The Natural Infrastructure Opportunities Tool; presented by Dr. Safra Altman (bio PDF), from ERDC Environmental Laboratory. The Natural Infrastructure Opportunities Tool (NIOT) is a web viewer designed to help discover natural infrastructure connections and inspire innovative opportunities. The NIOT uses map-based visualizations of environmental, geomorphic and sediment conditions, as well as upcoming USACE projects, and also serves as an interface for users to add their resource needs and resource availability.

Leveraging Technology to Prevent Looting and Destruction of Archaeological Sites: Real-Time Effects Cultural Evaluation Networking Tracking, Planning, and Sensitivity Tool (RECENTPAST); presented by Michael Fedoroff (bio PDF), from USACE-TNTCX and Brian Zettle (bio PDF), from USACE-SAM.
Increased demand for illegally obtained artifacts results in widespread destruction and looting of archaeological sites on Federal property. New and innovative approaches must be taken to combat such activities. The RECENTPAST Geographic Information Systems (GIS) tool was developed by United States Army Corps of Engineers (USACE) Tribal Nations Technical Center and Mobile District to manage cultural resources with the best technology available. This technological strategy has aided in the conviction of several looting cases within the District and transformed a reactive management strategy into a proactive strategy of stewardship. Additionally, it has been implemented in offshore dredging applications aiding in cultural resource protection offshore.

Bioaccumulation Control at Open Water Placement Sites by Dredged Material Amendment with Activated Carbon; presented by Dr. Paul Schroeder (bio PDF), from the Environmental Laboratory. Sediments in urban harbors often cause elevated poly-chlorinated biphenyls (PCBs) bioaccumulation, limiting their suitability for beneficial use or placement in aquatic sites. This presentation examines:
- Activated carbon dosage requirements for bioaccumulation control
- The efficacy of mixing activated carbon within a barge using conventional dredging equipment
- The spreading and losses of activated carbon during conventional placement of amended dredged material through 15 meters (50 feet) of water (demo at Ashtabula Open Water Placement Site)
- Effectiveness of field application
- Impacts on benthic organisms

Impacts of Mud Aggregate Processes on Sediment Transport in Dredging Projects; presented by Dr. Jarrell Smith and Mr. David Perkey from the Coastal Hydraulics Laboratory. Learn how mud aggregates impact sediment transport processes and why it matters to dredging projects. Get a glimpse of data from ongoing research then a sneak peak at future guidance to include aggregate processes in modeling and project designs.

Addressing Potential Dredging Operation Impacts on the Federally Endangered Atlantic Sturgeon; presented by Dr. Matthew Balazik (bio PDF) and Mr. Justin Wilkens (bio PDF), from the ERDC Environmental Laboratory. Mr. Wilkens began the webinar with a presentation about the results from a laboratory test performed at the ERDC, Vicksburg, MS, USA, investigating the effects of suspended sediment on short-term survival and swimming performance of juvenile Atlantic sturgeon. Following this presentation, Dr. Balazik presented findings from field work investigating Atlantic sturgeon movements in relation to an active dredge in the James River, VA, USA. The goal of this research was to generate data through laboratory and field studies to help evaluate the effectiveness of environmental windows intended to protect the Atlantic sturgeon.

Dredging Data Extracts: A Century of USACE Dredging Activities; presented by Dr. Brandan Scully (bio PDF), from the ERDC Coastal & Hydraulics Laboratory. The Dredging Innovations Group extracted useful dredging data in a compact form from over 100 years of Annual Reports on Civil Works. The extracted data has a variety of uses within the USACE navigation, flood risk management, and environmental business lines, and is available here.

Biological Effects of Dredging-Induced Underwater Sounds; presented by Dr. Andrew McQueen (bio PDF), from the ERDC Environmental Laboratory. There is increasing concern related to adverse biological effects associated with anthropogenic input of sounds to the underwater soundscape. The goal of this research was to document adverse biological effects of underwater sound from dredging activities to discern potential ecological risks.
