Abstract

The potential for geomorphological mapping and quantitative calculations of light detection and ranging (LiDAR) data within fluvial geomorphology was studied for 2 river catchments within Belgium (Dijle and Amblève), which differ in physical settings and floodplain morphology. Qualitative analysis of LiDAR data allowed the identification of former channel patterns, levees, colluvial hillslope and fan deposits. These results were confirmed by field data, topographic surveys and historical maps. The main aim of this study is to critically compare and evaluate information derived from regional LiDAR imagery and ground truth data in order to assess their suitability for geomorphological mapping in these environments. Furthermore, the AA. investigated whether a comparison of recent LiDAR data with historical information could be used to derive quantitative information on river and floodplain morphological changes
