The scale levels identification for the plowland topography organization

Бюллетень Почвенного института им. В.В. Докучаева, 2019
The identification of factor and indicational features, which are characterized by the high informativity and field of view in relation to the soil cover organization, plays a very important role in the soil mapping.

Detailed hydrogeomorphic analysis in the Gerecse Mountains, Hungary

Acta Universitatis Sapientiae: Agriculture and Environment, 2016
The northern foreland of the Central Gerecse Mountains is a complex landscape with a moderate relief and the presence of terrace remnants. To explore the hydrogeomorphic settings, the characteristics of the drainage network, several basin metrics, and ...

Complementary geophysical, geomorphometric and pedological approaches for characterizing shallow and deep subsurface materials in a colluvial‐alluvial plain in Atlantic rainforest

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.

Large wood recruitment in the Tegnas torrent (Italy): The impact of the Vaia storm and the role of the riparian forest structure

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.

Lineament depth deduction using geomorphometry and 3D Euler solution

Acta Geophysica
In this paper, we present a novel method for determining the depth of lineaments using satellite gravity data, which we test in the Sahel of Sfax area (eastern Tunisia). This region has a relatively flat topography with few significant discontinuities at

Ranking of 10 Global One-Arc-Second DEMs Reveals Limitations in Terrain Morphology Representation

Remote Sensing
At least 10 global digital elevation models (DEMs) at one-arc-second resolution now cover Earth. Comparing derived grids, like slope or curvature, preserves surface spatial relationships, and can be more important than just elevation values.

Quantifying streambank erosion: A comparison of physical surveys, aerial imagery and UAS LiDAR surveys

Earth Surface Processes and Landforms, Volume 50, Issue 6, May 2025.
Four methods were used to quantify short‐term (1–2 years) reach‐wide streambank erosion rates along three low‐order streams in western Virginia: (1) bank height and cross‐section (XS) surveys, (2) bank height and top of bank (TOB) surveys, (3) bank height survey and aerial imagery analysis and (4) DEM of Difference (DoD) using UAS LiDAR with channel ...

Geomorphometry and Statistical Analyses of Landslides Triggered by the 2015 M w 7.8 Gorkha Earthquake and the M w 7.3 Aftershock, Nepal

Frontiers in Earth Science, 2020
The 2015 M w 7.8 Gorkha earthquake in Nepal and the M w 7.3 aftershock triggered at least 22,914 landslides that each had areas ≥500 m2 and lengths and widths ≥20 m. Amongst these landslides, 2,059 had areas >10,000 m2. Analyses of the landslide geometry,
