Understanding of breaking and broken waves is key for the prediction nearshore sediment transport coastal hazards, however difficulty obtaining measurements highly unsteady has limited availability field data. This paper reports on a novel experiment designed to capture time-varying free-surface throughout surf swash zones was conducted dissipative sandy beach using an array 2D LiDAR scanners. Three scanners were deployed from pier at Saltburn-by-the-Sea, UK 6 day period monitor surface...
A low-cost multicamera Unmanned Aircraft System (UAS) is used to simultaneously estimate open-coast topography and bathymetry from a single longitudinal coastal flight. The UAS combines nadir oblique imagery create wide field of view (FOV), which enables collection mobile, long dwell timeseries the littoral zone suitable for structure-from-motion (SfM), wave speed inversion algorithms. Resultant digital surface models (DSMs) compare well with terrestrial topographic lidar bathymetric survey...
The Coastal Imaging Research Network (CIRN)'s Quantitative Toolbox is a collection of MATLAB scripts to produce georectified images specifically tailored for quantitative analysis coastal environments. repository contains that perform end-to-end georectification oblique imagery from land-based multi/single-camera stations or stationary Unmanned Aircraft Systems (UAS). toolbox produces frames, ensemble statistical products, and subsampled pixel collections optical wave, current bathymetric...
Estimation of nearshore bathymetry is important for accurate prediction wave conditions. However, direct data collection expensive and time-consuming while airborne lidar-based survey limited by breaking waves decreased light penetration affected water turbidity. Instead, tower-based platforms or Unmanned Aircraft System (UAS) can provide indirect video-based observations such as time-series (or videos) time-averaged (Timex) variance enhanced (Var) images. The imagery celerity information...
The presented study reports on numerical simulations of flows in tidal channels near Rose Dhu Island, GA, which is used to identify hotspots hydrokinetic energy and assess the stream potential at this site. are complemented with field measurements local current velocities water surface heights, validate simulations. Both velocity distributions heights as predicted by model good agreement observed data. reveal a asymmetry encompassing Ogeechee estuary ebb tide currents dominating over flood...
The use of small unmanned aircraft systems to collect 3-D topographic data for a variety geophysical applications has exploded in the last decade. These are often produced from imagery using structure-from-motion (SfM) algorithms with or without ground control. While accuracy these products been assessed number efforts, comparatively little focus placed on estimating spatially varying ground-space uncertainties final rigorous error propagation methodology and uncertainty estimation....
The capability of a commercial off-the-shelf amphibious bottom crawling robot is explored for surveying seamless topography and bathymetry across the beachface, surfzone, very nearshore. A real-time-kinematic (RTK) antenna on mast was added to robotic platform, Bayonet-350 (previously C2i SeaOx). Data collected from were compared with those by Coastal Research Amphibious Buggy (CRAB) Lighter Resupply Cargo (LARC), unique vessels capable collecting in use decades at US Army Engineer...
Unexploded ordnance (UXO, also referred to as munitions) are located in nearshore and other underwater environments a result of military activities. UXO have been found the surf zone on populated beaches. This paper describes development evaluation instrumented surrogates for observing munitions migration burial. Surrogates were designed fabricated match mass properties variety common (81-mm Mortar, BLU-61 Cluster Bomb, M151-70 Hydra Rocket, M107 155-mm). housed suites self-logging sensors....
