Repairing Entrenched and Degraded (Urbanized) Streams – Techniques and Case Studies

This class is a must for Engineers, Hydrologists, Planners, and Ecologists who are challenged with Urban Stream “greening”, highway repair, and channel restoration. Join these experienced project designers and builders to see what has worked and what not.  The training will be fast and fluid, using case studies, Dirt Time movie clips and extensive use of Case Studies.  Guidance documents, including the NCHRP Report 544 – Environmentally Sensitive Channel and Bank Protection Methods on CD, will be provided for free.
This course is really interesting.The material will be presented with the extensive use of Case Studies.  John McCullah will present projects utilizing Bioengineering and Environmentally-Sensitive techniques from US, and Canada, to New Zealand, some spanning over 15 years.  Case studies will be enhanced with the use of Dirt Time video clips.
John will present information that will be exceptionally relevant to the Pacific Northwest where endangered salmonid species and the associated life stage habitats are of concern.   As a watershed restorationist and design/ build contractor John will show how special construction techniques, combined with these “self-mitigating habitat enhancing methods” can build projects; 1. Without requiring costly river diversions/isolation techniques, 2. Without excessive destruction of the stream banks and channel bottoms, 3. Using designs that include appropriate bioengineering methods to ensure maximum geotechnical and habitat enhancements, and 4. With little to no downstream increases in turbidity!

Attendees will learn about “thalweg management”, an approach to natural river design that looks at the vectors of high velocity during large flows, not just the average channel velocities or shear.  And you will learn about the environmentally–sensitive redirective techniques, such as Rock Vanes and Bendway Weirs, which can be employed to “manage the thalweg”.  Redirective methods, using well graded stone and a wide array of bioengineering have been used successfully for decades throughout the US.  Similarly, John has designed and built projects in ecologically sensitive streams throughout California, Canada and New Zealand.  John will present relevant project case studies to show “the proof’s in the pudding”.

Besides the Case Studies showcasing these methods you will also recieve Design Specs and Detailed Drawing for :

1. Newbury Engineered Riffles (environmentally sensitive grade control)

2.  Rock Vanes

3. Self-Launching Stone - Clean well-graded self-adjusting, well-graded stone that precludes the need to dig in the channel (scour trenches no longer needed!)

4.  Longitudinal Stone Toe combined with willow Live Siltation - the most cost effective method so far!!

5.  No longer do you have to dewater or divert stream to protect water quality

6.  Bendway Wiers - learn how to redirect the "high, impinging flows" away from the bank to reduce the need for thick riprap armoring.

7.  Vegetated Riprap, Vegetated Gabions, Vegetated Large Woody Debris if you must install revetments!

8.  And so much more.
