Abstract
In this work we propose a methodology for detection of fluvial terraces based on Digital Elevation Models and LiDAR data. The process consists of a treatment of LiDAR data with Geographic Information Systems, later combined with digital stereoscopic photointerpretation and fieldwork. The work has been carried out in the Oiartzun river valley, in which eleven potential terrace levels have been detected: T2, T5, T7, T10, T17, T25, T30-35, T50-60, T75-80, T100 and T120-130. It has been possible to verify both the effectiveness of the GIS method and the validity of the LiDAR data for the detection of fluvial terraces, as well as checking up on its purpose for limiting potential study areas quickly and accurately. Afterwards, a more extensive characterization of the fluvial deposits, sedimentological and chronostratigraphic studies should be done for the study of the Quaternary evolution of the Oiartzun Valley.
