LiDAR-derived Digital Elevation Models (DEMs) and Geographic Information Systems (GIS) were employed to identify, characterize, and map fluvial features, leading to the delineation of Potential Terrace Areas (PTAs). Complementary, a geochronological framework was established through Optically Stimulated Luminescence (OSL) and Electron Spin Resonance (ESR) dating of fluvial terrace sequences. Despite recurring challenges, including poor terrace preservation due to slope processes, vegetation, and urbanization, as well as problematic luminescence and ESR signal properties¿the study defines a consistent stratigraphic architecture across the region. Nine recurrent terrace levels (T1¿T9, from +120 m to +5 m) were recognized, with preliminary ages indicating that the lower terraces (+10 m to +25 m) formed during the Middle Pleistocene (~140¿400 ka). These findings demonstrate a coherent regional pattern of fluvial development, highlighting the role of climate fluctuations and tectonic activity in shaping the Quaternary landscape of the eastern Cantabrian valleysIriarte Avilés, EnekoAranburu Artano, Arantza2026202620252025info:eu-repo/semantics/doctoralThesisapplication/pdfhttp://hdl.handle.net/10810/77638reponame:Addi.
