Model a drainage network, including outfalls, using analysis-driven design and spacing rules. Create an draft design based on a design road or building out a network with structures apart from a road. Refine and re-size network structures. Manage rainfall content data and analyze inlets and inspect hydraulic performance of selected pipe runs. Generate a table showing quantities of materials needed.
Two ways to build a drainage network:
- Use
Add Drainage Network, the right-click menu design road tool, add an initial, draft drainage layout for the selected design or component road. Adjust the drainage structures and materials, including outfalls, as needed.
Note: Inlets are placed only if the selected road uses a road style with a Curb track.
- Use
,
Drainage Network, to create a network anywhere, apart from a road. Add pipes, inlets, manholes or outfalls, one or a few at a time. You can connect these structures to a design-road based network.
Or:
You choose component part structures from a part catalog, which can be shared with Autodesk AutoCAD Civil 3D. Drainage Design supplies a default catalog. Using Project Kameleon (Preview), you can create a custom component part catalog.
-
resizes the structures connected to a single network, including a network apart from a design road. Use Highlight Drainage Network to see a network's extents.
- The design (or component) road version, located on the selected design road's right click menu, re-sizes structures connected to all networks along the road.
Analysis-Driven Design and Sizing of Structures
Drainage Design uses industry standard rules and calculations to provide analysis-driven design. These data and standards include watershed flow data, Rational Runoff calculations, Road Slopes/Manning's coefficients, and Intensity-Duration-Frequency (IDF) Rainfall coefficients. You can vary the AEP setting (default = 1/10) to examine pipe runs in different storm level conditions. You can override Drainage Design decisions to suit the needs of your model. You see these data in-canvas or on a drainage structure's asset card.
Manage Rainfall Content Data
Using
,
Rainfall content, you can assign model-specific rainfall data for more accurate drainage design. It provides you with three, pre-defined sample content templates, which you can customize: BDE, Tabular, and ANZ.Polynomial (used in Australia and New Zealand).
Quantities of Materials Needed
For a selected design road with a pavement drainage network, use
, the Quantities tool to generate a list showing quantities of culverts, inlets, manholes, pipelines and outfalls.
