The Important Role of Vegetation in Stormwater Management

Vegetation is Nature’s best management practice (BMP) for controlling erosion, yet when we discuss BMPs, we are often focused on structural practices that reduce erosion and/or remove sediment. This webinar will focus on the important role that vegetation plays in stormwater management during and after construction and will present new guidance developed in Colorado that covers many fundamentals of successful revegetation and could be adapted to other regions. Dr. Earles will discuss the different hydrologic, physical and biological processes that make vegetation an effective BMP. Students will leave the webinar with a renewed appreciation for vegetation and the key role it plays in effective stormwater management.

Turbidity Control by Chemical Flocculation: Basic Concepts

While the US EPA has withdrawn its proposed turbidity limit on construction site runoff, there are still many states have or are proposing their own enforcement levels. Construction site owners and managers are also looking for ways to avoid public outcry and potential lawsuits over muddy water leaving their site. In most cases, typical and even more advanced erosion and sediment control practices will not prevent discharges that look like chocolate milk. This two-part seminar will explore the principles behind chemical treatments to rapidly settle suspended solids and reduce turbidity in runoff from construction sites. In the first part, McLaughlin will discuss ways to make typical practices work much better and then explore the turbidity problem and how chemical treatment can solve it.

Working in Waterways

Projects that involve construction activities in waterways are some of the most challenging ones that engineers and contractors face. These projects often involve obtaining permits from multiple agencies, engineering of temporary diversion measures, and development of strategies for stormwater control measures in what is often a space-constrained environment.
