In 1992, the Environmental Protection Agency (EPA) stated that construction sites must have sediment containment systems (SCSs) with sufficient volume that can capture the runoff from a 2-year, 24-hour stream event creating 3 inches of precipitation…resulting in 1-inch or approximately 3,600 ft.3/acre of runoff. Unfortunately, 3,600 ft.3/acre only occurs for sandy soil conditions. What about the rest…is this enough?
Join returning speakers Jerald Fifield and Tina Wills as they explore this question, as well as the design best practices, techniques, computations, and analysis in designing effective construction site sediment containment systems.
This webinar will be available live on Thursday, September 17th, 11:00 a.m. – 12:30 p.m. PDT / 2:00 p.m. – 3:30 p.m. EDT, and available on-demand after the live event. Register for the event by clicking the button below.
In this webinar, we’ll explore the two most commonly misused parameters in the design and review of sediment basins and traps – containment surface area and volume, why the capture of 3,600 ft.3/acre may not be enough, and the parameters designers and reviewers need to incorporate into their sediment containment system design and review. Within this discussion, we’ll explore the basics of sediment containment systems, how suspended particles are captured, and the effective use of polymers within design. Additionally Fifield and Wills will outline the techniques, equations, and computations necessary in designing effective sediment containment systems, and how you can apply these to your designs and/or review. And finally, we’ll discuss how to properly analyze and evaluate sediment containment system effectiveness during flood flow conditions.
Attendees can expect the discussion and education of the following learning objectives.
- Understanding of the types of sediment containment systems and effective outlet structures
- Understanding of why designers and reviewers must develop SCS for design flood flow events
- Application of scientific and engineering methods on developing parameters
- Understanding of how use of polymers can increase the effectiveness of an SCS
