2016 Erosion and Sediment Control Conference
31st August - 2nd September, Rydges Hotel, Auckland
Collaborate Innovate Motivate Participate
IECA and NZIHT hold this Conference every two years to bring their members, industry practitioners and stakeholders together in New Zealand. We hope to address how we get the industry to “Collaborate, Innovate, Motivate, Participate” and how we can improve in all these areas.

The Best of The BMPs, after over 25 years “in the trenches” John McCullah has some thoughts about construction activities, soil erosion and the BMPs used to prevent sediment pollution of our waters. As a contractor, a biologist and with a Bachelors in Watershed Geology/Hydrology, John was asked to draft his first “BMP Manual” for a rural municipality in 1991. This experience set the trajectory for his vocation/avocation - finding, describing, and teaching the most effective BMPs. During this brief presentation John will summarize the best approaches to erosion and sediment control, the physical processes involved, and then how to select and install BMPs to “Make them Best”. His presentation will include movie clips from the Dirt Time video series, experiences teaching Departments of Transportation, especially CALTrans, the art of selecting and implementing effective BMPs, and the operation of the Shasta College Erosion Control Training Facility. You will walk away with knowledge of what John calls, “the Big Four” - the most cost-effective erosion control BMPs.

Natural Stream Channel and Bank Protection. In 2005, John and Dr. Donald Gray published a 3-yr research report, NCHRP Report 544-Environmentally Sensitive Channel and Bank Protection Methods. The research was commissioned by the Transportation Research Board, comprised of the State DOTs members. The problem statement: Are there techniques that can be employed by Highway Engineers as alternatives to riprap (rock slope protection)? Highway Engineers in the US and Canada were having difficulty getting environmental clearances (permits) for projects adjacent to rivers and streams. John and Dr. Gray won the research because of their expertise in fluvio-geomorphology, geotechnical engineering and bio-engineering. The published report, including design guidelines, Cad drawing etc., documented over 50 environmentally-sensitive methods. Especially informative is the guidance for re-directive methods such as Rock Vanes and Bendway Weirs. John will introduce the report and present case studies on how these practices have been successfully used by him in the US, Canada, Malaysia and New Zealand (Lucas Creek). This presentation is a precursor to some Masters Courses John will be teaching the following week in Auckland and Christchurch
