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
st
21
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, feature lines, or survey figures
For Elevation: profiles, 3D polylines, feature lines, or survey figures

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.
