RUSLE2 Demystified – Workshop 1 of 3: Understanding RUSLE2 - Foundations for Defensible Erosion Modeling

Melanie Sotelo | Associate Vice President & Director of Environmental Service| Casc Engineering and Consulting

Level: Intermediate

Duration: 1.25 hour

Type of Course: On - Demand

PDH credits: 1

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.

Learning Outcomes.

• Explain the physical processes of soil erosion represented within RUSLE2.
• Describe the primary factors influencing erosion prediction, including rainfall erosivity, soil erodibility, topography, vegetative cover, and management practices.
• Identify the regulatory drivers supporting the use of RUSLE2 for erosion prediction and compliance.
• Explain how RUSLE2 estimates average annual soil loss and sediment delivery.
• Recognize the capabilities and limitations of RUSLE2 when evaluating erosion control alternatives.

Living with erosion: new approaches to managing erosion of rivers and coasts

Ian Rutherfurd | Professor |University of Melbourne, Alluvium Consulting

Level: Intermediate

Duration: 1 hour

Type of Course: Webinar – On Demand

Geomorphologists love erosion because it is a basic process in natural landscapes, but humans struggle to live with dynamic rivers and coasts, and there are many good reasons to stop erosion.  However, managers are moving away from the view that all erosion of rivers and coasts is bad, and has to be controlled, toward a more nuanced approach.  Sometimes the answer is not to control the erosion at all (e.g. the erosion is doing good, you make the problem worse, it is futile, it is a distraction from the real problem, and more), but sometimes to use land-use planning tools to give the rivers and coasts space to move.  More and more we are accepting that vegetation is the key to long-term, sustainable management of erosion (nature-based solutions) but this just slows the rate of the erosion rather than eliminating it.  I conclude by identifying some situations where  we should control erosion when we don't (e.g. it can make flooding worse).  In short, there are many reasons for us to learn to live with erosion.

Retrofitting Stormwater Basins for Water Quality                                                                                                                                     

 

Presenter: Jamie McCutchen | President - Rymar Waterworks Innovations

Level: Intermediate

Duration: 1 hour

Type of Course: Webinar - On-Demand 

Date: October 15th, 2026 @ 12:00pm MST

Summary: Many stormwater basins were constructed prior to water quality requirements and it is often not feasible to retrofit them to provide water quality using traditional methods because it requires a larger pond volume. This presentation will introduce a new method to retrofit basins to provide water quality that does not require the pond volume to be increased.

Retrofitting existing basins to provide water quality is often not feasible due to need for increased pond volume. However, a new method of providing water quality allows the current peak flows to be maintained, therefore not requiring a larger pond volume and has been tested to show 90% TSS removal. This presentation will explain how this new method can be effective to retrofit existing basins.

Understanding the benefits of sustainable fertilizers is critical to improving soil health and enhancing plant resilience to biotic and abiotic stresses, including heat and drought conditions. Many field water sources currently have high salinity levels, which can lead to soil compaction and poor growing conditions. Nrgizer helps improve plant tolerance to salinity, supports healthier soil structure, and enhances seed germination.

Rethinking Trackout Control: Modern Approaches to Construction Exit Management

Chloe Moretz - FODS Trackout Control Mats

Level: Intermediate

Duration: 1 hour

Type of Course: Webinar - On-Demand 

Trackout control remains one of the most persistent compliance challenges on construction sites, yet many of the industry’s standard practices have not kept pace with evolving regulatory expectations and available technologies. While rock construction entrances continue to be the most commonly used method, they are increasingly scrutinized for their limited effectiveness, high maintenance demands, and environmental impact. As a result, many construction teams rely on approaches that are both costly and insufficient for today’s performance standards. Despite this growing concern, there is still a significant knowledge gap surrounding modern alternatives to traditional rock entrances. Many practitioners are unaware of the full range of construction exit best management practices (BMPs) now available, including reusable synthetic trackout mats, wheel washes, and steel grate systems. There are also educational voids in how these options compare in terms of cost, durability, environmental performance, and regulatory compliance. This presentation aims to fill those gaps by offering a comprehensive look at modern, evidence-based methods for construction exit management. By examining the strengths and limitations of various BMPs and presenting real-world insights into system selection and implementation, the session will equip attendees with the information needed to reduce sediment tracking, streamline operations, and improve compliance outcomes. Ultimately, the goal is to support a shift toward more efficient, sustainable, and cost-effective trackout control practices across the construction industry.

