Transactions in GIS, Volume 30, Issue 1, February 2026.ABSTRACT Climate change is intensifying the frequency and impact of extreme weather events, particularly in vulnerable Mediterranean environments. This study investigates relative morphometric changes within a gully system in the Guadalmedina River basin (Málaga, southern Spain) triggered by the 2024 DANA (Depresión Aislada en Niveles Altos), a high ...

A procedure for delineating a search region in the UAV-based SAR activities
Geomatics, Natural Hazards & Risk, 2017 We propose a simple geometrical approach for delineating a region above which an Unmanned Aerial Vehicle (UAV) should fly to support the Search and Rescue (SAR) activities.

Earth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.This study combines GPR, 2D ERT and UAV‐derived terrain models to characterize sediment variability in a colluvial‐alluvial plain. GPR identified sandy lenses and clay‐rich layers, while ERT revealed deeper conductive and resistive zones, including a gneissic basement.

Earth Surface Processes and Landforms, Volume 50, Issue 13, October 2025.This study examines large wood (LW) recruitment in the Tegnas Torrent (Italy) after the Vaia Storm. It quantifies floodplain‐recruited LW and analyses reach‐scale correlations with sediment balance and connectivity. Results revealed that wider lateral erosion does not always lead to higher recruitment, as riparian forest characteristics play a key role.

The stratigraphic biography of an archaeological site. Timing depositional events
Archaeometry, Volume 67, Issue S1, Page 49-73, June 2025.Abstract The stratigraphic sequence of an archaeological site constitutes its biography, which details what was deposited, when it was deposited, and how the deposition occurred. However, many current methods of recording archaeological stratigraphy do not allow for a full reconstruction of a site's biography.

STUDY OF THE LANDFORMS OF THE IBICUÍ RIVER BASIN WITH USE OF TOPOGRAPHIC POSITION INDEX
Revista Brasileira de Geomorfologia, 2018 The Topographic Position Index (TPI) is an algorithm which calculates the difference of the elevation between a central pixel ( and the mean of the elevation of its surroundings () surroundings defined by of a radius determined by the user. The study was
