Pipe Table

The Pipe Table provides bulk editing of Manning's n values across all pipes in the network.

Opening the Pipe Table

Open the Pipe Table from Tables menu > Pipe....

Layout

The Pipe Table is a DataGrid grouped by alignment. Each group header shows the alignment name, and the pipes within that alignment are listed beneath it.

Column	Description
Pipe	Pipe name (read-only)
Manning's n	Manning's roughness coefficient (editable)
Edited	Flag indicating unsaved changes to that row

Bulk Apply

To set the same Manning's n value on multiple pipes at once:

1. Select the rows you want to update (use Ctrl+Click or Shift+Click for multi-select).
2. Enter a value in the "Bulk set Manning's n on selected rows" field.
3. Click Apply.

The bulk apply works across alignment groups, so you can select pipes from different alignments and set them all at once.

Workflow

Edit Manning's n values individually or via bulk apply, then click OK to apply changes to the working session. Changes are reflected immediately in the hydraulic calculations — you will see updated velocities, HGL, and capacity results as soon as the Pipe Table dialog closes.