This presentation examines why traditional rock construction entrances are becoming less effective and increasingly difficult to maintain under modern regulatory and environmental demands. It introduces a range of alternative construction exit BMPs, including reusable synthetic trackout mats, wheel washes, and steel grate systems. Attendees will learn how these modern solutions compare in performance, cost, and sustainability, and how to select the right system for their site conditions. The session ultimately aims to help construction professionals improve compliance, reduce sediment tracking, and adopt more efficient and environmentally responsible trackout control practices.

CLIMATE RESILIENT RURAL AND LOW-VOLUME ROADS

Gordon Keller | Geotechnical Engineer, GENESEE GEOTECHNICAL

Level: Intermediate

Duration: 1 hour

Type of Course: Webinar - On-Demand 

Climate-related storms and fires cause a great deal of damage to roads and rural infrastructure, causing erosion, damage, delaus and social impacts, and expensive repairs. Application of "best engineering practices" and climate resilience measures can reduce or prevent a lot of damage from weather related events.

Low-volume roads and rural infrastructure suffer an increasing amount of damage today from climate-change related impacts from storms, flooding, droughts, and fires. Often damage is caused or increased by poor construction practices, lack of drainage control, over-steepened slopes, and lack of application of "best engineering practices". Additionally, damage can be reduced or avoided by specific climate resilience measures including adequate surface drainage measures, appropriately sized drainage structures, use of "stream simulation" designs, cost- effective slope stabilization techniques, hardened road surfaces, etc. Many "storm-proofing" measures are relatively easy to implement and are very cost-effective, particularly given the high cost of repairs today. General "Best Engineering Practices" and specific resiliency, climate adaptation, or vulnerability reduction measures will be presented.

Rethinking Rubbish: Innovation on the Frontlines of Pollution

Heidi Tait |CEO and Founder Tangaroa Blue Foundation

Level: Intermediate

Duration: 1 hour

Type of Course: Webinar – On Demand

From nurdles and swarf to security tags, plastic strapping, and faded hi-vis scraps—everyday materials are quietly escaping our worksites, supply chains, and stormwater systems. Once they leave our hands, they don’t just vanish—they travel. They move through gutters, drains, and rivers, and eventually join a much bigger story of ocean pollution.

In this webinar, Heidi Tait—CEO and founder of the Tangaroa Blue Foundation and driving force behind the Australian Marine Debris Initiative (AMDI)—reveals what two decades of national data tell us about where pollution really begins, and how smart design, site practices, and stewardship can stop it before it starts.

From turning recovered fishing line into new sunglasses to partnering with councils on stormwater trap programs, Heidi shares surprising case studies that connect land-based decisions to ocean outcomes. You’ll see how construction sites, councils, and industries are leading change by rethinking waste, closing the loop, and collaborating across boundaries.

This session will challenge you to look beyond the clean-up and ask: What’s leaking from my site, my system, or my sector—and how can we design it out for good?

Stream Diversion Tactics for Good Stewardship

Adam Lyman, PE, CPESC, CEO, Syman Inc.

Date: Wednesday 7th October 2026

Time: 11.45am 1.00pm PST

Level: Intermediate

Duration: 1.25 hour

Type of Course: Webinar – Live

PDH credits: 1

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.

Learning Outcomes.

• Understand the information needed to plan a stream diversion
• Fill your toolbox with common diversion techniques
• Learn critical checks to ensure the diversion will be successful
