Workshop #1 May 30 8:30 am - 12 pm

Stream Restoration Structure Functions and Performance

Instructor: Dave Rosgen, PhD, Wildland Hydrology

Materials that students need to bring: open mind

Materials student will receive: power point copy

Learning Objectives:

At the completion of this workshop students will be able to:

1. Better understand what structures are designed for what processes

2. How to match materials with your stream and valley type

3.Understand the multiple objectives of structures

4.  Understand specific structure design details

5.  Understand the misuse of structures

6. Emphasize the importance of designing the correct dimension, pattern and profile that structures must be compatible with

7.  What can go wrong-common mistakes

8.  How to create more natural “Natural Channel Designs” with appropriate structures

Workshop Description: Detailed design will be presented, appropriate and inappropriate application of structures.  Lessons learned from common mistakes.  Need to be sure the structures are compatible with the correct morphological parameters.  The real objectives of structures and the correct design and placement to ensure the opportunity to buy time for vegetation establishment, flow energy dissipation, fish habitat enhancement, sediment transport, near-bank stress reduction on streambanks, grade control, recreational boating, etc.
