Column Headings Description
Lateral Inv. #2
This column contains the invert elevation at the pipes discharge point run for the second
lateral invert. If a valid lateral run name is entered in the Lateral Name #2 column, this
value is automatically calculated.
Lateral Name #1
This column contains the name of the first lateral run. The Pipes Run Editor searches for the
.mdb file with the lateral run name, and if it retrieves the lateral run file, the discharge flow
and invert elevation are imported.
Lateral Name #2
This column contains the name of the second lateral run. The Pipes Run Editor searches for
the .mdb file with the lateral run name, and if it retrieves the lateral run file, the discharge
flow and invert elevation are imported.
Node Drop
This column contains the node drop value, which represents the distance of the drop
through the node structure. Modifying the node drop value changes the nodes invert out
value and forces an automatic update of all downstream invert values.
Node Label
This column contains the node label for each upstream node in the pipe run. Each node
can have a unique name, such as MH1, MH2, and MH3.
North
This column contains the northing value of the nodes location point in the pipe run.
Offset
This column contains the offset value of the nodes location point relative to the current
alignment. If there is no currently referenced alignment, this column is left blank.
Pipe Descr.
This column contains the pipe material description, which you can edit.
Pipe Drop
This column contains the pipe drop value, which the Pipes Run Editor automatically
calculates by multiplying the pipe slope by the pipe length.
Pipe Flow
This column contains the pipe flow value associated with the pipe segment.
Pipe Label
This column contains the pipe label name for each segment of the pipe run. The pipe run
segment occurs between the node in the same row as the pipe label in the Pipes Run
Editor, and the node in the next row down. Each pipe run segment can have a unique
label. For example, you can designate the segment between MH3 and MH4 with the label
3-4.
Pipe Size
This column contains the pipe size. You can enter any pipe size in this column; however,
only pipe sizes that are defined in the Pipe Slope Control Table can be automatically sized
based on flow. If the pipe diameter is too small for the design flow, the Pipes Run Editor
automatically selects the next available size that meets the design flow requirements.
Pipe Slope
This column contains the pipe slope value, entered as ft/ft or m/m. For example, enter the
value, 0.02, for a pipe slope of 2 %. When you change the pipe slope value, the Pipes Run
Editor automatically recalculates the value for the finish invert elevation for the pipe
segment, as well as all of the downstream invert elevations.
Rim Elev.
This column contains the rim elevation of the node. Once you define the run, modifying
the nodes rim elevation does not affect the inverts in or out.
Rough Coeff
This column contains the roughness coefficient value for the pipe segment for use in flow
calculations, which you can edit. The roughness coefficient used depends on which
formula and method you use for pipe flow calculations: Manning, Darcy-Weisbach, or
Hazen-Williams. You can either enter a roughness coefficient value, or place your cursor in
the Rough Coeff column and click Edit to open the appropriate Coefficient Table dialog
box.
