Vegetation characteristics providing spatial heterogeneity at the channelreach scale can produce complex flow patterns and the relationship betweenplant patterns morphology and flow resistance is still an open question (Nepf2012). Unlike experiments in laboratory, measuring the vegetationcharacteristics related to flow resistance on open channel in situ isdifficult. Thanks to its high resolution and light weight, scanner lasers allownow to collect in situ 3D vegetation characteristics. In this study we used a1064 nm usual Terrestrial Laser Scanner (TLS) located 5 meters at nadir above a8 meters long equipped channel in order to both i) characterize the vegetationstructure heterogeneity within the channel form a single scan (blockage factor,canopy height) and ii) to measure the 2D water level all over the channelduring steady flow within a few seconds scan. This latter measuring system waspossible thanks to an additive dispersive product sprinkled at the watersurface. Vegetation characteristics and water surfaces during steady flows from6 different plant spatial design on channel bottom for 4 plant species werethus measured. Vegetation blockage factors at channel scale were estimated fromTLS points clouds and analyzed.
