About Drainage Design

Use Drainage Design for InfraWorks to model watersheds, culverts, and drainage networks. Apply rainfall content data to analysis-driven designs. Review and analyze performance of individual drainage structures or sections of a drainage network. Run flood simulation animations for coastal or inland scenarios. Choose pipes and connectors from a default or custom component part catalog, which Drainage Design can share with Autodesk Civil 3D.

Watersheds

• Identify and analyze watersheds and stream flows.

Drainage Networks

• Work with rainfall content data to create a more precise drainage network design.
• Add a Drainage Network layout to a selected component road.
• Place pipes, inlets, manholes, outfalls or combinations one at a time and modify drainage network features.
• Highlight Drainage Network shows you the full extent of a network connected to any structure in it you select.
• Run Size Drainage Networks tool to fine-tune pipe diameters, slopes, and underground structures. This tool uses criteria for operating at full-flow capacity. Use it after you have adjusted the draft design.
• Delete drainage structures or an entire network if the road changes significantly.

Culverts

• Add a culvert manually.
• Modify culvert size or placement.

Flood Simulation

• Prepare a flood simulation.
• Run a flood simulation animation in-canvas.
• Create a flood snapshot.

Analysis-driven Drainage Design and Tools

Drainage Design for InfraWorks applies analysis-driven design rules based on industry standards for structure size, material, and placement. For example, Drainage Design Analysis responds to component roads contextual placement, slope, and materials. Analysis of inlet location, tributary area, gutter spread and inlet performance utilizes both the component materials (which may have different runoff coefficients) and cross-slopes to adjust an inlet's placement and slope for best solution in storm conditions.

You can see the key data used for these design rules in-canvas or on the stack . You can change design decisions to suit your model's needs, making changes either in-canvas or by editing attributes on the stack. You can also select different parts from the component part catalog.

Analysis tools enable you to analyze and inspect the performance of key drainage structures in your model:

• Inlet analysis enables you to check surface drainage performance between two inlets, simply by selecting an inlet. The tool responds to changes in real time.
• Inspect Performance displays data and a visualization of a pipe's hydraulic and energy gradeline performance between two connectors. The tool identifies surcharged pipes and flooded manholes.

Pipe Connector Component Part Catalog and Autodesk Civil 3D

Drainage Design provides a default component part catalog for pipeline connectors (manholes, inlets, outfalls). This catalog is also available in Autodesk Civil 3D. If both applications use parts from this catalog, then, when you bring these objects back into InfraWorks from Civil 3D, InfraWorks can display them with realistic visualization and preserve Autodesk Civil 3D design work. (The utility type is set automatically for these drainage objects brought into Autodesk Civil 3D.)

Custom Component Part Catalogs using Infrastructure Parts Editor

Using the Infrastructure Parts Editor, you can create and publish a custom part catalog for use with the Add Pavement Drainage and Sketch Drainage Network tools. If you bring an InfraWorks model into Autodesk Civil 3D, custom drainage network parts will be recognized by Autodesk Civil 3D as Pipe Networks (Drainage) objects. See About the Parts Editor.
