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

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.

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 River Analysis

Learning Objectives At the end of this class, you will be able to: Develop a workflow for stream restoration Identify constraints and provide preliminary site assessments using Map 3D Utilize Storm and Sanitary Analysis to determine impacts on bankfull and flood discharges Evaluate stream corridor design scenarios Utilize River Analysis to determine cross sections and HEC RAS analysis (Bonus Material)

Class Expectations General Workflow to resolve project-specific issues for stream restoration projects Intermediate level class Need basic knowledge in creating surfaces, alignments, profiles, and corridors Please Silence Cell Phones Please Hold Questions x x

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

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 GOOD BAD The Nature Conservancy - Big Darby Creek Headwaters Restoration Project http://www.nature.org/ The Nature Conservancy - Big Darby Creek Headwaters Restoration Project http://www.nature.org/

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 feature lines feature lines

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? HELP MENU

Subassembly Composer Provides an interface for composing and modifying complex subassemblies, without programming Suggested AU 2011 Classes CI4252 Create Subassemblies That Think Outside the Box with Subassembly Composer Dec 1 2011 3 pm CI4264 Music for Your Brain: Advanced Lessons in the Subassembly Composer Dec 1 2011 5pm

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. FIND THE BEST RESULTS
