TL;DR: Wang et al. as mentioned in this paper integrated the analytical hierarchy process (AHP) with the normalized frequency ratio (NFR) for landslide susceptibility analyses, which can better address issues of the randomness and fuzziness.

TL;DR: In this article, a set of 25 earthquake-induced landslide-events are selected and categorized based on the similarity between causal factors to determine the most relevant training set to make a prediction for a given landslide-event.

TL;DR: In this paper, the authors present changes in retrogressive thaw slump in the Beiluhe Region based on interpretation of satellite imagery, showing that the number of thaw slumps has increased by 253% and the total affected area increased by 617%.

TL;DR: In this paper, the authors focus on rock glaciers as a paraglacial mountain landscape element and consider the relationships between rock glaciers and glacial, periglacial, and paragglacial processes, and show that even within a single region, rock glaciers may have varied origins and thus likely ages and different climatic and environmental controls.

TL;DR: A systematic review of 25 recent studies professing to explain reach-scale channel responses to cumulative impacts of human activities and natural forcing over the recent past (ca. 1880-2005) reveals some consistencies in spatio-temporal response across various catchment sizes (median 3000 km2) in mostly industrialized nations as discussed by the authors.

TL;DR: In this article, the authors compared three remote sensing (RS) approaches: one based on echo sounding (active RS) and two on photogrammetry (passive RS): bathymetric Structure from Motion (SfM) and optical modelling.

TL;DR: In this article, a new method based on GeoDetector and a spatial logistic regression (SLR) model is proposed to select condition factors based on the spatial distribution of landslides.

TL;DR: In this article, the authors used remote sensing and geographic information system tools and techniques, aerial photographs, and satellite imagery have been used to determine epochal channel erosion, accretion, and unchanged locations along Tana River, Kenya's longest river.

TL;DR: In this article, the neighborhood rough set theory is used to identify the triggering factors responsible for landslide deformation, and the most important triggering factors vary between different sites, data types and the time interval used to define them.

TL;DR: In this paper, the outcomes of GNSS, satellite InSAR, and GBInSAR campaigns performed at the Bosmatto landslide (Northwestern Alps, Italy) are presented.

TL;DR: In this article, an extensive bibliographic review and meta-analysis was carried out to explore the main effects of land abandonment of Mediterranean agricultural terraces on local hydrological and geomorphological processes.

TL;DR: In this article, the authors examined a section of a beach-dune system in NW Ireland using Structure from Motion (SfM) and Terrestrial Laser Scanning (TLS) plus baseline dGPS data points.

TL;DR: In this paper, the authors used a wide grain size distribution with unconsolidated dam material to estimate the outflow hydrograph and the resulting inundation of a landslide dam that is breached due to overtopping failure.

TL;DR: In this paper, the flow dynamics within and immediately above an artificial plastic vegetation canopy are measured in the field and wind tunnel, and the results indicate that flow deceleration and drag increases within the canopy as plant density increases.

TL;DR: In this paper, a critical review of landslide classification systems was conducted to identify their limitations, as well as their relevant criteria for classifying loess-slope failures, which is critical for creating a realistic and comprehensive classification system for slope failures.

TL;DR: In this article, the authors investigated the performances of seven public freely-accessed digital elevation models (DEMs) over the HMA region by referring to high-accuracy elevation data from ICESat altimetry.

TL;DR: Variable-importance analyses using information-gain ratio indicate that out of 22 GH-influential factors, land use, slope degree, and slope-length are of more importance in developing of GH occurrence.

TL;DR: In this paper, the authors used river profiles, knickpoint distribution and Chi-map calculation to understand the different degree of erosion of the Duero and Ebro catchments and the dynamics of their drainage network.

TL;DR: In this paper, an integrated study from the NW Mediterranean Sea that couples results of the MARS3D hydrodynamic model with high-resolution sedimentological and geophysical data (piston cores, multibeam bathymetry and high resolution seismic data) is presented.

TL;DR: Li et al. as discussed by the authors investigated the land subsidence in the Beijing Plain over the period of 2003-2015 using ENVISAT ASAR and RADARSAT-2 interferometric datasets and the small baseline subset interferometric synthetic aperture radar (SBAS-InSAR) technique.

TL;DR: In this paper, the morphological change of a semi-sheltered gravel barrier (Start Bay, Devon, UK) is assessed using topo-bathymetric surveys.

TL;DR: In this article, the interactions between flow, vegetation, and sediment documented in inland and tidal marshes, chalk and Coastal Plain streams, large river floodplains, and deltas are reviewed and classified into feedback processes occurring over a range of five spatiotemporal scales.

TL;DR: In this article, a nested numerical approach is proposed to investigate the processes controlling the post-seismic sediment evacuation at the mountain range scale, informed by results from a reach scale model.

TL;DR: In this paper, the authors investigated the morphological characteristics of gullies, the topographic thresholds of gully formation, and estimated headcut retreat rates in three agro-ecologies of the Upper Blue Nile basin, Ethiopia: highland (Guder), midland (Aba Gerima), and lowland (Dibatie).

TL;DR: In this paper, a relationship was found between morphologic characteristics and dune volume changes during storm events producing high water levels, and the model simulations indicated that wave-driven dune growth may occur on low sloping beaches in cases where the dynamic still water level (still water level plus wave setup) is lower than the dune toe.

TL;DR: In this article, a debris flow occurred in the foreland of Gangotri Glacier by its former tributary, Meru (Bamak) Glacier between 16 and 19 July 2017.

TL;DR: In this article, multi-temporal LiDAR-derived DTMs were used to derive DoDs and to perform a multispectral analysis of an index of sediment connectivity in three reaches of a debris-flow channel (Moscardo torrent, eastern Italian Alps) where several check dams have been built over time.

TL;DR: In this paper, the authors analyzed the soil response to exceptional storm events, using 161 source samples collected in a 23 km2 catchment that was mostly cultivated at the beginning of the last century, and calculated the FingerPro unmixing model in the pre-event, regular events and post-event scenarios.

TL;DR: In this article, a sedimentological investigation of a landslide-dammed lake in the upper reach of Lulang River on the eastern Himalayan syntaxis is presented, which shows that the lake formed before 24.2 ka cal. BP and persisted for at least 8.8 ka.
