Description :
Terrestrial Laser Scanning (TLS) is a laser ranging technique, applying the same principles as airborne Lidar. It offers a new methodology for the rapid acquisition of high-resolution and high-precision surface elevation data from in situ sediments. This paper presents the use of TLS as an alternative method for collecting high-resolution 3D data from fluvial gravel surfaces, enabling the development of grain-scale Digital Terrain Models (DTMs). Application to a coarse grained gravel system, the River Feshie, in Scotland, and a second river, Bury Green Brook, dominated by finer gravel, in Hertfordshire (England). Results and discussion.
