Erosion control practitioners are often called upon to work below the ordinary high water to complete projects in the areas regulated by the army corps of engineers. There is volumes of manuals for geomorphology and successful stream restoration and revegetation, and there is a depth of engineering manuals for large water bodies to install coffer cells and work off of barges. However the guidance on temporary works to divert small rivers, creeks and streams before and during construction begins is difficult to find. This presentation aims to fill some of that gap with strategies for working in live streams on the small or mid-size project that requires modification to the stream bed.

Accurate prediction of soil erosion is a critical component of erosion and sediment control planning, stormwater compliance, and construction project design. RUSLE2 (Revised Universal Soil Loss Equation Version 2) has become the preferred erosion prediction model for numerous transportation, infrastructure, and regulatory applications, including compliance with portions of California's Construction General Permit and certain Total Maximum Daily Load (TMDL) requirements. Despite its widespread use, many engineers and environmental professionals rely on RUSLE2 without fully understanding the scientific principles, assumptions, limitations, and regulatory context underlying the model. This webinar provides a technical foundation for understanding how RUSLE2 estimates soil loss, when it should be applied, and how it supports defensible erosion prediction and compliance decisions.

This webinar will provide the essential background understanding that SWPPP Developers and Practitioners to understand and navigate these updated requirements. Attendees will learn about the requirements for dewatering and passive treatment systems and how to track the weather forecasts to identify a Qualified Precipitation Event (QPE). This timely webinar offers practical guidance to adapt stormwater management strategies in light of the new permit requirements, in pursuit of improved water quality outcomes.

Detention is an extremely important factor in flood management, it is also expensive, yet we use flow control technology that is hundreds of years old to size and manage these systems. The reason? Designers are not aware that there are viable alternatives that are easy to use and very effective at optimizing detention systems. This presentation will highlight alternative flow controls that employ vortex flow control system and case study projects that have gained significant benefits from the use of these advanced passive controls, including significant cost reductions.

Traditional stormwater inspections are often time-consuming and inefficient, leading to compliance risks, costly delays, and regulatory penalties. This session will explore how AI and automation can streamline compliance workflows, reducing errors and improving efficiency. Stormwater and erosion control expert Jessica Acosta will break down the challenges of manual inspections and introduce AI-driven solutions designed to enhance accuracy and simplify compliance. Attendees will gain actionable insights on integrating digital tools into their existing workflows, ensuring smoother operations and regulatory adherence.

Since being awarded the IECA educational award in 2022, the On-Country Soil Erosion and Sediment Control training has continued to deliver unique and geographically experiences across Queensland. The training has offered a safe, inclusive, and experiential learning base for its attendees that not only expanded upon the best practice principals and techniques from IECA but exposes all participants to landscape and cultural insights only available when leaving the classroom and walking Country. Shared and integrated knowledge of air, water, soil, vegetation, and people. The content delivery on Country takes an empowering shift away from a teacher to pupil model and embraced a collaborative and adaptive approach. This presentation will talk through our recent presentations, learnings and the next steps for the program.

Water quality and detention are becoming increasingly necessary to ensure the health and safety of our communities. Texas has beautiful and unique natural environments which include endemic and endangered species, parks, lakes and spring fed rivers that are used for recreation. With Texas growing at a substantial rate, it is imperative that we prevent pollution for our community and environment. The City of San Marcos developed a routine inspection program for permanent stormwater detention and water quality controls. If these controls are operating as designed, they will improve water quality in our waterbodies and help decrease flash flooding.

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. Anionic polyacrylamide is the most widely accepted and commonly used flocculant due to being safe for aquatic life, and highly effective, and extremely versatile. This webinar will explore the benefits of aPAM technologies, approval and current use in New Zealand, as well as future usage in the region.

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.

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.
