Characterization of riparian zones in wallonia (belgium) from local to regional scale using aerial lidar data and photogrammetric DSM ; Utilisation de données LiDAR et de MNS photogrammétrique pour la caractérisation des bandes riveraines en Wallonie (Belgique) de l'échelle locale à l'échelle régionale

peer reviewed ; The present study proposes an innovative approach to automatically extract riparian zone characteristics in order to assess its quality, from pre-determined river management reaches (1-3 km long) to regional scale (ca. 13000 km for 1000 management sectors). The aim of this remotely sensed monitoring is to improve the river and riparian zone management and planning by providing some key information for river managers. The methodology was developed based on two watersheds covering approximately 500 km of river network (ca. 200 management sectors). The riparian zone quality is eva... Mehr ...
