Engineers at the ERDC Coastal and Hydraulics Laboratory (CHL) have developed the Coastal Lidar and Radar Imaging System (CLARIS) to quantitatively measure both subaerial topography and shallow-water bathymetry of coastal regions during storms. CLARIS is a fully mobile mapping system that is designed to operate during storms, collecting topography data of the beach from a terrestrial laser scanner as well as bathymetry and wave data in the surf-zone from radar-derived wave celerity measurements.
