Wade Burcham, Robert Dunn, and Alessandra Braswell to Present at the American Ecological Engineering Society 2019 Annual Meeting in Asheville, North Carolina

Wade Burcham, P.E., LEED AP (Alabama), Robert Dunn (Georgia), and Alessandra Braswell, Ph.D., P.E. (North Carolina) will lead sessions at the American Ecological Engineering Society (AEES) 2019 Annual Meeting in Asheville, North Carolina on June 3-6, 2019.

Meet with Wade, Robert, and Alessandra at the Geosyntec Booth.

Wade is a Principal Water Resources Engineer based in Alabama with more than 21 years of professional experience focused on natural stream stabilization, water resources engineering, stormwater management, municipal engineering, and contract administration.

Robert is a Water Resource Scientist and Aquatic Ecologist based in Georgia, focused on natural resource and ecological consulting for streams, rivers, lakes, and coastal ecosystems.

Alessandra is a Water Resources Engineer based in North Carolina, focused on urban stormwater management, stormwater control measure (SCM) selection and design, and stormwater master planning.

This year’s meeting, themed "Enabling Future Generations to Solve Our Planet’s Grand Challenges," allows science and engineering students to showcase their work in the field and bring them together with industry professionals who can provide guidance and insights to entering the industry.

The AEES promotes the development of sustainable ecosystems that integrate human society with its natural environment for the benefit of both by fostering education and outreach, extending professional development and associations, raising public awareness, and encouraging original research.

Title: Stabilization Alternatives – Living Walls – Another Choice to Consider
Presenter: Wade Burcham
Abstract: Often there are better design options to protect stream banks and shorelines than traditional hard measures. Ideally, we want to use Mother Nature as a template, and utilize design concepts that incorporate only natural materials. However, projects occasionally present with situations such as schedule limitations (e.g. emergency repairs) or physical limitations (e.g. lack of space) that require the consideration of traditional measures. Designers must be able to rapidly sift through their toolbox of ideas to quickly determine the best solution. This presentation seeks to provide designers and planners with another tool to place in their toolbox; a tool that can meet many project limitations and is regenerative. It can be used to retrofit and enhance traditional designs and methods. This design tool is living walls. Living walls such as Filtrexx’s GreenLoxx® products, applications, and resources will be presented, along with case studies that describe considerations for product selection, design, construction, and lessons learned. Examples of both Non-MSE and MSE living walls will be presented, as well as a summary of some quantitative environmental impacts.

Title: Lidar and Geomorphic Change Detection: Useful Tools for River Ecosystem Assessment and Restoration Monitoring
Presenter: Robert Dunn
Co-Author: David Vance, Geosyntec
Abstract: Traditional stream survey methods have long been the preferred method for river ecosystem assessment and monitoring, however, topographic surveys, utilizing newer methods (UAVs, ground-based Lidar, survey-grade RTK GPS, etc.) are increasingly becoming more common in river ecosystem assessment and restoration monitoring. UAVs equipped with high-resolution Lidar scanners offer a suite of benefits for river restoration practitioners, including increased spatial coverage and data density, allowing practitioners to repeatedly collect topographic and geomorphic data beyond the traditional reach-scale, with less time than traditional methods. Further, the repeated acquisition of high-resolution topographic surveys over a river ecosystem allows assessment and/or monitoring of geomorphic change to be expanded spatially beyond reach-scale cross-sections and longitudinal profiles.

Employment of Geomorphic Change Detection (GCD) methods to repeat high-resolution topographic surveys of a river system allow practitioners to better understand the geomorphic rate and magnitude of change and how this relates to stream-system processes influencing form and function of a river system, especially in post-restoration scenarios. This presentation will highlight the use of UAV based Lidar in river assessment and monitoring. Additionally, the use of GCD software to generate spatially distributed maps of elevation, volume, and areal change will be presented, which portray a detailed depiction of the magnitude and extents of change at the reach and larger spatial scales.

Title: Stormwater Management for Coastal Communities
Presenter: Alessandra Braswell
Abstract: Designing stormwater management systems for coastal communities can be challenging due to many environmental factors. High groundwater, tidal effects, and flat topography present a reduced opportunity for gravity-driven systems; conventional "pipe and pond" methods are thus often not applicable. Additionally, sea level rise and a changing climate add an inherent level of complexity in designing drainage and stormwater management solutions for coastal communities compared to other regions. This presentation will cover a selection of stormwater management projects implemented in coastal communities. These case studies showcase some of the basic stormwater design principles for coastal communities, including methods like infiltration at the source, groundwater lowering, and retrofit improvements that consider tidal influences. Lessons learned and opportunities for improvement will be highlighted.
