    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”.

    Geyserville Highway Bridge used these methods

    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.

    BIOENGINEERING WEBINAR at IECA Learner Community

    Here is a picture of my Grandpa John McCullah and his brother Ed BIOENGINEERING the eroding banks of the Kings River, near Hanford CA, back in the 1910s !!  

    Also look at the second picture of them "checking out their work during the floods.  That is a sign of a "good practitioner", one who visits the site during storms to see what can be improved upon.


     

    At that time, little did my granpa know I'd be doing similar work a 100-years in the furture. This type of construction for slope and streambank stabilization is keenly intersting to me.  I have been designing and implementing projects with these methods for over 20 years now.  I started with the willow "live" stake, then did everything with the "willow wattle".  By the way, do you know where the term STRAW WATTLE originated ?

    Later I became interested in "Live Brush Layering".  This webinar really covers the key priciples and concepts about BIOTECHNICAL SOIL STABILIZATION that I have learned over the last 20-years.

    I have built projects using these naturally-occuring and sustainable methods in Canada, Alaska, California, Kansas, Malaysia, and New Zealand.  Learn more about Bioengineering, where and how did these evolve.

    Repairing a huge landslide (the "Big Sandy") in Seschelt BC back in 1999.  Using Willow Wattles and Brush-Layered Toe Wall.

     

    Did you know that Caltrans published a Manual in 1950, which detailed the use of brushlayering and willow "wattles" for building highway embankments and fill slopes.

     

     

    This highway manual was preceeded by the work of Charles Krabel, circa 1937, Landscape Architect for Forset Service in So. California.

     

     

     

     

    Learn some of the history of Bioengineering in the west.

     

    How do you build fill slope embankments steeper that the angle of repose?  Engineering principles say to mechnanically reinforce.  Learn how to combine naturally-growing materials into your desigm, biologic materials that CAN continue to grow soil reinforcing roots that help not only stabilize but also reduce pore pressure on wet slopes!

     

    This Webinar will also discuss topics in Natural Succession and the value of "mimicing" natural systems.

    This program is a must for those of you who are challenged to knowlegably offer justifications for adding bioengineering compontnets to your projects.  Also a "must" for those who want to see case studies that describe successes (and some failures) on projects that have survived the test of time.

    This webinar will be super interesting to those of you already familiar with Bioengineering but it is also intended to give you a huge "first step" into BIOENGINEERING and BIOTECHNICAL TECHNIQUES for SLOPES and STREAM BANKS.

    Hopefully you interest is piqued.  Sign up for the Webinar now and also Professional Development Units.

    BMPs Demonstrated at Summit provide ideas for Slide/Slope Failure Repair

    Redding received over 10" of much needed rain in January.  But all that rain and the saturated soils led to a small slope failure on the Palisades Trail.  You may remember the way we treated the "seeping" slopes two years back, with 2" compost, native grass, mycorrhizae, all reinforced in Enka Mat and then sprayed with Flexterra (known as Green Armor System) Palisades Trail update

    Well, we learned a few things at the last couple of Shasta College Summits, including some innovative uses for Compost Socks and how to use and install the Gripple Anchor System.  When Terry Hanson called and said there was a small landslide above the trail.  He informed us he had a CCC crew scheduled, very little budget, and another batch of storms were expects.  Dis we have any ideas, and could we provide a prescription. The College had some products remaining from the Summits we could probably donate, primarily in the form of Filtrexx Compost Siltsoxx and Filtrexx Compost Grosoxx and some Biaxial geogrid.  Terry had some 2010 Enka Mat.  Our prescription was to excavate the heavy failed clay material as feasible and then pack the slide face with Compost Socks.  The sock would be enveloped in Enka Mat and Geogrid and then anchored to the slope.  We decided to use the new Gripple Anchors (altogether we used about 45 anchors) system to anchor the materials to the slope and counter the outward forces.

    It was fortunate that we had both green Siltsoxx (more designed for filtration) and the Grosoxx which are designed with more of a growing medium.  Since the slide area is still draining, the green socks may aide drainage while the black growsox may do a better job growing native grasses.  We will get to follow the project through time. 

    PHOTOS WILL BE POSTED SOON
