Hydromodification - Causes, Effects, and Mitigation

As professionals in erosion and sediment control we are often focused on on-site erosion and sediment controls. When considering changes in runoff rates and volumes, however, it is essential to look downstream of the site to understand how changes in hydrology may adversely affect downstream receiving waters from the standpoints of degradation, aggradation, and aquatic habitat. This presentation will focus on the causes and effects of hydromodification, the roles of peak flow rates and runoff/streamflow volume, and the fundamentals of mitigating these effects. The presentation will provide examples of strategies to mitigate impacts of hydromodofication including the importance of stormwater volume reduction, control of frequently occurring events that form channels, and bed and bank stabilization.

Improving Infiltration & Vegetation in Post-Cons

This webinar will highlight treatment technologies that can be implemented in the construction industry to manage turbidity from dewatering operations. Dewatering methods are briefly introduced; however, the course focuses on best available technologies to treat and polish pumped effluent. Participants will be exposed to a decision matrix that assists in identifying the appropriate treatment for a site specific operation. Upon selection of the treatment, basic design elements are presented for consideration. The webinar targets a broad based audience who can use the information provided as a foundation to then independently research a specific treatment technology in more detail.

Introduction to Erosion and Sediment Control

This course has been developed to introduce participants to the concepts of Erosion and Sediment Control (ESC). It is intended for contractors, developers, consultants, municipal staff, landowners or anyone looking to gain a general knowledge of erosion and sediment control concepts and best management practices. The course is comprised of eight modules and discusses the potential impacts of construction activities, ESC fundamentals, erosion control practices, sediment control practices, in-water and near water works, pollution prevention, winter preparedness and legislation.

Introduction to Low Impact Development

This course has been developed to introduce participants to the concept of Low Impact Development (LID). It is intended for developers, consultants, municipal staff, landowners or anyone looking to gain a general knowledge of sustainable stormwater planning and practices. The course is comprised of four modules, the first discusses the evolution of stormwater management and the progression to LID. The next module introduces the principles of LID and non-structural site design strategies. Eleven LID practices are examined, providing general descriptions, special considerations and an overview of typical stormwater performance expectations in the third module. The final module explores the financial benefits of LID and introduces useful guides and tools that can be used to determine the costs of an LID project.

Maintenance of Permanent Best Management Practices (BMPs)

As more permanent stormwater best management practices (BMPs) are being installed across the nation, performing ongoing maintenance has been a challenge. Permanent stormwater BMPs are now required in most urban developments across the country and it is crucial that these BMPs be maintained correctly. All permanent stormwater BMPs require regular maintenance to remain operating as designed. Maintenance has been neglected in the past due to a failure to understand who is responsible for maintenance, failure to budget for maintenance, and from a lack of knowledge on appropriate maintenance practices. In this webinar, we teach participants to recognize permanent stormwater BMPs in the field, identify maintenance needs and activities, and to perform maintenance correctly. This webinar will provide attendees a broad introduction to the needs and application of permanent stormwater BMP maintenance.

Natural Gas Pipelines

Linear projects, especially natural gas pipelines, present many unique construction and restoration challenges. Additional constraints such as environmental conditions, cultural resources, threatened and endangered species, property owner agreements, right of way access, waterbodies, road crossings and Town/County/State Boundaries further compound the project design, pipeline location and existing resources effected. This workshop presents several examples of linear construction and common problems associated with pipeline construction and restoration. These examples will be followed by creative solutions and out of the box thinking that have yielded successful restoration and compliant results for multiple projects.

Organic, Natural: What's the difference?

There are many terms used to describe the different varieties of erosion control products, like organic, natural, weed free, photodegradable and biodegradable. This presentation will define each of these terms and show you were the products should be used.

Permeable Pavement Design and Construction

Stormwater drainage technology has evolved to the point where it is now possible to create permeable pavements that allow stormwater drainage to occur almost immediately. The benefits to permeable pavements include having rainwater drain directly into soil, decreasing urban heating, and reducing overall stormwater runoff. This concept is gaining acceptance through studies conducted in the United States, the United Kingdom, and Australia. This webinar focuses on what constitutes permeable pavement, design tools and methodologies in designing permeable pavement, the structural and hydrological capacities, and design traffic characterization.

Polymers for Construction Site Erosion and Sediment Control

This course has been developed to familiarize participants with the concepts of polymers and how they can be used for Erosion and Sediment Control (ESC) on construction sites. The course is intended for developers, consultants, municipalities, landowners or anyone looking to learn about polymers and apply them for ESC. This course consists of six modules that discuss the basic concepts of polymers, soil stabilization with anionic polyacrylamide (PAM), PAM based stormwater clarification applications, additional PAM enhanced sediment controls, PAM assisted pond dredging, and anionic PAM application guidance for urban construction.
