Drainage Network Workflow

General Workflow

• Add drainage network to create initial design based on a road; or build a network with structures apart from a road.
• Make adjustments and additions to the design (see detailed workflow, below)
• Size drainage network to fine-tune the design after making changes. Use Highlight Drainage Network to see the full extent of a network if you have connected structures apart from a component road layout.
• Inspect performance of pipe runs and analyze surface drainage between inlets.

Important points to keep in mind:

• Once you are satisfied with the layout of a drainage network, run Size Drainage Network. It recalculates pipe diameters and adjusts their slopes to accommodate your changes. It also resizes connectors if pipe sizes change.
• Before you can run Inspect Performance, you first need to run Size Drainage Network.
• Inlet Analysis and Inspect Performance work only on structures located within the geometry of the selected component road.
  • For example: if an outfall connects to a manhole located in an intersection adjacent to a component road, you cannot run Inspect Performance. Consider moving the outfall to a manhole within the geometry of the component road. Then use Size Drainage Network.

Detailed Workflow

After adding a pavement drainage network, you can modify the initial design components in whichever order you like. Then run Size Drainage Network.

Action	Notes
Add Drainage Network	From a road's context menu, the tool adds structures along the extent of the selected road. Note the tool adds structures only to road assemblies or styles with curbs. By contrast, the (Drainage Network) tool add structures one or a few at a time, anywhere you place them. You can choose structures from the default component part catalog or from a custom catalog, using Infrastructure Content Authoring.
Move outfalls	Select outfall in edit mode, use transform gizmos to change its position, rotation, height, and elevation.
Relocate inlets	In-canvas.
Re-arrange pipe connections	In-canvas.
Change pipe material	In-canvas. Use component part catalog selection panel.
Size Drainage Network	resizes the structures connected to a single, selected network. Use , Highlight Drainage Network. to see the extents of the network. Size Drainage Network, on the selected road's context menu, re-sizes structures connected to all networks along the road. This scope may be larger than you need to work with.
Analyze design	Inlet Analysis: In-canvas: visually inspect inlet capture, spread, and bypass. Data re-calculates in real time, as you change location of inlets. On stack panel: see inlet efficiency rating (percent) and related data. Inspect Performance: in canvas, see hydraulic and energy grade-lines; detect surcharged pipes and flooded manholes. Adjust AEP setting prior to starting an analysis to model performance in different storm level conditions.
Delete and add a new a Drainage Network	After Major Changes to a Road, Delete Previous Network, Add New One. If significant changes are made to a road with a drainage network, delete the existing drainage network rather than work with it. Add a new drainage network to the revised component road; run Size Drainage Network.
