifies the channel width.
- Longitudinal Slope
- Specifies the slope along the road at the inlet. This property is used for on-gradient inlets.
- Channel n Value
- Specifies the roughness of the channel material (usually a type of concrete).
- Local Depression
- Specifies the level difference between the inlet opening and the channel when the inlet is depressed.
