Using sediment dredged from the Atlantic Intracoastal Waterway (AICWW), the project seeks to elevate the marsh platform, countering rapid transitions from vegetated marsh to mudflat.<\/p>\n\n\n\n<p>Adding to this effort, the Engineer Research and Development Center\u2019s Coastal and Hydraulics Laboratory (ERDC-CHL), in collaboration with the University of Washington&#8217;s NSF Natural Hazards Engineering Research Infrastructure (NHERI) Reconnaissance Experimental Facility (RAPID), conducted lidar and multispectral surveys of the nourished areas. Uncrewed aerial systems (UASs) played a pivotal role in capturing high-resolution data from the site, a task otherwise challenging due to limited access during and immediately after material placement.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/ewn.erdc.dren.mil\/wp-content\/uploads\/2024\/12\/FreeflyAlta-X_setup-and-takeoff.jpg\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"421\" src=\"https:\/\/ewn.erdc.dren.mil\/wp-content\/uploads\/2024\/12\/FreeflyAlta-X_setup-and-takeoff-1024x421.jpg\" alt=\"\" class=\"wp-image-20770\" srcset=\"https:\/\/ewn.erdc.dren.mil\/wp-content\/uploads\/2024\/12\/FreeflyAlta-X_setup-and-takeoff-1024x421.jpg 1024w, https:\/\/ewn.erdc.dren.mil\/wp-content\/uploads\/2024\/12\/FreeflyAlta-X_setup-and-takeoff-300x123.jpg 300w, https:\/\/ewn.erdc.dren.mil\/wp-content\/uploads\/2024\/12\/FreeflyAlta-X_setup-and-takeoff-768x316.jpg 768w, https:\/\/ewn.erdc.dren.mil\/wp-content\/uploads\/2024\/12\/FreeflyAlta-X_setup-and-takeoff.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">(Left) Initial set up and (Right) take-off of the Freefly Alta-X outfitted with the Phoenix Lidar Systems MiniRanger.
