On the Takitimu North Link Project there is a complex set of stream diversion and culvert installation works being undertaken which have provided numerous erosion and sediment control challenges. A new stream channel is being diverted adjacent to an existing closed out landfill. However, it was discovered that there was a large volume of rubbish outside the footprint of the leachate line which turned a straight forward stream diversion into a complex contaminated land remediation exercise whilst working beneath the water table and within large volumes of leachate runoff.

The objective of this class is to review and gain an understanding of the RUSLE calculation (Revised Universal Soil Loss Equation, and its impact on sediment and erosion control in the construction industry.

Steve Polk and Ted Hartsig team for this Two Session program that will inform attendees about existing knowledge gaps that are plaguing designers and contractors of post-construction stormwater BMPs/SCMs. During professional careers spanning more than 40 years, Polk and Hartsig have seen far too many projects badly because key participants in the stormwater compliance industry still doesn't "know what they don't know," and in many cases "don't have the time" to investigate. During this program, Steve and Ted will inform you about some of the most frequent problems that drive teams to an unfulfilling project results.

Join Aaron Harper and Donald Pearson as they share four decades of experience highlighting the significance of groundcover and vegetation in linear construction, particularly from the Piedmont to the Coast of North Carolina.

Join our webinar on "Regenerative Ecological Fitness in Erosion Control" to explore how integrating Indigenous wisdom and sustainable practices can transform erosion control into a cost-saving and ecologically beneficial strategy. Learn from Townsville's success in creating its own SESC products and services, showcasing practical applications and new business opportunities that enhance ecosystem resilience and reduce costs.

This presentation will focus on utilizing Composite Bentonite Aggregate (CBA) technology to provide cost effective solutions that address water seepage and erosion. Functional use in both civil and geotechnical applications will be reviewed.

Since 2001, GTC has used “shredded” wood material generated from tree clearing activities to immediately stabilize transmission line rights of way. The shredded wood material degrades in a mosaic pattern which extends protection from erosion and sedimentation as vegetation re-establishes.

Increased rainfall intensity with climate change is being incorporated into design rainfalls and runoff guidelines which can be used for erosion and sediment management on construction sites. Erosion and sediment controls are beneficial for construction sites impacted by increases in high intensity rainfall events to meet legislative requirements and reduce the burden on sediment basins.

This webinar will present many of the practical and cost-effective climate resilient measures that can be implemented for roads to adapt to climate change. Emphasis is given to needed drainage and road-stream crossings measures useful to reduce the risk of storm damage.

Flocculants are powerful tools that have been used for decades to control erosion, stabilize soil, and remove harmful contaminants from water. Flocculant treatments can meet very low discharge limits, allowing sites to stay in compliance, meet regulations and improve stormwater quality and clarity. Applied Polymer Systems introduced flocculants to the erosion and stormwater industries in the 1990s, drawing from decades of research and use in mining effluent treatment. Anionic polyacrylamide is the most widely accepted and commonly used flocculant due to being both safe for aquatic life, and highly effective.

This webinar will celebrate and showcase the Australasian Chapter's Environmental Excellence Award winners for 2023. Bruce Highway, Cairns Southern Access Corridor (Stage 3) - Edmonton to Gordonvale Project (E2G) - AND - NIWA Weather Forecasting – A New Zealand First in the Construction Industry.

Regulation without enforcement is an issue in all areas of law. We will explore the water quality effects of enforcement. using relavant case studies from both the state and local level.

This webinar will examine the basic principles of stream erosion and the various practices that are utilized to address and repair stream bank and bed erosion in the upper Midwest.
