1. 3-in-1 Stream Restoration Using AutoCAD® Civil 3D®, Map 3D, and Autodesk® Storm and Sanitary Analysis
Heather Nagel
Application Engineer

2. 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.

3. Exciting Change to Class
3-in-1 Stream Restoration
AutoCAD® Civil 3D®
AutoCAD® Map 3D
Autodesk® Storm and Sanitary Analysis
4-in-1 Stream Restoration

6. 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.”
Dave Rosgen, Applied River Morphology

7. 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

8. 4 in 1 Workflow for Streams
Build Basemap
Build Existing Data
Run Existing Hydrological and Hydraulical Analysis
Create Proposed Design
Run Proposed Analysis
Compare Data
Modify Design and Repeat Steps as needed

9. 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.

18. 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

19. 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?

22. FIND THE BEST RESULTS 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.
