ValleyChannelSimple

The ValleyChannelSimple subassembly is a concrete valley channel with user defined widths, concrete depths, and invert level depth. The width can be modified and the invert level stays at the center.

Attachment

The attachment point is at the inside edge of the valley channel.

Input Parameters

Note: Note: All dimensions are in metres or feet unless otherwise noted. All slopes are in run-over-rise form (for example, 4 : 1) unless indicated as a percent slope with a “%” sign.

Parameter	Description	Type	Default
Side	Specifies which side to place the subassembly.	Left/Right	Right
Concrete Width	Width of the concrete channel.	Numeric, positive	5 ft 1.5 m
Invert Level Depth	Depth of the valley channel from the top of the ditch to the invert level.	Numeric, positive	0.08 ft 0.02 m
Width1	Width of the valley channel on the side of the attachment point.	Numeric, positive	0.5 ft 0.15 m
Width2	Width of the valley channel on the opposite side of the attachment point.	Numeric, positive	0.5 ft 0.15 m
Concrete Depth	Depth of the concrete measured from the attachment point.	Numeric, positive	0.75 ft 0.2 m

Target Parameters

This section lists the parameters in this subassembly that can be mapped to one or more target objects. For more information, see To Specify Corridor Targets.

Parameter	Description	Status
Target Offset	May be used to override the fixed Width and tie the edge-of-shape to an offset aligning. The following object types can be used as targets for specifying this offset: alignments, polylines, features lines, or survey figures.	Optional
Invert Level Level	May be used to override the invert level depth and tie the invert level level to the level of a profile. The following object types can be used as targets for specifying this level: profiles, 3D polylines, feature lines, or survey figures.	Optional

Runtime Logical Assignments

None.

Output Parameters

None.

Behavior

This subassembly will insert a simple valley channel. The location of the width of the subassembly can be specified with a fixed width, or with an optional alignment. The valley channel can be specified with a fixed depth, or a profile can be assigned to control the depth.

Layout Mode Operation

In layout mode, the subassembly displays the links comprising the valley channel with the user input values.
