This session covers the next generation of drainage design and analysis tools integrated directly into Civil 3D, leveraging the InfoDrainage calculation engine for in-product hydraulic workflows.
Key Features & Drainage Objects
-
Analyze Drainage System: A native Civil 3D analysis command powered by the InfoDrainage engine. Runs SWIM-based dynamic wave calculations without requiring external software like SSA.
-
New Drainage Objects:
-
Ponds: Create simple ponds with custom side slopes and shelves, or generate detailed pond objects directly from surface contours. Extract feature lines for full grading control.
-
Underground Storage: Define chamber footprints, depth, and volume, with support for importing vendor storage tables (depth-vs-volume data).
-
Channels: Build channels using feature lines or alignments/profiles. Customize cross-sections via standard geometric shapes or directly attach Civil 3D assembly link codes.
-
-
Catchment & Runoff Updates: Added support for SCS, CPA SWMM, Santa Barbara, and Rational/Modified Rational runoff methods alongside updated Time of Concentration calculations.
-
Rainfall Management: Configure IDF curves, distribution-based rainfall, or custom time-increment rainfall data directly inside Civil 3D.
-
Outflow & Infiltration Controls: Define complex outlet structures including orifices, hydro-brakes, weirs, and bottom/side infiltration rates.
