Class Summary
This class will explain how Civil 3D® and the new Storm and Sanitary application help with the design and evaluation of natural channels and stormwater management facilities. Attendees will learn how to import and integrate GIS data into AutoCAD® Map 3D, create custom assemblies in Civil 3D® for natural channel design, and develop existing and post-development hydrology in Storm and Sanitary Analysis.

Importance of Stream Restoration in the 21st Century
“At no other time in the history of modern man have the cumulative impacts associated with development along the river had a greater impact on water resource values.”

To Straighten or Not to Straighten
Common practice to straighten streams in urban and agricultural areas Studies show meandering reaches are more stable than straightened

Site Details: Weicher Creek
Tributary to South Fork Beargrass Creek in Jefferson County, KY BearGrass Creek Watershed drains ~ 70 square miles Humid climate Development upstream and downstream Flooding risk is very high Current channelization of the creek and problems with urban runoff compromise water and habitat quality.

Importance of Targets
Stream Parameters change constantly. Targets are key for the best possible design.
Targets reference other linework and override defaults For Width: alignments, polylines, , or survey figures For Elevation: profiles, 3D polylines, , or survey figures

AutoCAD® Civil 3D® Subassemblies
Three options when creating a Stream Assembly
Use “out-of-the-box” subassemblies Create a custom Subassembly using the Subassembly Composer Use Generic Links
How do you know which option to use?

Conclusion
Stream Design involves many inter-dependant relationships. Changing one geometric feature affects others. Use dynamic features of AutoCAD® Civil 3D, Autodesk® Storm and Sanitary Analysis, and River Analysis to continuously evaluate and modify parameters of the stream.
