Summary: This study evaluates the viability of using soil NIR spectroscopy as a rapid and cost-effective way to differentiate between various fluvial terrace levels. By analyzing the correlation between soil NIR spectra and the height above river channel (HARC) of different terrace levels, as well as using machine learning algorithms for classification, the study demonstrates the clear potential of NIR spectroscopy as an alternative to traditional field interpretations for fluvial terrace differentiation.

Summary: Plate convergence rates strongly influence seismicity and mountain building inboard of convergent margins, but the distribution and kinematics of structures accommodating far-field convergence can be elusive. In interior Alaska, Yakutat microplate convergence drives late Pleistocene-recent right slip on the Denali fault, but westward-decreasing slip rates leave substantial residual Yakutat motion unaccounted for. Our study reveals that Northern Foothills thrust slip beneath the northern Alaska Range absorbs a significant portion of the residual Yakutat convergence, and rapid slip at a steep thrust ramp beneath the range front accommodates the geodetic gradient and drives rock uplift at rates matching measured incision rates.

Summary: This study compares two GIS-based bivariate statistical methods for landslide susceptibility analysis at the catchment scale, introducing a new method for delineating slope units and testing the morphometric slope index as a predisposing factor for landslides, resulting in susceptibility maps with strong geomorphological significance. The efficiency of slope unit segmentation and the potential of the statistical methods proposed for landslide susceptibility mapping are demonstrated in this research.

Summary: This paper assesses the long-term downcutting pattern and driving mechanisms of the Upper Ebro River, and reconstructs the valley incision process using river terraces. The study reveals a long-term deceleration in incision rates and suggests that climate change alone cannot explain the observed pattern. Instead, the decrease in incision rates is attributed to base level lowering effects caused by the opening of the Ebro Cenozoic Basin.

Summary: The study reveals that geomorphological processes have a significant impact on the functional traits of Arctic plant communities, with cryoturbation being the most influential factor on structural and leaf economic traits. The results show consistency across different regions, indicating a coherent biome-level trait response to geomorphological processes.

Summary: Fine-resolution LiDAR DEMs can accurately represent surface features such as road and railway embankments. A novel algorithm was proposed to identify embankments in LiDAR DEMs, achieving moderate to high accuracy. The technique showed good performance on test DEMs from southwest Ontario, Canada, with acceptable processing times for practical applications.

Summary: This study analysed five commonly used DEMs to assess their suitability for calculating tectonogeomorphic indices. The results showed that Copernicus and TanDEM-X performed the best, followed closely by AW3D30, while ASTER GDEM3 performed the worst. The study provides a clear guideline for the scientific community on which DEMs to choose for calculating various tectonogeomorphic indices.

Summary: The current landforms in the Bakircay and Madra River catchments near ancient Pergamon show a horst-and-graben structure shaped by tectonic activities. The asymmetry in relief between the north and south characterize the Pergamon Micro-Region, which, coupled with its agricultural suitability and natural resources, led to human settlement and landscape engineering measures being implemented.

Summary: This study presents a high resolution paleo-coastline model for the isolated limestone massif of Trảng An, Ninh Bình province, Vietnam. The archaeological and paleoecological records within this area provide valuable insights into human activities and landscape transformations under past sea level changes. The well-preserved notches along the vertical limestone cliffs reveal stable sea level phases during the Mid-Holocene marine transgression and allow for detailed coastline reconstructions. This data improves understanding of past human adaptations to climate change-induced sea level rise and informs current coastal vulnerability assessments and climate change response models.

Summary: This paper discusses the potential response of fluvial processes and landforms to the projected permafrost degradation and related hydrological change. The paper outlines the structure of fluvial systems and their dependence on permafrost, distinguishing between landforms that will adjust to future hydrology and those influenced by permafrost disturbances. The paper highlights the varying impacts of permafrost on fluvial action in different compartments and discusses the expected changes in each compartment based on projected permafrost and hydrological changes. The paper also emphasizes the collateral effects of fluvial change and the need to consider them in climate change adaptation and mitigation strategies.

Summary: This study focuses on Deep-Seated Gravitational Slope Deformations (DSGSDs) in the Molise region of Italy. A combination of aerial-photo interpretation, morphological analyses, field surveys, and satellite SAR interferometry was used to detect and map these phenomena. The resulting map includes an inventory of DSGSDs, geological and orographic features, a geostructural scheme, cross sections, and geomorphometric and landslides maps. This research provides a comprehensive inventory and understanding of DSGSDs in the Molise region, and establishes a correlation between the deformations and the region's geological and geomorphological setting.

Summary: The full description of the rock mass behaviour in slope deformation and failure is still challenging in numerical simulations. This study focuses on the multistage creep evolution and progressive failure of jointed rock mass in the Mt. Conero coastal sector. By using the finite difference method, a numerical backanalysis was conducted to simulate the creep process, progressive failure, and damage accumulation. The modelling results suggest that the landslide event consisted of two distinct episodes at approximately 56 ka and 16 ka, consistent with relative dating constraints. The study also highlights the importance of the creep process in controlling slope evolution and the reliability of the analytical approach for analyzing progressive brittle rock failure.

Summary: Rapid slope instabilities in mountainous areas pose a threat to facilities and life. This study used satellite and UAS-based products, along with PS-InSAR analysis, to identify different degradation processes leading to rock mass destabilization. The combination of object-based multispectral classification and change detection analysis highlighted areas susceptible to deterioration, while PS-InSAR analysis provided multi-temporal information at the catchment scale. This approach offered a multiscale perspective of denudation and mass-wasting processes, detecting evidence and/or early precursors of rock collapses and supporting asset management practices.
