    Evaluation of Unmanned Aircraft System Coastal Data Collection and Horizontal Accuracy: A Case Study at Garden City Beach, South Carolina

    Abstract: The US Army Corps of Engineers (USACE) aims to evaluate unmanned aircraft system (UAS) technology to support flood risk management applications, examining data collection and processing methods and exploring potential for coastal capabilities. Foundational evaluation of the technology is critical for understanding data application and determining best practices for data collection and processing. This study demonstrated UAS Multispectral (MS) and Red Green Blue (RGB) image efficacy for coastal monitoring using Garden City Beach, South Carolina, as a case study. Relative impacts to horizontal accuracy were evaluated under varying field scenarios (flying altitude, viewing angle, and use of onboard Real-Time Kinematic–Global Positioning System), level of commercial off-the-shelf software processing precision (default optimal versus high or low levels) and processing time, and number of ground control points applied during postprocessing (default number versus additional points). Many data sets met the minimum horizontal accuracy requirements designated by USACE Engineering Manual 2015. Data collection and processing methods highlight procedures resulting in high resolution UAS MS and RGB imagery that meets a variety of USACE project monitoring needs for site plans, beach renourishment and hurricane protection projects, project conditions, planning and feasibility studies, floodplain mapping, water quality analysis, flood control studies, emergency management, and ecosystem restoration.

  • Green Peter Dam less risky after extensive studies, rehab and assessment

    After years of extensive studies, a risk assessment and recent rehabilitation of spillway gates, officials re-classify Green Peter Dam, near Sweet Home, Ore., as a Low Risk dam. Recent rehabilitation of the spillway tainter gates for trunnion friction and overall reliability have improved the risk characterization. These efforts along with a detailed review of the dam’s hazards, performance and consequences, helped decrease risks from the last assessment, which rated Green Peter as a High Risk dam.
  • Northwest Tennessee Regional Port Authority and Corps to sign new Project Cooperation Agreement

    WHAT: The Northwest Tennessee Regional Port Authority and the U.S. Army Corps of Engineers Memphis District will hold a Project Cooperation Agreement (PCA) Signing Ceremony.
